About OEL 5.4 kernel
Hi,
I have tried with OEL5.4.It has 2.6.18 kernel.But higher version 2.6.32 is also available.Is there any specific reason to inlcude lower version?
Frits is correct, but let me elaborate.
Also, Oracle Enterprise Linux is a freely-available version of its Red Hat counterpart. A distribution release is a snapshot in time, and enterprise-level customers prize stability. As a wise man once told me: "Newness is not a virtue." He was right.
The key point here is software configuration control.
So, a distribution release point comes when a group of packages is considered to work well together. Bingo, burn a DVD. Lock down the package versions. On to the next release...
Bugs crop up, and are fixed. These are the errata updates, and you need an Unbreakable Linux Network license to get them. But the distribution release versions are not altered: a 1.0 distribution release remains a 1.0 distribution release forever. If you hit the bug and need the update, then you graft the new package version into your local package inventory, but that does not change the canonical original release.

Question about ASE 15.7 kernel mode – process vs threaded
Hi there,
This question is related to upgrading Sybase ASE Server
from version 15.5 to version 15.7 on Sun Solaris SPARC Operating System
(Solaris 10). For the upgrade, I need to choose between threaded kernel and
process kernel mode.
1> Is the process kernel mode in ASE 15.7 identical to
process kernel in ASE 15.5? Are there any changes to process kernel mode
between version 15.5 and 15.7? With all the other configurations on the Solaris
host being same (Number of CPUs, RAM, Storage, Sybase ASE Configuration
parameter values like total memory, engines), will the performance on ASE 15.7
in process kernel mode be same as on ASE 15.5?
If there are differences in performance, what are they? What should I be monitoring on ASE 15.7 to see
if there is performance issue on the ASE Server?
2> For the threaded kernel mode, are there any performance
overheads like more CPU usage? We are not planning to change the hardware
configuration of the Solaris host during the upgrade. What values should I be monitoring at the OS
level OR Sybase ASE level to make sure that there are no performance issues? Is
there any particular parameter that needs to be monitored closely when we
change to threaded kernel mode?
Are there any Sybase Configuration parameters that I need
to tune for the New threaded kernel mode? If so, do you have any performance
tuning tips (white papers, technical documents) for threaded kernel mode?
3> What is SAP Sybase recommendation on which Kernel mode I
should be using? I researched the SAP Knowledge Base articles for
recommendations on which Kernel mode to use and I could not find a definitive answer.
Thanks,
RajActually with Solaris on SPARC, there is a very key consideration - you should be on ASE 15.7 sp50 or sp100 or higher AND have applied the kernel jumbo patch (Oracle BugID 16054425) from Solaris that fixes the issue in which they prohibited OS threads from issuing KAIO calls. Then in ASE, you need to configure the 'solaris async i/o mode' parameter.
The changes between threaded and process mode kernels should be transparent to your application. Generally speaking, SAP recommends 'threaded' kernel mode - and specifically for SAP applications only certifies 'threaded' kernel mode. For custom applications, you *could* use either - although, depending on how many engines you run and what chipset you are on, you might see better performance with one vs. the other - typically threaded kernel mode is better, although there are exceptions.
Generally, the main difference is that in process kernel mode, each engine did disk and network IO polling. Due to OS security restrictions, this often meant that a engine had to process the disk IO in which it submitted...or for networking, your SPID had to run on your network engine for any network IO. In threaded mode, there is a single parent process with engine tasks (threads) and IO tasks (threads). Consequently, for customers used to running in the 10's of engines, we suggest a starting point of reducing the number of engines by 2 to give the IO tasks CPU time.
One reason why threaded mode is often better is due to OS scheduling. With hardware threaded cores, most OS dispatch schedulers do a better job of spreading the threads across the cores before utilizing the threads when a process is multi-threaded with POSIX threads - then a multi-process/kernel threaded implementation. At one customer, we proved that we consistently got the best performance with threaded kernel and the only way we could match it with process kernel was to use OS cpu affinity to bind the ASE engine processes to individual cores.
However, one consideration is that older SPARC Niagara chips (T1-T4) were notoriously bad at network handling for some reason. As a result, one of the recommendations for ASE on SPARC Niagara chips is to run the same number of network engines as the number of cores ASE is using. One solution to that is in Solaris 11 (I think) where Solaris finally started being able to handle network interrupts better - I also think the T5/T6 are much better chips - but I have no customer experience data to go on there. -
A little question about compiling my own kernel
Hii, How can I know please, wich moudle is loaded in my current kernel and being used?
for example, if I have now the RAID xxxx , and I don't use it, so when compiling my own Kernel, I don't need it.
How can I know wich ones arn't needed?Ok Lsmod I know, is there any thing else?

