[mvapich-discuss] Error initializing MVAPICH2 ptmalloc2 library

[Daniel WEI]

Dear all,

What might be the reason for this error? I googled and couldn't find a clue.

I am using xsede lonestar, and I can run the job with small number of cpus,
like 12 or 24, but when I tried to use 1200 these days, it always shows the
error below.

Please help. Thanks

TACC: Starting up job 862193
TACC: Setting up parallel environment for MVAPICH ssh-based mpirun.
TACC: Setup complete. Running job script.
