HPC pack 2012 update3 linux node CPU utilization


  • Hello everyne,

    I am using HPC 2012 update 3, also successfully added Linux computing node, can be used normally.

    However, a problem has been discovered, that is, the utilization of computing nodes of Linux can not reach 100% of CPU.

    For example, the machine has 20 cores, and I created a task with 20 tasks. When the machine runs, the 20 tasks will run at the same time, but the 16 CPU utilization of the task is 100%, while the CPU utilization rate of the 4 tasks is only 50%. Do you observe the same phenomenon when you use it?

    How fix it? Please help me

  • What if you run the 20 tasks manually on the linux node directly, will the CPU utilization reach 100 CPU? If you can reach CPU 100% then we think it is caused by CGroup, and you could disable CGroup by comment out two lines within "" on the linux node:


    command -v cgexec > /dev/null 2>&1 && CGInstalled=true