Question about using uuid in kernel boot argument
Have my root partition on sda3 with uuid-> 81222792-bd9f-47d6-8d28-b4b59d93cbac
Grub is able to boot if I use either:
root=/dev/sda3
or
root=/dev/disk/by-uuid/81222792-bd9f-47d6-8d28-b4b59d93cbac
But not by using:
root=UUID=81222792-bd9f-47d6-8d28-b4b59d93cbac
Do I need to do some steps if I want to use root=UUID=xxx syntax in the root partition of the grub/grub2 bootloader?Found this link on Google http://en.gentoo-wiki.com/wiki/Initramfs. In short it tells that you need some support in the initrd image. Since both kernel26.img and kernel26-fallback.img failed to boot using root=UUID=xxxx syntax, then I guess that support is not included by default on our images.
Since working/hacking the initrd/mkinitcio is atm too much for me to handle, I hope someone with more experience can give me some light in the issue. -
Why is kernel-2.6.9 (OEL-4) faster than kernel-2.6.18 (OEL-5) ?
Hi,
as long as RHEL-5 and then OEL-5 have been released, I have been wondering why my own programs, compiled and run on RHEL-5/OEL-5, are slower than the same programs compiled and run on RHEL-4/OEL-4 on the same machine. This is really barmy since gcc-4.1, shipped with RHEL-5/OEL-5, is very aggressive compiler and produces faster binary code than gcc-3.4.6, shipped with RHEL-4/OEL-4. I verified this hundred times testing both compilers on RHEL-4/OEL-4 and RHEL-5/OEL-5. The 4.1 compiler always produces faster executable on the same OS.
The problem is obviously in kernel-2.6.18. There is something in the kernel (maybe scheduler?) that slows down the execution of programs. But what? I experimented with changing various kernel boot parameters (eg "acpi=off" etc), even tried to recompile the kernel many times with various combinations of config parameters, and nothing helps. Thus, I'm still wondering whether the problem is solvable by disabling one or more config parameters and recompiling the kernel, or is deeply embedded in the main kernel code.
Is there anybody in this forum who experienced the same, say running OEL-4 before migrating to OEL-5?
Here are two examples showing different execution times on OEL-4.5 (kernel-2.6.9-55.0.5.0.1.EL.i686, gcc-3.4.6-8.0.1) and OEL-5 (kernel-2.6.18-8.1.10.0.1.el5, gcc-4.1.1-52.el5.2). The first example is trivial but very sensitive to overal system load and kernel version. The second example is "Sieve of Eratosthenes" - the program for finding prime numbers (CPU bound).
EXAMPLE 1.
/* Simle program for text screen console */
/* very sensitive to overall system load */
/* and kernel version */
#include <stdio.h>
int main(void)
register int i;
for(i = 0; i < 1000000; i++)
printf(" %d ", i);
return 0;
/* end of program */
$ gcc -O2 -o example1 -s example1.c
$ time ./example1The average execution times on OEL-4.5 and OEL-5 are as follow:
Mode OEL-4.5 OEL-5
real 0m3.141s 0m4.931s
user 0m0.394s 0m0.366s
sys 0m2.747s 0m4.563s
----------------------------------As we can see, the program on the same machine, compiled and run on OEL-4.5 (gcc-3.4.6 and kernel-2.6.9) is 57% faster than the same program compiled and run on OEL-5 (gcc-4.1.1 and kernel-2.6.18), although gcc-4.1.1 produces much faster binary code. Since the times the process spent in user mode are almost equal on both OS, the whole difference is due to the time the process spent in kernel mode. Note that kernel mode (sys) is taking 66% more time on OEL-5. It tells me that "something" in the kernel-2.6.18 slows down the execution of the program.
In the second example OEL-4.5 is also faster than OEL-5, but the differences in execution times are not so drastic as in the first example.
EXAMPLE 2.
/* Sieve of Eratosthenes */
#define GNUSOURCE
#include <stdio.h>
#include <stdlib.h>
#define MAX_PRIME_AREA 100000
#define REPEAT_LOOP 10000

