[OMPI users] Error initializing openMPI

Hi, When running openMPI my system freezes when initializing MPI (function MPI_init). This happens only when I try to run the process in multiples nodes in my cluster. Running multiple instances of the testing code locally (i.e ./mpirun -np 2 greetings) is succesful. - rsh runs well, and is

Re: [OMPI users] Process 0 with different time executing the same code

There is nothing MPI specific in your code snippet. You should try to find out what is different in your code for node 0. You have mentioned that you have moved the root node to other nodes, so it's not machine specific. You might be setting up the arrays differently on the different nodes. You

Re: [OMPI users] Process 0 with different time executing the same code

Hi All, Thanks for the help. I think that I don't have the cache issue because all the processes have the same amount of data, and accessed in the same fashion. My problem is solved partially as I was using 2, 4, 8 , 16, 32 and 64 processes for my application code. Now what I did I used 3
