[mvapich-discuss] One of the program always stop on the way using MVAPICH2

[Yutaka Kubota]

Dear MVAPICH2 Discuss Member,

This is Yutaka Kubota from Cray Japan.

We have found a other problem on the MVAPICH2. Could you investigate
about problem?

One of the user's program always stop on the way that using MVAPICH2 and
ScaLAPACK. But if this program using MVAPICH don't stop on the way and
do until last. So I guess this problem is only MVAPICH2 not ScaLAPACK
and user program. And I tried to compile several MVAPICH2 version with
user program.(1.2p1, 1.4rc1, 1.4rc2 and trunk 9/15/2009 version) there
program stop on the way on individual different points and output core
files or not.

I had already had agreement to send you his program from user. I will
let only charger know download URL when I received email from charger.
