Only MPIch, p4 is supported, not other MPI implementations. Last time I
on Linux, 1.2.5 didn't work - you have to use 1.2.2, 1.2.3 or 1.2.4 (this

The example in the manual shows how a single controller can control both
types of job
while giving priority to the MPI ones. I am fairly certain that you could
add the time
restraint code in there - good idea, I like it!
