[mpich-discuss] installing and using MPI_PUBLISH_NAME and MPI_LOOKUP_NAME with mpich2

[Bernard Secher - SFME/LGLS]

Hi Pavan,

I can run my application on system with a shared file-system, but also 
on system without shared file-system.

The usage is to perform coupling between parallel programs with more 
than 1 process.

My test program uses the same executable, but it can be different 
executables.