exit(EXIT_FAILURE);
for(count = 0; count < REPEAT_LOOP; count++)
for(prime = 0; prime < (MAX_PRIME_AREA + 1); prime++)
*(sieve_array + prime) = (char) '\0';
for(prime = 3; prime < (MAX_PRIME_AREA + 1); prime += 2)
if (! *(sieve_array + prime) )
*(sieve_array + prime) = (char) 'P'; /* offset prime is a prime */
for(composite = (2 * prime); composite < (MAX_PRIME_AREA + 1); composite += prime)
*(sieve_array + composite) = (char) 'X'; /* offset composite is a composite */
/* DO NOT COMPILE FOR TEST !!!
fprintf(stdout, "\n%d\n", 2);
for(prime = 3; prime < (MAX_PRIME_AREA + 1); prime += 2)
if ( *(sieve_array + prime) == 'P' )
fprintf(stdout, "%d\n", prime);
free(sieve_array);
return 0;
/* End of Sieve of Eratosthenes */The average execution times on the same machine on OEL-4.5 and OEL-5 are:

N.J.An hour? Hard to believe or is your hardware that
old?An hour? That's a super good time for 3 kernel
packages (i686, xen and PAE) with all modules, plus 3
kernel-devel packages, plus debuginfo package of
150-580 MB where smart people at Red Hat decided to
put uncompressed vmlinux image which is necessary for
kernel profiling and debugging. Ah, I had a different kernel make process in mind.
Oracle doesn't ship
debuginfo package. Of course, this is when I build a
"complete suite" of kernel rpm packages using
unmodified spec file. And, to be honest, it takes
much more than an hour, maybe even two hours. Another
thing is compiling single i686 kernel without
building a package. But it also takes at least half
an hour. Anyway the time significantly depends on how
many modules are selected to be built in.That what I was looking for.
What's your time to build a single kernel (which
version?) with default set of modules ? On which
hardware ? I've only access to a root server right now, which is
cat /proc/cpuinfo | grep "model name"

About compiling a kernel with ABS
So I was following the guide on the wiki about compiling a new kernel with ABS. I wanted to try and make a kernel that didn't need to use initramfs. I thought I could do it by not enabling the kernel to have the ability to use initramfs, and I think I also added the right modules to be built into it not have them be modules ( any idea if I can make sure I chose the correct drivers). After I was done I needed to install in using pacman -U. It told me it conflicted with kernel26 or something, and it asked if I wanted to replace it. Do I want to replace the current with the new? Or can I have them side by side? I know I can have multiple kernels, so it confused me a little.
Still new with all this, but I'm pretty sure you don't want to replace your current kernel, or you could mess your system up should your newly compiled kernel not work.
When you created your PKGBUILD did you by any chance forget to change its name? You should have something like "pkgname=linux-custom" (there's more to change, check the wiki for the full list) instead, so that your new kernel will be called "linux-custom" (or whatever you call it), and it can be installed alongside the (Arch) official "linux"
After that, you can put both in your bootloader, and boot the one you want. But yeah I think you definitely want to keep the official kernel alongside yours, just in case. -
Question about kernel compilation from wiki
Hello,
I compile kernel in line with arch wiki (http://wiki.archlinux.org/index.php/Ker … rom_Source). In paragraph '2. With makepkg and pacman (Recommended)' are lines:
mv [kernel location]/* src/
cp -r [kernel location]/* src/
Does it make sense? First I move [kernel location] to src/ (I think it should be '/src/') and then I copy nonexistent [kernel location] to the same path.
Thanks
#edit:
I looked through word 'either' So now I'm not sure with this:
(my build directory is ~/kernelbuild)
1. in ~/kernelbuild create 'src' directory
2. copy ~/kernelbuild/linux-2.6.30.5/* src/
Am I right?
Last edited by cinan (2009-08-22 12:16:34)Commands are correct, but as I said I was little confused about names/terms (eg kernel location-kernel source, making directory usr). I hope the wiki page will be more clear for users who never compiled custom kernel.

