Excellent, that’s exactly the sort of thing I was hoping someone on the list
would know how to determine. Looks like (see lstopo output at the end) 0,16
is one real core, 1,17 another, etc. That’s sort of what I expected. Looks
like my original message truncated the list, and of course now that process
isn’t running. Here’s a current list, with PSR as the second column
5173 2 ? 00:10:35 vasp.para.intel
5182 5 ? 00:10:35 vasp.para.intel
5184 9 ? 00:10:36 vasp.para.intel
5177 16 ? 00:10:35 vasp.para.intel
5169 17 ? 00:10:35 vasp.para.intel
5187 19 ? 00:10:35 vasp.para.intel
5175 20 ? 00:10:36 vasp.para.intel
5179 22 ? 00:10:35 vasp.para.intel
5171 23 ? 00:10:35 vasp.para.intel
5178 24 ? 00:10:36 vasp.para.intel
5170 26 ? 00:10:36 vasp.para.intel
5181 27 ? 00:10:36 vasp.para.intel
5174 28 ? 00:10:36 vasp.para.intel
5172 29 ? 00:10:36 vasp.para.intel
5176 30 ? 00:10:36 vasp.para.intel
5189 31 ? 00:10:36 vasp.para.intel
That corresponds to physical core numbers
2,5,9,0,1,3,4,6,7,8,10,11,12,13,14,15
So I guess it really is associating each process with a single unique core. I
guess that’s good for openmpi, although it does undercut my core binding
hypothesis.
thanks,
Noam
