Execute the following instructions to install the Open MPI system from within the directory at the top of the tree:
|
|
|
|
./autogen.sh (if this fails read the HACKING file)
|
|
./configure --prefix=/where/to/install
|
|
make install
|
|
|
|
To run an MPI program:
|
|
|
|
mpicc your-code.c
|
|
|
|
In order to run the program, you need to set some envs (use export for bash etc)
|
|
|
|
setenv MCA_common_ompi_cofs_job_handle pcm-cofs-job-handle
|
|
setenv MCA_common_ompi_cofs_comm_dir "/tmp/COFS"
|
|
setenv MCA_OOB_BASE_VPID 0
|
|
setenv MCA_REGISTRY_BASE_VPID 0
|
|
|
|
|
|
Then if you need to run say N nodes you need to set
|
|
setenv MCA_common_ompi_cofs_num_procs N
|
|
|
|
Then in the shell for each you would set
|
|
|
|
setenv MCA_common_ompi_cofs_my_vpid MYRANK
|
|
|
|
where MYRANK is 0 in one, 1 in the next etc
|
|
|
|
This rather cumbersome process will be replaced soon (we promise).

This is the world's greatest MPI, version 10.0a1r975.