ATI display driver fails to work with new kernel
Hi,
I've just upgraded from
OEL kernel-2.6.18-194.11.3.0.1.el5.x86_64
to most current
OEL kernel-2.6.18-194.11.4.0.1.el5.x86_64
and got the problem with ATI display driver. Whenever I perform kernel upgrade, I have to recompile vendor-provided ATI display driver downloadable from AMD/ATI site, because system ATI driver, provided by OEL/RHEL as kernel module, doesn't work properly (too slow). I did that hundred times and never had a problem. This time the problem is that after upgrading to new kernel and recompiling the existing ATI display driver (Revision 10.8), it doesn't work anymore, even though it worked perfectly with previous kernel. I cannot even start X11 (glibc problem reported with stack traces!!!). The newest ATI display driver (Revision 10.9) "works" with new kernel, but display is awfully slow making any serious work impossible. It is even slower than system-provided ATI driver.
I am pretty sure the problem is in new kernel. As I have no backup of old kernel files and couldn't download the previous OEL kernel files from ULN, neither binary nor source (the files do not exist on ULN anymore, only the recent kernel files), I downloaded the previous kernel source from ftp.redhat.com, compiled the kernel and downgraded to it, recompiled ATI display driver, and everything works properly and fast as before upgrading. I can remember that ULN site used to have all kernel versions prior to actual one and cannot understand why Oracle dropped this practice. As I have an ULN account, I certainly want to have OEL patched kernel.
My question is: does anybody know how and where I can download the previous OEL kernel-2.6.18-194.11.3.0.1.el5.x86_64 binary rpm files or at least source rpm file?
Maybe Sergio or Tommy can help?
Thanks in advance.
NJI have experienced the same with Ubuntu some years ago - specific feature (hack?) that was implemented in the kernel was deprecated. This was used by the display driver for an onboard Intel graphics chipset. Beryl (which was subsequently merged with Compiz) turned into a horribly slow experience. As far as I recall, a subsequent kernel patch "fixed" things as a number of users were affected, of which many complained very loudly.
Anyway, I think the lesson here is that OEL is not really the correct distro to use for a desktop. A broken ATI driver for the OEL kernel? Does not really feature in the scheme of things for OEL support. Oracle Grid/RAC/Enterprise/Standard Edition do not care. Oracle's application servers (Apache, Weblogic, etc) do not care. Etc.
Sure, GUI desktop access to an OEL server is needed (like when running dbca or an installer) - but that can easily and effectively be done using vncserver for example and running twm.
You may be able to fix/work-around the problem with the current kernel update.. you may be able to roll back the update. But what about the next time when some other component does not work after a patch or an update? Surely it is a lot less stressful and frustrating to rather use a desktop distro, like Ubuntu, instead? -
A dozen+ Kernel Panics, suspect system issues - what to try?
Hello!
Well, in the last few weeks, my poor little Powerbook has lost its mind. I keep having Kernel panics for no apparent reason. Here's the story so far:
1. I upgraded to Leopard (archive/install) from Tiger, in November.
2. In early January, I had at least one kernel panic. Not sure what happened. By the middle of January, I had 3 or 4, and on (about) the 15th, I had three kernel panics in the span of an hour - and the lower ram card wasn't being recognized. I took it to the Apple store, where the tech said that it was the infamous "lower ram-slot issue" that plague my model Powerbook.
3. Once I got the powerbook back from the shop, it seemed to work quite well - fast, stable, panic-free. This week, however, I've had at least 6 or 7 kernel panics - at least 4 of them in the last 24 hours. A few of these weren't the usual "you need to restart your mac" window, but rather a long list of console-like text from the BSD subsystem itself
It seems to be related to the software - or perhaps Dashboard. Dashboard client has been running out of control this week - and started to go nuts about when the kernel panics started to occur. In fact, one of these "BSD" panics said that the dashboard client hung the computer. Thus, I moved all of my user (non-apple) widgets out of the library folder - effectively removing them from dashboard. This has prevented dashboard client from going nuts, but hasn't stopped the kenel panics. The ones that have occurred since seem to occur when using Safari or MS Word 2004, and one (another BSD panic) said that Window Server hung.
I've repaired permissions many times, used Disk Utility to verify the boot volume (it was OK), and zapped the PRAM and PMU - no luck.
I've had some other hardware and software issues:
