Multi Processor? Only 1 out of 8 cores working

I checked the preferences. Don't see any options to
distribute the processing. Jobs take forever but have the untapped
potential for a big speed boost.

Please share your encoding settings and machine
configuration. Are you using FMLE 3.0 version?
What was the overall CPU usage for the FMLE process and what
was the distribution of CPU usage across the different
cores?

K9N2 SLI Platinum, only 4 out of 6 Raids work

Hi,
I recently got this K9N2 Platinum Board running with AMD X2 5400+ and 8GB of Corsair Memory. I am wondering why there are only 4 out of 6 SATA channels listed in the Bios? I have 4 Hard Drives (not raided) and one DVD-ROM that is connected to SATA5. I also did a switch to SATA6 and the Bios still does not show up the other two SATA channels.
Can someone please help me with this problem? I have been hitting a brick wall for awhile
Thanks

Hello!
Please say more about your system.
Mod: From the manual: "2. SATA5 & SATA 6 support AHCI mode and RAID mode only." P2-13
If you have a PATA DVD you can use that. Set DMA transfer to UDMA2.

Arch only detecting 1 CPU 1 core instead of 16 processors

EDIT:
It turns out it was a BIOS problem. I flashed to a different BIOS and reset everything to default settings in the BIOS, and now all 16 processors are recognized.
I have a system with an Asus Z8PE-D18 motherboard with 2 Xeon E5520 CPUs. Each CPU has 4 cores and 8 threads, so linux SMP should see 16 processors. But my recent Arch linux install only sees 1 CPU 1 core. Is this a kernel bug, or is something not configured properly? I have another similar machine running Ubuntu that sees all 16 processors, and the only difference I see offhand is that uname -a gives "SMP" but not "SMP PREEMPT" as shown below. Is that significant?
I'm new to Arch linux. What is the best way to try a different kernel without compiling it myself? Any suggestions on a kernel package to try?

Multi-Processor Performance

I would like to know what performance gains I might expect from moving our
weblogic application server to a multi-processor machine. Will 2 processors
handle twice server the load of the one processor machine?
Platform: Solaris 2.6
Weblogic Server: 4.5.1 SP7
NativeIO enabled
Weblogic Server is the only thing running on the machine.
Other Questions:
1. Is there anything that needs to be done(other than purchase another
license) for the weblogic server to work on a multi-processor system?
2. Will the weblogic server naturally take advantage both processors?
3. Will performance gains be uniform or will certain features gain more
from multiple processors?
Any links or suggestions are appreciated.
thanks,
Jeremy

Hi Jeremy -
If you are interested in modeling this before implementing it to determine
performance gains, you might want to check out our scalability assessment
services description, see attached. We are a BEA Technology Alliance Partner
that specializes in answering those specific performance questions, and have
done that for a number of clients in the past few weeks.
(See also eQASEsheet2.pdf) - this describes our capacity sizing tool that works
particularly well for Weblogic.

Right people, I really hope you can help... here's the story:
I produce with a friend and approx 4 months ago we both upgraded to brand new MacBook Pro's each and Logic Pro 9 each.
I bought a 13" MacBook Pro with 4GB and the 2.53Ghz Intel Core 2 Duo processor.
He bought a 15" MacBook Pro with 4GB and the 2.66Ghz Intel Core i7 processor.
We both have bought the full version of Logic Pro 9, both done the upgrade to 9.1 and have both set our copies of Logic to 64 bit.
Why? The only advantage you have from 64 bit is that Logic can use more than 4 GB RAM - which neither of you have. I would strongly recommend setting Logic to 32 bit. On both Books. It might alleviate some or even all the problems - I hope.
Here's a list of unavailable features in 64 bit mode:

My friends copy of Logic on his Mac is so buggy its sometimes unusable.
My mate is about to throw the **** thing out of the window and buy Cubase!
More often than not it is hard to install new software on computers that have been thrown about.
Can anyone shed any light please??
I think 32 bit is your answer. However, the mobile i7 processor does at least have one issue with Logic:

Multi-processor support!

