Recently, I was upgrading openmpi from 1.4.2 to 1.4.3, now, I can see
that system cpu usage is too high, for example, namd application has 40%
system cpu and HPL benchmark has 80%! of system cpu usage, in the
previous version, the system cpu usage was never more than 5%.
I was reading user list archives and I found threads that speak about
this, my question is, version 1.4.3 has issues ? Downloadable version
is not patched?
