If an application opens a file for reading from multiple processes using MPI_COMM_SELF (or another communicator that has distinct process groups but the same comm-id, as can happen as the result of comm_split), the naming chosen for the lockedfile or the mmapped file used by the sharedfp/sm component would collide. This patch ensures that the filename is different by integrating the process id of rank 0 for each sub-communicator. This fixes one aspect of the problem reported in github issue 5593 Signed-off-by: Edgar Gabriel <egabriel@central.uh.edu> |
