I want to use only 1 thread per physical core on both the CPUs, but I'm not able to do it.

Use the tool I've posted a few posts above (msg27696971) to identify physical cores, and then use the appropriate affinity mask.

Do not underestimate the correct affinity setting, some algos (like lyra2*) are spread between all cores if thread count < core count, e.g. u have 4 cores but wanna use 2 threads, than u may get all 4 cores 50% utilized, and that is not what you usually want :-)

...

Thank you for you suggestion.
Here is the output of enum tool from AMD

Number of active logical processors: 32
Number of active physical processors: 16

Number of threads per processor core: 16

I'm assuming that using an affinity mask like 0xAAAAAAAA or 0x55555555 it will use only odd or even logical processors of the 32 available. Am I wrong?
