Hey, I am new to clusters and hope that it is okay for me to pose a questions here. I have tried to submit a program which should be executed parallel but as I submit it - it only runs on one processor. First I used the chm-parallel environment which is default at this cluster. Than I tried to change the parallel environment to mpi and use mpirun but it gave me the error-message that it couldnt find the mpi environment. I have used the mpirun on the "helloworld.c"-program and when executed alone it returns from the specified notes. When I go to opt/sge - both the chm and mpi environment are there - how can I enforce it to use the mpi environment? - Given the full-path and to which file in the directory? (there is a startmpi.sh ?) Thanks in advance Best regards Per -------------- next part -------------- An HTML attachment was scrubbed...
