[Darshan-users] Code hanging in Darshan processing MPI finalize

[Hedges, Richard M.]

I am having a code hang, apparently in the processing of Darshan data,
after MPI_Finalize is called on a BG/Q.  The code works fine on its own at
scale, and with Darshan for a 4 process test case.  For anything 128 procs
and up, it seems to hang in the Drashan processing.

Anyone seeing something like this?

Thanks,
- Richard
