[mvapich-discuss] Trouble building MVAPICH2-1.0.3 with any compiler other than gcc

[Dhabaleswar Panda]

Hi David,

You might have noticed that we made a release of MVAPICH2 1.2RC1 yesterday
night. This has multiple start-up schemes including the traditional
MPD-based and also a new scalable mpirun_rsh-based (similar to MVAPICH).
We have verified that the MPD-based startup works with TotalView for all
compilers. The complete TotalView support with the new mpirun_rsh-based
scheme is not there yet. We are working on it and plan to have it in the
final release version.

You can check the MPD-based startup + TotalView for all compilers for this
release and let us know if it works from your view point.

Thanks,

DK