I must say that the only feature that will make me upgrade ever again from CS4 (or even to upgrade my MacPro) would be full multi-processor support.
Unfortunately, Adobe has been introducing new features that turn out to be imperfect and NEVER get updated or fixed any more.
Hoping for CS5 to come through!

You're right. What I meant was FULL multi-processor support.
Like saving and opening files, especially when saving large, multi-layered 16 bit files. Just tested it again - a file that is 2.91GB when opened in photoshop (which any file I work on typically is) takes 42 seconds to save as an 8 bit file and (after deleting layers to make it the same 2.91GB when open in photoshop in 16 bit format) takes 5min and 20 seconds to save in 16 bit while the activity monitor shows only one processor being utilized.
I would like to work more in 16 bit but it's not practical now as it takes too long for just the saving part.
At least it should be non-modal so that you could work on another image while others are being saved and/or opened.
There are also a few filters that do not use multiple processors - like the lens blur filter, which works amazingly well but makes me take a coffee break every time I use (especially when used with a large blur amount).

Only using 1 of 4 cores ?

Hi
Everytime there is a high processing app running at max, it seems to use all of one core block on Activity Monitor, but the rest of the 3 remaining cores are empty. AM shows 100% cpu and things dont get any better if i open another app alongside - it just detracts from the one processor being utilised at any one time.
It just seems that i dont get the benefit at all of the 3 redundant cores ?
is there any way i can change a setting to get more cores working all the time instead of one maxing out at a time ?
cheers

Applications must be written in multi thread to spread across multiple cores, single thread application, like QT I think, will always run on one core. I don't know why, off hand, running more applications will not use more cores, perhaps an OS issue.

Oracle on dual-/multi- processor server

I have a question regarding Oracle on dual (or multi) processor servers. I have purchased 2 copies of the standard edition. I installed it on the server with 2 processors.
My question is whether or not there is something different in the installation for multi processors.
Another question would be if it is possible to install the database on a dual processor, if you only have a single copy of the license.

The licenses are acquired by CPU or by users and you acquired the license for only 1 processor you must not install it on a server with 2 processors. Your enterprise can have legal problems if that situation occurs.

Concurrency in Swing, Multi-processor system

I have two questions:
1. This is a classic situation where I am looking for a definitive answer on: I've read about the single-thread rule/EDT, SwingWorker, and the use of invokeLater()/invokeAndWait(). The system I am designing will have multiple Swing windows (JInternalFrames) that do fairly complex GUI work. No direct interaction is needed between the windows which greatly simplifies things. Some windows are horrendously complex, and I simply want to ensure that one slow window doesn't bog the rest of the UIs. I'm not entirely clear on what exactly I should be threading: the entire JInternalFrame itself should be runnable? The expensive operation within the JInternalFrame? A good example of this is a complex paint() method: in this case I've heard of spawning a thread to render to a back-buffer of sorts, then blitting the whole thing when ready. In short, what's the cleanest approach here to ensure that one rogue window doesn't block others? I apologize if this is something addressed over and over but most examples seem to point to the classic case of "the expensive DB operation" within a Swing app.
2. Short and sweet: any way to have Swing take advantage of multi-processor systems, say, a system with 6 processors available to it? If you have one Swing process that spawns 10 threads, that's still just one process and the OS probably wouldn't be smart enough to distribute the threads across processors, I'm guessing. Any input on this would be helpful. Thank you!

(1) You need to use a profiler. This is the first step in any sort of optimization. The profiler does two important things: First, it tells you where are the real bottlenecks (which is usually not what you expect), and eliminates any doubt as to a certain section of code being 'slow' or 'fast'. Second, the profilter lets you compare results before and after. That way, you can check that your code changes actually increased performance, and by exactly how much.
(2) Generally speaking, if there are 10 threads and 10 CPU's, then each thread runs concurrently on a different CPU.
As per (1), the suggestion to use double buffering is the likely best way to go. When you think about what it takes to draw an image, 90% of it can be done in a worker thread. The geometry, creating Shapes, drawing then onto a graphics object, transformations and filters, all that can be done offline. Only copying the buffered image onscreen is the 10% that needs to happen in the EDT thread. But again, use a profiler first.

