hydra_nameserver(1) HYDRA hydra_nameserver(1) 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 LOCATION /var/tmp/vc8XKeIJUJ/mpich-5.0.1/src/pm/hydra/mansrc/hydra_nameserver.txt 4/10/2026 hydra_nameserver(1)
