NAME

       hydra_nameserver -  program to support MPI s name publishing features with hydra

DESCRIPTION

       Hydra   is   the   default   name   service   for   MPI\   s   name   publishing  features
       (MPI_PUBLISH_NAME/MPI_LOOKUP_NAME). For programs launched by separate hydra  instances,  a
       separate  nameserver  mechanism  need be launched in order for the name publishing to work
       across multiple process managers.

       This can be achieved with hydra_nameserver. For example:
       shell@myhost1$ hydra_nameserver &
       shell@myhost1$ mpiexec -hosts myhost1,myhost2 -n 4 -nameserver myhost1 ./a.out