First, Spotlight crashes when I attempt to search for something with a common name and have my 4 external hard drives attached... (One with Time Machine backups, one with other backups, and the rest with large volumes of video editing files). This issue probably isn't related to the kernel panic issue though, since it only occurs if I spotlight gets really bogged down - say, I search on "mac" and get 5000 returns...
Sometimes, if I have the power adapter plugged in and then boot up or wake the Mac, it sometimes won't recognize the adapter and thus run off battery. The solution? Unplug the adapter from the Mac and the wall, then plug both sides in. This occurs at least once a day, having become a much worse issue since sending it into Apple. This makes me think that I may have a issue with the power supply system in the Powerbook, and may be one of the causes of the panics. Again, zapping the PMU and PRAM, hasn't helped. Nor has deleting every power-related plist file.
The ram issue seems to have stopped, and I'm not sure the power issue could cause this - so I don't know what to do about this. It's happening a lot, but it's not exactly predictable - it would be difficult to reproduce for the Mac Genius, should I run to the Apple store. Since I suspect it's a software issue, I'm also not sure they can do anything about it. If Apple can't do anything about it, I plan on doing an Erase-install of Leopard, then carefully installing software - one thing at a time - to see if I can find the culprit. If worst comes to worst, I'll downgrade to Tiger...
So then, the questions, summed up are:
1. Do you have any idea what could be going on?
2. Can apple do anything about a software-related kernel panic issue?
3. If Apple can't fix it, and an erase-install won't work, when else can I try?
Sorry for the long post, and thanks a bunch for the help, I appreciate it.
-DanK, well i'll try to find the log on the backup clone I made - the Powerbook is currently in the Apple store for diagnostics. Hopefully, then can figure out what the deal is, but it will likely require an archive/install.
When I was there, he opened one of the logs in console - and it showed literally thousands of errors - all from "kernel". Wow, i have no idea what happened. He said that it may be bit-rot on the part of some of my applications, but there's probably not much they can do if it's not a hardware problem. sigh
Anyway, I'll look for the log on the backup volume when I get a chance. Thanks, I suppose you're right about you being forced to guess without the log. Didn't think about that... O:-) -
MacBook pro no longer starts after a month of kernel panics. What to do?
After about a month of kernel panics, my Mac crashed one more time and will no longer start. It sits at a black screen and just beeps, sometimes once, three times or more. I've been waiting for a friend to bring me an osx startup disk so I can fix it from the disk utility, but in the meantime I've been avoiding suspect programs as well as starting the computer holding command + s and typing /sbin/fcsk fy as many people have told me, and each time it said my hard drive was all right. My friend is coming back this week with the disk, but I am afraid it will be impossible even to boot from that. Does anyone have any suggestions? I don't have apple care or a warranty so going to the nearest apple store (one hour away) or the nearest servicer (a few minutes away) doesn't seem good. What should I do? I'm also slightly worried because I installed a firmware update not long before the panics started, to get around the region limitations of the DVD drive. I'm hoping this didn't cause any problems, since these panics seem to be related to RAM but the timing is just too convenient. Could this be a factor?
Thanks again BDAqua, and sorry for the long delay between reponses. The computer's been out of sight and out of mind for me the past few weeks, but my wife reminded meabiut it this morning.
So I tried the repair disk function within disk utility on the install disc, and everything seemed to be ok. I got a message in green that says "the volume Jeffs OW Mac appears to be ok." And then "Volume repair complete." I also noticed that the capicity of the drive appeared to be 119.69 GB and the available space 119.61 GB, which I guess meant the drive was completely empty but working.
So I tried once again to restore from my time machine backup, and wonder of all wonders, it worked this time! Two hours of restoration later, I'm writing to you now from the restored computer, and my wife is thrilled (and thinks I'm a genius!). So thank you thank you thank you for taking the time to walk me through the steps! I really appreciate it!
But now we're afraid to try again to upgrade to Snow Leopard. Do you think there's any reason trying again would throw the computer into another state of confusion, flux, and ultimately disaster, or should I just give it a shot? It's a 2009 Macbook Pro 2.2 GHz Intel Core 2 Duo, with 2GB 667 MHz DDR2 SDRAM, running OS X 10.5.8. Perhaps it just can't handle the new software?
All the best, and thanks so much again!

