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?

Only one CPU core recognized [solved]

For some reason the kernel only recognizes one CPU core out of two. I'm not completely sure at which kernel upgrade it disappeared but it is gone in 2.6.36 and 2.6.37. I know it was still there in september 2010 and earlier. I'm using a x86-64 kernel.

Motherboard is: Gigabyte MA770T-UD3P. I use the latest bios.
I have tried adding the kernel options "acpi=off noacpi apic=off noapic" as to the suggestion of a ubuntu bug report in launchpad but it didn't help. I also disabled ACPI in the bios but I'm still limited to one cpu core.
Any ideas?
[SOLVED]
I just doublechecked the BIOS settings and it had the CPU Core Control set to manual and one core was disabled. I set it to auto again and now both cores are recognized correctly. I don't recall ever touching this setting but at least it works now. Maybe a bios update actually changed the setting or (more probable) a friend of mine.

Webform loading too long : only 1 cpu core used out of 16 core available?

Hi,
We have one webform which is quite heavy and takes 1min30 to load :
1 minute for essbase calculation (spreadsheet extractor)
30 seconds for network & browser rendering
We have seen that Essbase is only using 1 cpu core (100% usage) out 16 core available
Does it is possible to give some calculations to other cpu core? I know it's possible for HBR rules with CALCPARALLEL but for a webform?
Thanks!
Edited by: Tipiak on 3 juil. 2012 23:06

The system has no ability to use multiple threads for one web form. It sounds as if your form is not designed for optimal performance which usually means you have a large number of total cells and/or are not using dense dimensions for your rows and columns (usually accounts/periods).
Suggest you refer to the KB article which discusses Hyperion Planning Form design at:

Database uses only one cpu core from 16 available

Hi,
we have an server with 16 CPU cores, and we discovered from em that it uses only 1 core with 100% and the others are idle.
the initialization parameters for CPU are:
cpu_count 16
parallel_threads_per_cpu 2
resource_manager_cpu_allocation 16.
What can we do to use all 16 cores.

Very interesting poit of view, but since I have for some period of time 1 core on 100% and other cores are idle or 0%,
I don't think that we can say that linux and oracle database 11g is using the best from that server, can you?Well, I did not offer a point of view. I offered fact - a reason why on x86 architecture it is faster to keep threads on the same CPU (if sufficient CPU capacity) then run such threads across CPUs.
As for what you are seeing - we cannot see it. So the only data we have is what you offered. And that does not suffice in making any kind of call as to why you are seeing, or even describing the symptoms correctly.
Why don't you try another example? 3 client server applications. Each client post a request (huge update 100% CPU, small update 0% CPU, huge select 100% CPU). What the server does, it switches between those 2 huge requests an uses only one core on 100% abd the others 15 are sleeping. Why don't use each request on different core and reduce the time?Define "+huge request+". Database operations are typically I/O intensive - not CPU intensive. There are also a number of processes. So if PMON for example is showing high CPU, then that means something different as when DBWR is showing high CPU, versus a dispatcher process showing high CPU.
So you need to provide a lot more detail for us to speculate as to what the problem could be, never mind offering a solution.

Only one CPU core is working during video export from Premiere Media Encoder

Windows Resource Monitor showed cores 'parked' at first. I was able to turn that feature off using regedit. They no longer say they are parked'. but still only one core is at 100% while the other seven cores are at close to zero %. Windows 7 Ultimate SP1 64-bit. i7-2600k processor 3.4 GHz running at 3.8 GHz XMP setting. ASUS P8Z77-V motherboard 32 GB RAM.
I had this problem in the past and fixed when I turned off core parking. But, I recently clean installed Windows and problem has returned. I contacted Microsoft and they assured me that the problems lies with Premiere or AME.
it just took over an hour to export a video that should have taken 10 minutes

This has been driving me CRAZY... so going over the message boards from 2 to 5 am this morning I found the best explanation I have seen. The problem is that Adobe Creative Cloud is NOT "Processor Group Aware". Windows parses any more than 36 cores into "Processor Groups" and while the Pro version of Windows 7 & 8 can handle 256 threads they have to spread them across multiple processor groups.

Photoshop CC only detects Intel GPU instead of AMD Radeon (Win8)

Hi,
I am running a pc with Win 8 and Intel i7-3630QM CPU.
On my system I am running 2 Video Cards, both Intel HD Graphics 4000 and AMD Radeon HD 7670M.
I set my switchable cards to high performance when using photoshop.exe, but when I check in PS Preferences, the detected Graphic Processor is Intel HD 4000.
How can I set my AMD radeon for higher performances?
Thanks
Cecilia

With dual-GPU's, it is often necessary to disable the Intel GPU, usually in the computer's BIOS.
Many laptops have dual GPU's, to allow them to run with low power consumption (on the Intel), and then they automatically switch to the AMD/ATI, or nVidia GPU, depending on which chip is installed, for more graphically intensive work. That often works well, but not in all cases. In most of those anomaly instances, the switching in the BIOS takes care of the issue - inconvenient? Yes, but often necessary. Some users have had good results by disabling the Intel in the OS's Control Panel, rather than at the hardware level with the BIOS.
Good luck,
Hunt

Flashed both BIOS chips or just one? If you flashed only the A chip, power down, manually switch to the other BIOS chip and test. Code 00 in the AMI code chart reads it is for future use or something like that.
No, you don't have to flash an in between version, you can always go to the very newest and skip earlier ones.

