Comment:

 If both runs used hwloc, then it should not matter whether other software
 chose some other settings beforehand. If you look into the outputs after
 the lines "Setting thread CPU bindings" there, then you'll see that both
 runs used the same bindings.

 Actually, I just realize that some low-level systems may initialize
 themselves before thorn hwloc is called. In this case, it is likely that
 MPI would allocate some communication data structures, and those will
 likely all live on numa node 0 without these new options. This is bad.

 Please apply this patch.

 Please leave this bug report open (or open another one) until we checked
 all other mainstream systems.
