[CIG-SHORT] ch_p4

[Leif Strand]

Tabrez,

PyLith should work fine on a cluster -- provided that it is built from 
source, and is thus configured to use the MPICH installation on your 
cluster.

The prebuilt binaries, however, only work on a workstation/laptop. The 
PyLith binary package includes its own copy of MPICH, which is 
configured to use ch_shmem. If these binaries run at all on a cluster, 
most likely they will do the wrong thing: i.e., run exclusively on the 
login node, as opposed to running in parallel on the compute nodes.
