Using the core caffe cpu core?

Is there a way to limit the use of a Caffe CPU? For my instance, I have a Xeon E5-2699, and I would like to limit Caffe to use 9 cores, so 50 percent of the CPU. Most of the training is done on the GPU, and I have another development that I would like to work on at the same time. Is there an easy way to do this? Launch CentOS

I'm not sure how caffe is called, but you can use cgroups to limit CPU usage for processes on centos6 and beyond. An example of CPU usage restriction for 5 logical processors:

sudo mkdir -p /sys/fs/cgroup/cpu/fivecpus
sudo bash -c "echo 500000 > /sys/fs/cgroup/cpu/fivecpus/cpu.cfs_quota_us"
sudo bash -c "echo $$ > /sys/fs/cgroup/cpu/fivecpus/tasks"
your_command

, 500000 5 /sys/fs/cgroup/cpu/fivecpus/cpu.cfs_period_us

0

, - , taskset.

taskset CentOS:

sudo yum install util-linux

/ script 0 8 (9 ):

taskset -c 0,1,2,3,4,5,6,7,8 <your_command>
