Well I don't get why you would get a Multi-core processor if it doesn't. If I was using Just Ubuntu would multiple cores really matter as any CPU intensive things (Gaming as an example) that would use multiple cores are non-existent on Ubuntu.
I'm also talking about the Physical Limitations of Linux as a whole. Are there any Programs that use multiple cores?
I have three machines, and I've been experimenting with commands to set the CPU frequency scaler by hand. This command works on each of my machines, except one of them:
Code:
sudo cpufreq-set -r -g performance
On both of my Core i series machines, that sets the CPU governor to performance for each core.
Semiconductor IP vendor Virage Logic, which is soon to be acquired by Synopsis, released Linux toolchains for its 32-bit RISC/DSP ARC processor cores. The ARC GNU 2.3 Toolchain suite is available for the company's ARC cores, and the ARC Linux 1.3 distribution is available for its high-end, ARC 750D RISC/DSP processor core, which targets consumer electronics devices....
Hi,
Could you please Tell me the command to find the number of cores in red hat box?
I have tried cat cat /proc/cpuinfo | grep processor | wc -l command to find the number of processers.
But need to fond the number of cores.
Is there any difference between core and processor?
Please help on this.
Regards,
Vikas.
AMD currently announce that the already shipped 8 and 12 cores processor Magny-Cours for OEM and selected manufacturers. Magny-Cours is a server CPU next generation from AMD. This new processor contains 2 cores of Istanbul. Because AMD does not have the original octal-core, the Magny-Cours 8 cores is built based on 2 Istanbul processors.
I have a Xeon E3-1230 processor, which has 4 physical cores, but has hyperthreading so an operating system running on it sees 8 logical cores.
I installed VMware ESXi and am creating virtual machines to run on it.
I have a Dell server with two cpus, each cpu has 6 cores, and each core is hyperthreaded (i.e. should be equivalent to two virtual cores).
I have a server with an Intel Core i7 processor (4 cores). If I view processor activity in Task Manager I see that there are 8 cores.
I've tried to decide processor affinity rule for my applications according to /proc/cpuinfo , My redhat Linux showes
processor : 0 to 47 , means server has 48 processor unit
physical id : 0 to 3 , means server has 4 cpu sockets
cpu cores : 6 , means each socket has 6 cores
siblings : 12 , means each core has 2 hyperthreads
So totally , this server has 4 * 6 * 2 = 4
