Also, is open MPI 1.1 compatible with MPI 1.2.3, I mean to ask is whether a MPI executable generated using 1.1 is executable by 1.2.3? i am trying to run a 1.1 generated executable on a remote 1.2.3 host when i get the following: amit@ubuntu-desktop-1:~/mpi-exec$ mpirun -np 3 --hostfile /home/amit/junk/mpi-codes/mpi-host-file --mca btl ^openib ./HellMPI amit@debian-desktop-1's password: amit@ubuntu-desktop-2's password: [ubuntu-desktop-1:13202] [0,0,0] ORTE_ERROR_LOG: Data unpack failed in file dss/dss_peek.c at line 59 [ubuntu-desktop-1:13202] [0,0,0] ORTE_ERROR_LOG: Data unpack failed in file dss/dss_peek.c at line 59 [ubuntu-desktop-1:13202] [0,0,0] ORTE_ERROR_LOG: Data unpack failed in file dss/dss_peek.c at line 59 Note that the host "debian-desktop-1" is 1.2.3 and the other 2 is 1.1 Regards -- Amit Kumar Saha [URL]:http://amitsaha.in.googlepages.com
