Hi Ralf, sorry for the delay in the answer but I encountered some difficulties to access to internet since yesterday.
I have tried all your suggestions but I continue to experience problems. Actually, I have a problem with bjs on the one hand that I may submit to a bproc forum and I still spawn problem on the other hand. Let's focus first on the spawn problem. Even with a "bjssub -i bash" or "bjssub -n 1 -i bash" command, I continue to have the log: mpirun -np 1 main_exe machine10 main_exe: Begining of main_exe main_exe: Call MPI_Init main_exe: MPI_Info_set soft result=0 main_exe: MPI_Info_set node result=0 main_exe: Call MPI_Comm_spawn_multiple() -------------------------------------------------------------------------- Some of the requested hosts are not included in the current allocation for the application: ./spawned_exe The requested hosts were: machine10 Verify that you have mapped the allocated resources properly using the --host specification. -------------------------------------------------------------------------- [setics10:07250] [0,0,0] ORTE_ERROR_LOG: Out of resource in file base/rmaps_base_node.c at line 210 [setics10:07250] [0,0,0] ORTE_ERROR_LOG: Out of resource in file rmaps_rr.c at line 331 This problem is observed whatever the slave node is on the same machine than the master or not. On the bjs side of the problem. I have run bjssub under gdb and I could observed that I did not go into the code part that setenv NODES variable, so I stayed with the default value NODES=0. The question is, is the spawn problem a result of the bjs problem ? or are they two independant problems ? The good thing would be to find some other people with a debian platform, bproc, bjs and openmpi active. So that, we could check if I have made something wrong during the installation phase or if there is really a incompatibility problem in open mpi. Thank you so much for all you support, I wish it is not succesful yet. Regards.

Probably what he wants is "bjssub -i /bin/bash" and start >> bpsh/mpirun from the new shell. I would recommend doing as they suggest. Also, they noted that you failed to specify the number of nodes you wanted on the bjssub command line. As a result, the system gave you only one node (hence the NODES=0 instead of NODES=0, 1). If you do a "man bjssub", or a "bjssub --help", you should (hopefully) find out how to specify the desired number of nodes. Hope that helps.

Good afternoon. I've just configured and installed the openmpi-1.1.2 on a kubuntu GNU/linux, and I'm trying now to compile the hello.c example without results. > root@kubuntu:/home/livestrong/mpi/test# uname -a > Linux kubuntu 2.6.15-23-386 #1 PREEMPT Tue May 23 13:49:40 UTC 2006 > i686 GNU/Linux Hello.c ------- #include "/usr/lib/mpich-mpd/include/mpi.h" #include <stdio.h> int main (int argc, char** argv) { MPI_Init(&argc, &argv); printf("Hello word.\n"); MPI_Finalize(); return(0); } The error that I'm finding is this: root@kubuntu:/home/livestrong/mpi/prueba# mpirun -np 2 hello 0 - MPI_INIT : MPIRUN chose the wrong device ch_p4; program needs device ch_p4mpd /usr/lib/mpich/bin/mpirun.ch_p4: line 243: 16625 Segmentation fault "/home/livestrong/mpi/prueba/hello" -p4pg "/home/livestrong/mpi/prueba/PI16545" -p4wd "/home/livestrong/mpi/prueba" Does anybody know what it can be the problem?
