how to run msieve or cado-nfs on mpi-cluster?
 

I've built a Mpich-cluster ( which has 3 nodes ) in ubuntu according to [url]https://help.ubuntu.com/community/MpichCluster[/url] , but i don't know how to distribute msieve on these nodes. Should I change the script by activating msieve with "mpiexec"? Or do anything else.

BTW, what are the paralell structures you are using to distribute msieve? Thanks for the suggestion!

Most of the folks here with multiple machines use the perl or python scripts, which have all the sievers write to a shared directory but do not expect MPI to be available. The NFS readme in the Msieve source repository goes into a lot of detail on using MPI to run the linear algebra.

The CADO tools have an MPI-aware perl script you can use, which is documented pretty thoroughly.
