[mvapich-discuss] PMGR_COLLECTIVE ERROR: MPIRUN_RANK

[senthil.natesan at ndsu.edu]

Dear MVAPICH developers/users,

I compiled Amber PMEMD (molecular dynamics) program (www.ambermd.org)with
MVAPICH-1.1.0 successfully, but when I am submitting the job, it gives the
following error for every node.

PMGR_COLLECTIVE ERROR: unitialized MPI task: Missing required environment
variable: MPIRUN_RANK

My system is craycx1 with RHEL 5.3 (x86_64), with both ethernet and
infiniband hybrid cables/switches. (6 nodes, each node intel xeon Quad
processors).

Any suggestions would be appreciated.

Thanks,

Senthil Natesan
