November 15, 201411 yr Hi everyone. I used the "lscpu" and "cat /proc/cpuinfo" and I got the following: lscpu cat /proc/cpuinfo Architecture: i686 CPU op-mode(s): 32-bit, 64-bit CPU(s): 1 Thread(s) per core: 1 Core(s) per socket: 1 CPU socket(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 44 Stepping: 2 CPU MHz: 2405.486 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 12288K processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 44 model name : Intel® Xeon® CPU E5620 @ 2.40GHz stepping : 2 microcode : 0x13 cpu MHz : 2405.486 cache size : 12288 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 11 wp : yes bogomips : 4810.97 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: My CPU is an Intel Xeon E5620, shouldn't report 4 cores? Is there something wrong? Thanks for your help. Max
November 15, 201411 yr Huh....it should report 4. I don't have a Xeon, so not sure. Hopefully someone else will chime in.
November 15, 201411 yr Author Thank you eroz. Hoe someone can shed a little of light on that. Cheers Max
November 15, 201411 yr Author Looking with more attention to the syslog I've seen the following: Nov 14 18:30:31 MaxMe kernel: Hierarchical RCU implementation. Nov 14 18:30:31 MaxMe kernel: ^IRCU restricting CPUs from NR_CPUS=8 to nr_cpu_ids=1. Anyone knows it already? Cheers Max
