I am going to use MPI on condor.
Can any one tell me what is ch_p4?
the condor documentation says
"The MPI universe in Condor currently supports MPICH versions 1.2.2,
1.2.3, and 1.2.4 using the ch_p4 device"
MPICH supports several different communications "devices", such as
myrinet, infiniband and TCP. the "ch_p4" device is the TCP "device".
It is the usual device, unless you have special, high-speed
interconnects between your machines.
