I wonder whether anyone could speak about exactly what
versions of the supporting operating systems we should expect to
work, particularly specifics about compilation requirements and
instructions.
I've been trying to build hwloc-1.2 on some of our old
AIX systems (5.2, 5.3, 6.1), w
Interesting. Thanks for the tip about the SSE instruction.
In fact one machine has flags of:
--
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt
rdtscp lm 3dnowext 3dnow constant_tsc no

This is SSE4 indeed. You could check in grep sse4 /proc/c
Below is some disassembly generated from gdb from the core file that
was generated. The signal is an illegal instruction, not a segv as I
mentioned previously (sorry about that). I also included some
information about the lstopo file and configure parameters below.
Thanks,
Josh

The odd thing about this environment is that the head node seems to
have a slightly different setup than the compute nodes (not sure why
exactly, but that's what it is). So hwloc is configured and runs
correctly on the head node, but when it is asked to run on the compute
nodes it segvs at the call