4 virtual CPUs are how much physical CPU core

Hi Everybody,
I've two VMs with 4 VCPU per VM.
First VM is created on VMware the second VM is on Oracle Virtual Server 3.1.1.
The VMware server is on the same HW architecture as Oracle VM Server (two blade as twins).
I've created Oracle database server 11gR2 on both VM.
The Enterprise Manager Cloud Control "Database - Performance Home" page shows 4 CPU Cores in case of VMware VM,
but only 1 CPU Core in case of Oracle VM.
I'd like to understand why.
Help me please.
Regards,
Battila

Did you set processors and the max processors the same on the VM guests?
One CPU is one CPU core. If you do not use CPU pinning..... CPU core allocation is load balanced across all cores in the system. When you use CPU pinning. (Which you must do in a oracle database to adhere to licensing requirements where they apply) CPU cores are dedicated to the VM guest and not load balanced. You can overcommit CPU resources in Oracle VM. In other words. You can set max CPU across all VM guests on a single VM server to be greater than the total amount of CPU cores available in the system. Check out article 464754.1

AE CC not using 4 CPU cores

I have Win8 Pro 64-bit version and AE CC 64-bit, RAM is 16GB. Processor is Intel i5 2500k, 4 cores.
And in my task manager I see AE is using only 2 cpu cores, why isn't it using all 4 of them for rendering?

See this to understand how CPUs are used by After Effects:
https://www.video2brain.com/en/lessons/optimizing-cpus
You won't always see all of your CPUs used at 100%. There are a lot of other components to rendering, and the CPU is often not the bottleneck.

no offense but how should i know that you don't have one more comp at home.
what was the previous problem you had with the mobo for which you needed a BIOS update?

CPU Meter in transport only showing 2 cores

Ever since the 9.1.2 update, the CPU meter in the transport bar is only showing 2 cores (I have 8 cores). However, if I option-x to see a floating CPU and HD window, all 8 cores appear. Anyone else with this problem?

Addenddum:
I only see 1 load-bar in the transport CPU-meter. Its amplitude is the amplitude of the heaviest used core, but there also is a thin yellow line within the one bar showing the average load over all cores (I think).

Multisim 11 only uses one CPU core during simulation

Hi,
Just recently I've been using MultiSim again, v11 if that matters, and simulating goes slow, to my opinion that is.
Now there are two things that I've noticed:
- Multisim only uses one of two CPU cores during simulation, not both;
- I've enabled CPU throttle (AMD's Cool'n'Quiet) but corespeed remains very low even though Multisim needs CPU power while simulating.
The simulating of a NE555-based LED-flash circuit requires about 28 seconds to get to 100ms in the simulation. Now if I can get the CPU to throttle up, by for example having Prime95 stress one of the two cores, then the simulation only requires 12 seconds to get to 100ms.
So here are my two questions:
1. Is Multisim 11 capable of using more than one CPU core while simulating? If yes, how can I get it to use more than one?
2. Probably not the right forum to ask, but is there a way to force Windows 7 Ultimate x64 to throttle up the CPU when Multisim starts simulating? Since Multisim does not seem to stress the only core it uses enough to throttle it up. Using Prime95 on one core does trigger a throttle up.
With regards,
Bart Grefte
Relevant specs:
Windows 7 Ultimate x64
Multisim v11
AMD A4-3400
16GB RAM

Completely forgot this topic....
Is there a good reason why there is no multicore support? Multisim can certainly use it for simulating.
As for the CPU throttling, I found a batch that can increase/decrease the "minimum processor state"-setting and it works immediately, no reboot required.
@echo off
powercfg.exe -getactivescheme > "%userprofile%\appdata\~apo.tmp"
set /p v_currentscheme= <"%userprofile%\appdata\~apo.tmp"
set v_currentscheme=%v_currentscheme:~24,36%
del "%userprofile%\appdata\~apo.tmp"
powercfg -setacvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -setdcvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -s %v_currentscheme%
exit
Usage is simple:
Start -> run -> c:\pathtobatch.bat 100
for "minimum processor state"-setting at 100%
Start -> run -> c:\pathtobatch.bat 5
for "minimum processor state"-setting at 5%
Please note that "set v_currentscheme=%v_currentscheme:~24,36%" is not the same for every language. The original batch had "set v_currentscheme=%v_currentscheme:~19,36%" (most likely for the English version of Windows 7), but since my Windows install is in Dutch, I had to change it in order for it to work.
Running the batch with @echo off removed will show why.

CPU Multi core processor only using 1 core

I have a 12 core CPU which works fine when rendering in Premier Pro utilizing all 12 cores but when I render in Media Encoder it only uses 1 core. This is a recent event that has occurred recently, has anybody got an idea what is happening?

hanugro,
I did some searching, and the processor you want, is not available in many places.
Even TigerDirect.com doesn't even list this processor. And, it must be VERY EXPENSIVE ! ( I'm guessing it will be $1,500 ? ), the one you list has a 1333 MHz bus speed !!
This is the most expensive processor they have listed:
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3241539
It is currently $579 ( as of today, Feb.14, 2008 )
