I'm not quite sure, not for the bulk of the work, but maybe in its parallel libraries (e.g. scalapack).
From the trace, at least 'if (comm_ptr1->comm_kind == MPID_INTRACOMM) ' seems true.
It does use cartesian communicators in these compares, but this didn't trigger it in the testcase. Joost On 04/28/2014 02:34 PM, VandeVondele Joost wrote:
Unfortunately, the leak doesn't reproduce with some testcases I tried to construct. I'm not sure what makes the real application different from the testcases, so I don't have much more info than the backtraces.
is cp2k using intercommunicators? ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
