mpiexec: Warning: main: task 0 died with signal 11 (raw 0x10b).

[Rayson Ho]

I am not a PBS user (I use GridEngine), but sounds like this line limits
the size of the process:

#PBS -l pmem=2mb

          pmem*     Maximum amount of virtual memory used by any
                    single process in the job.  Units: size.

And I correct??
