Re: [OMPI devel] RFC: fix leak of bml endpoints

Ok figured it out. There were three problems with the del_procs code: 1) ompi_mpi_finalize used ompi_proc_all to get the list of procs but never released the reference to them (ompi_proc_all called OBJ_RETAIN on all the procs returned). When calling del_procs at finalize it should

Re: [OMPI devel] RFC: fix leak of bml endpoints

The solution you propose here is definitively not OK. It is 1) ugly and 2) break the separation barrier that we hold dear. Regarding your other suggestion I don’t see any reasons not to call the delete_proc on MPI_COMM_WORLD as the last action we do before tearing down everything else.

[OMPI devel] RFC: fix leak of bml endpoints

What: We never call del_procs in the procs in comm world. This leads us to leak the bml endpoints created by r2. The proposed solution is not idea but it avoids adding a call to del procs for comm world. Something I know would require more discussion since there is likely a reason for that. I

Re: [OMPI devel] about btl/scif thread cancellation (#4616 / r31738)

Nathan, this had no effect on my environment :-( i am not sure you can reuse mca_btl_scif_module.scif_fd with connect() i had to use a new scif fd for that. then i ran into an other glitch : if the listen thread does not scif_accept() the connection, the scif_connect() will take 30 seconds

[OMPI devel] r31765 causes crash in mpirun

Folks, since r31765 (opal/event: release the opal event context when closing the event base) mpirun crashes at the end of the job. for example : $ mpirun --mca btl tcp,self -n 4 `pwd`/src/MPI_Allreduce_user_c MPITEST info (0): Starting MPI_Allreduce_user() test MPITEST_results:
