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

[Pavan Balaji]

The default publish mechanism is to use the file-system assuming there's 
a shared file system. Does that not work for you?

Alternatively, you can use --with-name-publisher=pmi. In this case there 
are two possibilities:

1. If your publish/lookup is happening within the same application 
(launched using one mpiexec), then there's nothing you need to do. Just 
launch the application normally, and it'll function correctly.

2. If your publish/lookup is happening between two different 
applications (launched using more than one mpiexec), then you'll need to 
launch a separate nameserver (./mpich2-install/bin/hydra_nameserver) and 
get each mpiexec to connect to this common nameserver by passing the 
-nameserver option to mpiexec. mpiexec -nameserver -help will give you 
more information.
