[mpich-discuss] what is the difference between message passing interface and multi threading?

[Mahesh Doijade]

Hi Jack,
             If you are considering only a single node with multiple
processor then multi-threading is the best way, also the performance is
better. And for clusters i.e running a program to span across multiple
nodes then MPI is the probably the best way. Also you can embed
multi-threading within each MPI processes on these nodes which are running
given MPI program.