Multi-processor Multi-Threaded deadlock

Hi all-
I've posted this over at jGuru.com and haven't come up with an effective solution but I wanted to try here before I reported this as a bug. This deals with kicking off many threads at once (such as might happen when requests are coming in over a socket).
I'm looking for a way to find out when all of my threads have finished processing. I have several different implementations that work on a single processor machine:
inst is an array of 1000+ threads. The type of inst is a class that extends threads (and thus implements the runable interface).
for (i = 0;i<Count;i++)
inst[ i ].start()
for (i = 0;i<Count;i++)
inst[ i ].join();
however this never terminates on a multiprocessor machine. I've also tried an isAlive loop instead of join that waits until all threads have terminated until it goes on. Again, this works on the single processor but not the multi-processor machine. Additionally someone suggested a solution with a third "counter" class that is synchronized and decremented in each thread as processing finishes, then a notifyAll is called. The main thread is waiting after it starts all the threads, wakes up to check if the count is zero, and if it's not it goes back to sleep. Again this will work on the single processor but not the multi-processor.
The thread itself ends up doing a JNI call which in turn calls another DLL which I just finished making thread safe (this has been tested via C programs). The procedures are mathematically intensive but calculation time is around half a second on a P3 800Mhz.
Any help on this is greatly appreciated. My next step will likely be tearing down the application to exclude the calculating part just to test the JVM behavior. Is there a spec with the JVM behavior on a multi processor machine, I haven't seen one and it's hard to know what to expect from join() (joining across to processors seems like wierd concept), getCurrentThread() (since 2+ threads are running at the same time), etc.

My next step will likely be tearing down the application to
exclude the calculating part just to test the JVM behavior.Sounds like a really good idea.
Is there a spec with the JVM behavior on a multi processor machine, The behaviour of threads is defined in the specs.
You might want to check the bug database also. There are bug fixes for various versions of java.

Multi processor Solaris 2.6 and mutex locks

hi,
is anyone aware of any documented issues with Solaris 2.6 running
on dual-SPARC processors (multi-processor environment) where the
programs using "mutex locks" (multi-threaded applications), require
some special handling, in terms of compiling and linking, to some
special libraries.
as far as i remember, in some OS book, maybe Peterson's, it was said
that the mechanism for implementing mutex-locks on multi-processor
systems is to use low-level spin-locks. this brings down performance
on a single-processor system, making the processor doing busy-wait,
but this happens to be the only way of mutex-locking in a multi-processor
system. if this is so, then where is such behaviour documented in case
of Solaris 2.6.
i have had problems with my applications crashing (rathing hanging up)
in a vfork() on such a system, but same application works fine, with
100% reproducability, on a single-processor system.
thanks for any inputs or suggestions and/or information.
regards,
banibrata dutta

I am also facing similar problem. Application which written using Mulit-Threaded using Posix Mutexes. When i run on SINGLE processor manchine, i.e.
SunOS sund4 5.7 Generic_106541-11 sun4u sparc SUNW,Ultra-5_10
It works perfectly.
But when try to run on dual processor machine, i.e.
SunOS sund2 5.7 Generic_106541-11 sun4u sparc SUNW,Ultra-250
It is blocking in the one of mutexes.
Please inform us what is problem. Mr. B. Datta, you comes to know
any channel, please inform me also at [email protected]
Thanx & regards,

Advantages of multi processor systems?

