|
hydra_nameserver \- program to support MPI
|
|
.I s name publishing features with hydra
|
|
.SH 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:
|
|
.nf
|
|
shell@myhost1$ hydra_nameserver &
|
|
shell@myhost1$ mpiexec -hosts myhost1,myhost2 -n 4 -nameserver myhost1 ./a.out
|
|
.fi
