[mvapich-discuss] PMI_KVS_Get error

[Mike Heinz]

Hi; I'm trying to diagnose a problem on a small cluster, and I'm hoping someone can point me in the right direction.

We have a standardized set of test scripts used to verify cluster operation, and on one particular cluster mvapich2 is failing with the following message:

mpirun_rsh: PMI key 'MVAPICH2_0001' not found.[cli_0]: readline failed

Googling around produced nothing useful - can someone suggest where I should look for this problem? Other MPIs are working correctly.
