 Hi,
 �With MPICH2 1.2.1p1 you should be able to use the Nemesis channel using the "-channel" option of mpiexec (mpiexec -n 2 -channel nemesis mympipgm.exe).

 Hi,
 Try the latest stable release of MPICH2 ( http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads ).
 It looks like you are explicitly using the sock channel (with "-channel sock" option of mpiexec) for running your MPI job. Is there any reason why you want to use the sock channel instead of the default nemesis channel (If you don't use the "-channel" option mpiexec should pick the nemesis channel) ? Sock channel is old and we recommend all users to use the Nemesis channel instead.

 I tried to ping test on each PC and its failed. It seem like I got no response from the network adapter.
 I disabled the network adapter and enabled it then everything seem to be normal again.
 Both PC are connected by using a crossover cable.
 Thanks.

 Koh
