OL5.8 OVM Guest number of CPU´s

Hi,
does anyone can help we understand if it is possible and a good idea to configure more virtual CPU´s
in a OVM Guest as cores integrated in the physical hardware.
We have a 2 cpu 6 core OVM hardware and try to configure 20 virtual cpu´s in ONE guest system.
I don´t like that idea....
Thanks *T

..So xm info told me that
release : 2.6.18-128.2.1.4.44.el5xen
version : #1 SMP Thu Nov 10 22:05:12 EST 2011
machine : i686
nr_cpus : 16
nr_nodes : 1
cores_per_socket : 4
threads_per_core : 2
So we have 16 cores inclusive Hyper-Threading or 16 cores *2 ?
cat /proc/pcuinfo
rocessor     : 15
vendor_id     : GenuineIntel
cpu family     : 6
model          : 44
model name     : Intel(R) Xeon(R) CPU E5640 @ 2.67GHz
stepping     : 2
cpu MHz          : 2665.912
cache size     : 12288 KB
I´m confused :-/
Oracle Support told us to set the vCPU´s to 20 because of we have 10 intances on on OVGuest....
Thanks *T

Detecting number of cpu from kernel

Hi, how do I detect the number of cpu in kernel mode?

This prints the number of procs.
main()
long procs;
procs = sysconf( SCNPROCESSORS_CONF );
printf("Processors Configured =%d\n", procs);
procs = sysconf( SCNPROCESSORS_ONLN );
printf("Processors Online =%d\n", procs);

Flash Media Server 3.5/number of CPU

How many number of CPU cores Flash Media Server 3.5 supports?

Hi,
You could refer to the EULA located at the FMS install directory/License.htm.
So in short to install FMSS you could use up to 4 CPUs and to install FMIS you are allowed to use upto 8 CPUs.
The section 2.8.5 states:
2.8.5. License Limit. Licensee shall only use the Software corresponding to the licenses for the Software that Licensee has purchased. Licensee is permitted to install the Streaming Server on a single Computer or Virtual Server containing up to 4 CPUs. Licensee is permitted to install the Interactive Server on a single Computer or Virtual Server containing up to 8 CPUs. In the event that Virtual Servers are installed on a Computer, each such Virtual Server shall be deemed to operate the Software on 2 CPUs (each, a “Virtual Server CPU”), and the total number of Virtual Server CPUs plus the total number of physical CPUs on such Computer, shall be counted together for the purpose of applying the limitations set forth in this Agreement. For all the Software licensed hereunder, if Licensee exceeds the limitations set forth herein on a single Computer or Virtual Server Licensee must purchase another license to the Software, and such additional license shall permit up to permitted number of additional CPUs (including Virtual Server CPUs) in such Computer or Virtual Server.
Thanks

Number of CPU - Solaris SunOS 5.9

Hi,
can someone tell me how can I figure out the number of CPUs in SunOS 5.9.
I executed
psrinfo -p and the result was 8.
Then I ran
psrinfo |wc -lthe result was 12.
I'm not an expert in Unix, can one tell me what is the right command ?
Thanks.

Hi, thanks for the reply,
In order to use parallel degree in move and rebuild segments reorganization , should I consider physical number of CPUs or the core too ? I guess I shuld use just Physical CPU, is it correct ?
If both source & destination reside on same physical disk volume, little will be gained by throwing CPU cycles at the problem.
Disk I/O saturates faster than CPU or RAM does

Number of CPU Count

Dear all;
This is regarding Solaris v10 x86 AMD64
Can anybody tell me that by default free downloaded o/s supports maximum how much CPU count.
And ref. document link for the same.
Devang Modi

In the forthcoming version of J2SDK 1.5 there will be a package named java.lang.management, and an interface called OperatingSystemMXBean. One of its methods returns the number of CPUs available to the instance of the JVM running.
It depends on the processor count reported by the operating system. If you have a Pentium 4 with hyperthreading enabled your operating system reports 2 "logical" CPUs although you know that you have just only a physical CPU chip in your machine. As I haven't tested the "getAvailableProcessors" method in a HT machine I can't say exactly the result, if the getAvailableProcessors returns the number of logical CPUs or physical CPUs.
(Obviously if you have a machine with 32 CPUs but you're running in a "domain" or a "virtual machine" that do not expose all CPUs to your process, or if some of the CPUs are disabled (it's a common fact among IBM server machines - the CPU chips are physically present, but don't work - just pay for the additional CPUs and they will unlock them), the JVM will report a smaller number. It depends in the hardware.)
public interface OperatingSystemMXBeanThe management interface for the operating system on which the Java virtual machine is running.
A Java virtual machine has a single instance of the implementation class of this interface. This instance implementing this interface is an MXBean that can be obtained by calling the ManagementFactory.getOperatingSystemMXBean() method or from the platform MBeanServer method.
int getAvailableProcessors()
Returns the number of processors available to the Java virtual machine.

OVM Guest wrong hardware clock

Hi,
I'm running an Enterprise Linux 6.3 (PVM) on an OVM host.
The problem is that the date in the EL guest doesn't correspond to the date in the OVM host. The time in /var/log/messages is skewed: it's 6hours too early.
The hwclock on the host:
[root@lnx-iaovm01 /]# hwclock
Fri 17 May 2013 10:53:51 AM CEST -0.737400 seconds
Output of the command on the guest:
[root@lnx-ianag01 vm]# hwclock --debug
hwclock from util-linux-ng 2.17.2
hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.
No usable clock interface found.
Cannot access the Hardware Clock via any known method.
I tried the following solution: ln -s /dev/rtc0 /dev/rtc
but I don't have a /dev/rtc0 directory so this isn't very successful
I also tried setting my TZ in my /etc/profile (so the "date" command atleast is correct but since this is just an environment variable so it doesn't really help either).

