[mpich-discuss] Can an mpich2 run be started without mpiexec

[Pavan Balaji]

If you run an application without mpiexec, it's similar to running it 
using mpiexec but with just one process.

That is, the below statements are equivalent:

  $ ./foo

  $ mpiexec -n 1 ./foo

Our local IT types have been hounding me about this, and I know of no other way than to use mpiexec to start my app.  Is that possible to initiate it programmatically?
