When the environment variable TMPDIR is set to the current directory, not matter it is '.', './', or full path, the Intel MPI failed to run.


This happens on all MPI versions ( including 4.0)

[linfa@babbage testrun]$ setenv TMPDIR .
[linfa@babbage testrun]$ {/opt/intel/impi/3.2.0.011/bin64/mpirun} -n 2
mpdboot_babbage.tx.altair.com (handle_mpd_output 730): Failed to establish a socket connection with babbage:54848 : (111, 'Connection refused')
mpdboot_babbage.tx.altair.com (handle_mpd_output 747): failed to connect to mpd on babbage

If you want an expert explanation of this problem, the cluster and HPC forum would be a more likely place to ask.