Isn't it easier to just enable ntp to sync your VM with a clocksource locally in your network or on the internet?

Detecting number of cpu from the driver

Hi, my driver needs to know how many cpu are there on th computer for optimization reasons.
How can it be done??

This prints the number of procs.
main()
long procs;

printf("Processors Configured =%d\n", procs);
procs = sysconf( SCNPROCESSORS_ONLN );

Alter number of CPU's used by Solaris

Regarding a performance test being done on some databases running on Solaris 10, I'd like to alter the number of CPUs being used by the system. Currently there is 4 CPUs available and all are used, but I'd like that only 2 of them are to be used. (Physically removing the CPUs is not an option:))
Is this possible, and if so: how?
Thanks in advance :)

You can offline 2 of the 4 CPUs.
Check out psradm(1M).
Hope this helps.

What is the optimum number of CPU cores for Photoshop CC?

The title is the question.

To reinforce what Chris has said, keep in mind there's only one processor package in the new Mac Pro. There are cases where having two packages - such as in the previous design Mac Pro with dual Xeon x5600 series processors - can actually be a pretty big advantage.
That being said, I've put a lot of thought into how many cores a new Mac Pro ought to be configured with to run graphics software well, and I've come to the thought that 4 is too few and 12 is way too many. I believe the 3.5 GHz 6 core E5-1650v2 may actually have a slight edge over the 8 core E5-2667v2, because with 12 logical Ivy Bridge processors cranking full-on (with Hyperthreading) the memory bandwidth is actually already going to be taxed. And of course the 6 core is much cheaper.
There's a nice little Photoshop benchmark that's reasonably indicative of how well a system actually multithreads with Photoshop. It can be found here:
http://ksimonian.com/Blog/2010/02/24/improved-photoshop-benchmark-cpu-speed-test-for-both- mac-pc-free-radial-blur-filter-test/
I have a PC workstation with the same chipset as the pre-cylinder Mac Pro (dual Xeon x5690s in my case), and my best speed for that benchmark with Photoshop CC equals the best posted on that site: 8.3 seconds. People are reporting the new Mac Pro is scoring with that benchmark in the same vicinity - but not really faster.
Do some research yourself and see what various folks with the new cylindrical Mac Pro are scoring on that benchmark. I'd be interested to hear if your findings are like mine.
What's your system score, Chris?

How to set number of CPU usage at Virtual PC

Hi all,
After review below:
http://support.microsoft.com/kb/824355
I am not able to find Preference in Virtual PC manual. May i know how to set CPU usage on Virtual OS.
Many thanks.
Regards
Andrew

Hi,
Each Virtual Machine can make use of only a single processor at a time. This is by default. if you mean that you want multiple virtual CPUs assigned then you need to look at an alternative VM system such as Hyper-V.

How to size number of cpu after physical to container?

Dear all,
I am new to Solaris container. Now I plan to migrate several old solaris host such as E4900 running solaris 9.
Consolidating them into solaris 9 containers running in SPARCT4-4.
Sun Fire E4900 Sun Sparc 16cpu 1375MHz
New T4 4 x T4 cpu (each cpu 8 core, each core 8 thread) => 256 vpcu, each running 3GHz
It does not make sense that we assign 16 cores of T4 to new solaris 9 container. And E4900 and T4-4 are different CPU models. How can I match them?
Have any one good idea upon this?
Many thanks,
Mike Tang

what type of workload do you have from the old system side? lots of single threaded apps? db server? some of how you could size it may depend on licensing models, if any, you may have to deal with. some restrict based on cpu count/core count/socket count so that can quickly make your target cpu assignment.
example we had: sun 280r to a zone on a t4-2. capped the cpus for the zone based on our oracle licensing from the old sys.

How JDK support number of cpu

I write a Java Application to access DB.when I run this Java Application on a 2-CPU Windows Platform with JDK 1.4,It uses 5s.But when I use JDK 1.5,It only use 2.8s.How does this occur???
Does JDK1.5 support better for more CPU??
Best Regards

Java 1.5 has many performance enhancements compared to previous versions, it's not specifically because Java 1.5 knows how to handle multiple CPUs better.
See this part of the JDK 5.0 release notes:
Improvements to Program Execution Speed - Enhancements in JDK 5.0

How the Performance data depends on Number of CPU/ RAM size/ Hard Disk size

Hi,
I have started Performance testing (web test and Load tests) using VSTS 2012. I was analysing the VSTS results summary page.
I could not find a way by which we can find a co-relation between the Performance Result data Impacted by Server's Configuration such as
1- # of CPUs /Cores
2- RAM size
3- Hard Disk capacity
Could you help me out if we can reach to a point, through which we can say that, For eg - the Server Performance can be improved if we increase any of the dependent hardware configuration and Also, How the Hardware configuration impacts the Performance.
Thanks.
Thanks, Anoop Singh

The results show the performance with the hardware and software configuration
when the test is run. The results may show that some parts of the configuration are lightly loaded (and hence have plenty of spare capacity) whereas other parts are heavily loaded (and hence may be limiting the system performance).
To see the effect of changing the hardware or software configuration would need running exactly the same test with that changed configuration. Then the results of the two (or more) different runs can be compared. Microsoft has some details on how
to compare load test results. See
