Hi all！

I experiment the intel caffe in my machine which cpu has 12 core, but i found that the utilization rate of cpu is only 600%.

I want to Maximize the use of cpu. how to set the number of processes in intel caffe?

are you sure that? intelcaffe allocate thread number according to phyical core number if no OPNEMP env variable setting.

pls be aware of the difference between physical core and logical core. and pinning each thread to physical core is our recommendation for best perf.

Hi ftian，thanks for your reply. I indeed mistook the logical core to physical core. I check my machine, its physical core number is 6, so the utilization rate of cpu is 600% is normal.
