[mpich-discuss] MPICH2, ONE OF THE PROCESSES TERMINATED BADLY: CLEANING UP

[Wei Huang]

Hi, there,


I am trying install mpich2-1.4rc2 on a Linux cluster with pgi.
When I use an old version (6.2.5) of PGI to build, the mpi example worked fine.
(But have problem to build other software.)

But with a new version (8.0.4), after the build, when I run the example
program, I got seg. fault with w processors.

Anyone knows what is wrong here?

Thanks,

Wei
