[OMPI users] mpirun tries to ssh to local machine

2013-08-26 Thread Federico Carotenuto
Hi all, I'm currently having this issue with mpirun: I want to launch a program only on the cores of the local machine, but every time I run an mpi program it says that the host 127.0.0.1 with it's associated key is unkown and asks me if I want to add it to the list of ssh known hosts.

Kind Reuti, Thanks for your quick reply! I'm afraid I didn't set a machinefile...that may be the problem: I'm fairly new to MPI and SSH and I'm still quite confused even after reading some tutorials. My etc/hosts contains: 127.0.0.1 localhost and 127.0.1.1 modelstation (modelstation is

Kind Reuti, I'm start thinking I've got some compilation issue with MPI: I'm afraid I've got the MPICH 1 coming with the PGI compiler installation, because if I try to run mpiexec the terminal answers with "The program 'mpiexec' can be found in the following packages: *lam-runtime *mpich2

Kind Reuti, as you suggested I proceeded to install Openmpi 1.6.5 and changed the environmental variable MPI_ROOT to the new folder, should I know source the commands in .bashrc to be sure to be able to execute the right mpirun and mpiexec (something like source /home/modelstation/Softwar

[OMPI users] Unable to schedule an MPI tasks

2013-08-26 Thread Ng Shi Wei
Hi all, Due to the time constraints, I would like to run the mpi program by scheduling the program to run on desired time using the "at" command. However, it seems that the mpirun doesn't execute the mpi program at the desired time using the "at" command. I would like to ask is there any other m

Perhaps I don't understand, but mpirun has no problem being executed using the "at" command. Perhaps the problem is that you don't have permission for "at"? Per the man page: The superuser may use these commands in any case. For other users, permission to use at is determined by th
