Hi,


I am trying to convert a simulation written using MPI to a real-time
visualization module under AVS.   I am using MPICH and AVS 5.2.  

We used to have a master and a slave program that we submitted using 
the mpirun command.  Now I had to intergrate the master program 
into the AVS module and I have to start this module by AVS.  Then 
I can issue a mpirun command for the slave program using a system 
call.  This does not seems to work. I guess due to the fact that 
master is already running and slave can not setup sockets to 
communicate to the master.

Is there a way to connect to a running programs using mpirun? Is 
there a better way?  I am not interested in writing a socket program 
(at least for now) to get the data from the standalone program.  I 
like to be able to start the slaves from the AVS module.

Any help is appreciated.

Thanks,

Upul
