Hi,
My dual Xeon desktop with SMT (1 core, 2 threads) is reported by the
kernel in a very strange way. The kernel thinks the first physical
processor as socket 0 but the second physical processor as socket
3. There is no socket 1 or 2 either reported by /proc/cpuinfo or
/sys. This breaks the for loop code counting max sockets in
load_cache() as it assumes the sockets # are consecutive (and
allocating memory for non-existence sockets). As a consequence,
the total number of socket is incorrect neither.
I don't know if we are going to see nonconsecutive processor
id, core id or thread id reported by kernel in reality.
I attached the /proc/cpuinfo and /sys for your reference.
BTW, Jeff, where is the tracker for plpa? the same as OpenMPI?