R12.1.1 certified with OEL 6.3? I failed to install on it.
Hi there
anyone could help shed the light for R12 installation problem on linux.

2. is it ok if I installed required OS library that newer than version in installation note ID 761566.1 ( e.g, in note requires gcc 4.4.4 I use 4.4.6 )?No, OS library mentioned in installation doc should be used.
autoconfig on DB and APP are completed, all listener completed, DB start but below 5 area failed RW-50015: Errorwhat is complete error in rapidwiz log. check below note for more on log location:-

Hey all,
I had made a post earlier about a seemingly random kernel panic that didn't have a specific task when panicking, and when I posted the error report I got a reply saying that it was a failure of a sata drive or in the controller. I use the OWC Data Doubler in place of my optical drive (have for years and it's worked flawlessly) and when I looked at it after receiving that comment, the connector ribbon that connects it to the logic board was ripped in two spots. I replaced that and still I am having kernel panics.
Can anyone see in the error report below to confirm if it is still a SATA device or controller, and if so, is there a way to find out more information as to whether it is the device or the controller? (or even if it's the 500GB 7200RPM drive in the HDD slot or if it's the SSD Data Doubler in the optical drive slot?

FireWire Device: My Passport 071D, WD, 800mbit_speedSo here's the deal, don't expect SATA III devices to work on the optical port. I just went thru this on both my 2009 and 2012 13" MBP's. The 2009 is SATA II (3Gps) and the 2012 is SATA III (6Gps). A SATA III SSD (OWC 6G) will only connect at 1.5 Gps on the 2009. On the 2012, it actually connects at 6 Gps, but every drive I tried crashed (dropped drives, file errors, kernel panics), including a Samsung 830 and Seagate Momentus XT 750. Out of desperation, I stuck the (slow 500 Gb) Apple HD in, it connects at 3 Gps and works like a champ. Check your System Info on SATA info. If you have a 2009, don't waste your $$$ on high end SSDs or drives. If you have newer, BEWARE, you're likely to have issues with high end SATA III devices. On the bright side both Samsung and OCZ V4 work great on the main drive (450 MB/s read) and boots in 10 seconds!! The optical drive SATA port is a major issue for everyone ( like me ) who buys MBPs because they can trip them out, this is a real nagging issue/obstacle. This is a firmware issue that needs to be addressed by Apple. I'm hoping for a firmware update and that Apple isn't doing this intentionally.

Hello.
I've upgraded to Snow Leopard from Leopard a couple of weeks ago, and I've read about the 64 bit kernel boot option, but I can't seem to get it to work (Software section in the *System Profiler* says "_64-bit Kernel and Extensions: No_").
Here is a rundown on the tech info of my mac:
% *Macbook Unibody* (bought at early 2009, before it was changed to be the Macbook pro) - MacBook5,1
% The output of "_ioreg -l -p IODeviceTree | grep firmware-abi_" says its EFI64
% I did an upgrade and not a clean install
% I tried holding down the 6 and 4 keys while booting (before the gray screen appeared) and the System Profiler still showed that it's not a 64 bit kernel
% I changed my /Library/Preferences/SystemConfiguration/com.apple.Boot.plist file to have:
*<key>Kernel Flags</key>*
<string>arch=x86_64</string>
and still no 64 bit kernel according to system profiler.
% I installed all the updates from apple (currently at 10.6.2)
% The Extension section in System Profiler lists the following as NOT 64bit:
$ BSDKernel6.0
$ CHUDKernLib
$ CHUDProf
$ CHUDUtils
$ IOKit6.0
$ Libkern6.0
$ Mach6.0
$ System6.0
So - why is it not booting 64 bit kernel, and how can I fix it/make it boot 64 kernel ?
All the tech info shows it should do it (except maybe for the listed extensions which are not 64bit, but there's not reason that they won't be, if I did a normal upgrade to Snow Leopard, the efi is 64, and other users with the same details can boot 64 bit kernel).
Thank you very much for any help!welcome to Apple discussions, gshockoman !

[solved] kernel configuration for clarkdale server
Update: I guess since the arch kernel config works there's really nothing to improve.
Hey everyone,
i'm about to compile a kernel for a server with intel clarkdale hardware, intel i3-530.
Up to now i only compiled kernels for my consumer laptop.
1) Is there any option in particular i should pay attention to when compiling a kernel for a server system?
And regarding the i3-530:
2) Should i just pick x86 generic cpu support or something else?
3) Are there any patches right now to improve support for clarkdale?
Thanks,
demian
P.S.: I guess i should choose 2.6.33-rc7 since real clarkdale support is supposed to come with 2.6.33? Usually i just pick the latest stable version.

thanks for your rapid response and i googled about it, but unfortunatelly i dont have a gigLan in the lab but usually all file transfered exceed 5GB of size.
Would the scheduler have a significant impact on performance? The servers are used individually (not sharing load like in a bewoulf cluster)
The disk I/O operations are mostly about writes into the output files (a few number of bytes per write), would reiserfs be superior to ext3 ?
PS.: i'm feeling really stupid for not reading more about the kernel26-lts for it has all the major options i was thinking about.

I'm just wondering what's up with the RAM usage on my macbook. Right when I start up 500MB of RAM is being used (wired and active), 100MB of it being the kernel task. After a typical session of use, I close all programs and find that the RAM usage is about 800MB and the kernel task is using 250MB. Just wondering why the kernel task's RAM usage creeps up like that and doesn't go back down. It's just a little perplexing to have the same exact programs running and be down 300MB of free RAM.
I was having the same problem and looked into it, this may help:
