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 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 two servers at hand, both with 16 cores. The first is running Debian, the second running Ubuntu.
I have written a small multithreaded java app that creates 16 threads.
I have a 6 core processor and have noticed some performance issues. I recognize coming from Windows things won't be the same. But I've heard that it's not incredibly uncommon for linux to not utilize all cores available. Is there a command or series of commands to be sure linux recognizes my processor runs all 6 cores?
When it comes to multicore processors, if the frequency is rated as 3GHz, does that mean it is 3 GHz per core or 3 GHz divided by the number of cores.
Like in the title, for a 3 GHz dual core, would it be 3 GHz per core or 3 GHz / 2 cores = 1.5 GHz per core?
Thanks for your help.
I'v got a server with 2x1Gb nics, 8 cores CPU. The nics are bonded using bonding driver with mode 803.2ad. I faced the problem with changing network cards' affinity . The irq interrupts coming from nic cards are spread to 8 cores. I tried to limit the number of irq request against 2 cores of the CPU by editing /proc/irq/devicIRQXX/smp_affinity, but it did not work for me.
Hi.I started to experience an issue, where my linux stops getting one cpu core. Even /proc/cpuinfo and /sys/devices/system/cpu returns 5 cores. Mi server has 6 CPU cores.
I'm looking for a laptop. Any help would be much appreciated.
Obviously I want it to run Linux without problems.
I need 16g RAM or better, quad core i7 or better, 17" or better, and good multiple monitor support.
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....
