[mpich-discuss] Installing MPICH2-1.0.5p3 in a SMP cluster

[Suman Vajjala]

Hi,

 I have a strange problem. In one case, I installed mpich2 using gcc and
gfortran compilers and I get a CPU usage of 100% when I run parallel codes.
In the second case, I installed mpich2 with Intel icc and ifort compilers
(64bit, ver-11.1) and I get a cpu usage of 85%. Could it be because of the
configuration options used for the mpich2 installation? Do the codes always
have to show a 100% cpu usage?

Thanks and regards
Suman Vajjala
