[mpich-discuss] mpich2-1.2.1p1 runs for a while and failed

[Koh Voon Li]

Hi,
Is there anyway to know that I am running with nemesis channel instead of
sock channel?
I am launching my job via config file which is something look like this as
below.

channel
nemesis
exe \\FDS2-PC\Project\Paradigm\V20\fds5_mpi_win_64.exe Paradigmv4-20.fds
dir \\FDS2-PC\Project\Paradigm\V20\
hosts
FDS2-PC 6
WIN7-PC 6

Thanks.

Regards,
Koh