I am considering getting a new system to use for my photo processing applications. I see that Adobe has releases LR v2.0 which supports 64 bit OS and has announced that CS4, when ever it is released will also support 64 bits, well at least for Windows. This being the case, switching to Vista 64 seems to be the way to go. BUT what about the processor? The choices seem to be a quad core version from either Intel or AMD or moving higher, a Intel Xeon processor. This gives me two more choices, use two 5100 series processors for a total of four cores or go up to two 5400 series processors for a total of eight cores. The 5100 series approach seems to use less power that the 5400's and can be clocked faster. Also, last year I had the opportunity to quickly run a bench mark with CS3 on a Dell dual Xeon workstation running Windows XP 32 bit OS. It appeared that the the system only managed to make use of only 4 of the 8 processors.
I have done a fair amount of searching and have not found any good answers to the question of which processor configuration will give the best performance. To keep this discussion reasonable I would like to limit it to one quad core processor vs. two dual core Xeons vs. two quad core Xeons.
Hopefully some of you will be able to shed some insight. It any of the Adobe folks would care to comment, it would be appreciated. I suspect that Adobe has looked into this issue and has lots of information. The question then would be can they share it? Maybe not.
Bill

I run a Xeon Quad Core 2.33GHz at work and a Core 2 Duo 2.66GHz at home. Both are very fast, but the Xeon Quad Core is significantly faster. Is it a difference between going home at 5:00 vs. 6:00? Nope, more like 5:00 vs. 5:10 at best. But it does make the workday more pleasant.
I would go with Vista 64, 8GB (or more) of RAM and something like a Core 2 Quad Q6600. Pop a $40 cooler on that bad boy, overclock to 3.0+ GHz and watch it fly. For more fun, get a Skulltrain motherboard and add a second CPU when your apps can take full advantage of 8 cores.
And install an nVidia 9800GX2 graphics card - CS4 is supposed to take advantage of advanced GPUs.

CPU time from a multi processor

Hi
I need to get the CPU time from a multi processor machine,
The top command will not do the job for me, and I will need to use the command in automation for testing the CPU time for 2 hours or more, I thinking about redirect the CPU % to a file, and in the end I will run the average for the numbers in that file.
If I will be able to see the CPU time for the two processors it will be grate, but more important is to collect the global CPU status.
I don�t have a command line that a can use, I can use some help.
Thanks Shay

WLS on Multi-Processors

A few questions about WLS 5.1 on multi-processor machines:
1. Is there anything that needs to be done(other than purchase another
license) for a weblogic server to work on a multi-processor system?
2. Will WLS take advantage of all processors with just ONE invocation of WLS?
Or will I have to run one instance of WLS for each processor?
3. Will performance gains be uniform or will certain features gain more
from multiple processors?
Any answers, insights or pointers to answers are appreciated.
Thanks.

Rob,
I consider WebLogic to be a great no-nonsense J2EE implementation (not
counting class loaders ;-). Gemstone's architecture is quite elaboratewhen
compared to WebLogic, and BTW they spare no opportunity to compare to
WebLogic although never by name. (Read their white paper on scalabilityto
see what I mean.) I am quite impressed by their architecture; it appearsto
be set up for dynamic reconfiguration of many-tier processing. Forexample,
where WL coalesces (i.e. pass by ref if possible), Gemstone will always
distribute if possible, creating a "path" through (e.g.) 7 levels of JVMs
(each level having a dynamic number of JVMs available in a pool) and if
there is a problem at any level, the request gets re-routed (full failover
apparently). I would say that they are set up quite well to solve the
travelling salesperson problem ... you could probably implement aweb-driven
neural net on their architecture. (I've never used the Gemstone product,
but I've read about everything that they published on it.) I would assume
that for certain types of scaling problems, the Gemstone architecturewould
work very very well. I would also guess that there are latency issues and
administration nightmares, but I've had the latter with every app server
that I've ever used, so ... $.02.

However, out of curiosity, what are their reasons?
Anyway, here is my question:
why running multiple instances of WL is more efficient than running
one
with
high execute thread count?The usual reason is that most garbage collectors suspend all of the jvm
threads. Using multiple WLS instances causes the pauses to be
staggered. Newer java vms offere incremental collectors as an option so
this may no longer as big of an issue.

Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say. It will shut down if it gets too hot, but that's not a normal occurrence. I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
First thing I would try to do is reset the SMC. If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
If a fresh system doesn't help, you'll need to get it checked out by Apple.
Edit: Oh, and sig is absolutely right... please don't post in all caps! It's very irritating.
