My guess (looking at the BG/P CNK kernel code) is that /sys is not
present on a BG/Q compute node, only on its I/O nodes (which run a
Linux kernel), and so the code is only picking them up when the I/O is
being redirected via an I/O node (i.e. when MPI is in play).
Now I'd have thought that would happen with or without MPI, but who
knows..
cheers,
Chris
