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

       .   vb  shell@myhost1$  hydra_nameserver & shell@myhost1$ mpiexec -hosts myhost1,myhost2 -n 4 -nameserver
       myhost1 ./a.out .  ve
