[MPICH] Dynamic Processes woes :S

[Kevin C.]

I have read the install and user guide to MPICH2 and could not find any 
information on how to use the "dynamically create/destroy individual MPI 
processes on specific host machines" - as specified in the new features of 
MPICH2.

Please can someone tell me how to dynamically create/destroy MPI processes 
on specific host machines from one host.

Also, does the MPICH-G (grid version) contain the above functionality as 
well? Please tell me more details.

Many thanks
Kev
