I compiled LAM/MPI with xlf90, and I am running one of my benchmarks.
When I specify 1 thread, and I check top, the thread is taking up no
processor time, so it never does anything. When I specify two threads,
1 thread does nothing, and the other one works at 100%. Any idea on
what might be causing this? When configuring LAM, I had to specify
--with-fc=/opt/ibmcmp/xlf/8.1/xlf90 --with-memory-manager=none. I had
to do the memory manager one because I was getting that problem with -u
_lam_darwin_malloc_linker_hack.
Thanks,
Jon
