Hi Takahiro, Thanks very much for the patch and the test!
After the git migration we'll open an issue and patch nbc_iallgather. This will get pushed to 1.8.4. Howard -----Original Message----- From: devel [mailto:devel-boun...@open-mpi.org] On Behalf Of Kawashima, Takahiro Sent: Monday, September 29, 2014 10:22 PM To: de...@open-mpi.org Subject: [OMPI devel] [patch] libnbc intercommunicator iallgather bug Hi, The attached program intercommunicator-iallgather.c outputs message "MPI Error in MPI_Testall() (18)" forever and doesn't finish. This is because libnbc has typos of send/recv. See attached intercommunicator-iallgather.patch for the fix. The patch modifies iallgather_inter and iallgather_intra. The modification of iallgather_intra is just for symmetry with iallgather_inter. Users guarantee the consistency of send/recv. Both trunk and v1.8 branch have this issue. Regards, Takahiro Kawashima, MPI development team, Fujitsu
