Waltz temporary access

Peloton's Waltz server has been mounted on some Hive compute nodes. Waltz is currently only connected to Hive over InfiniBand, so you need a node with InfiniBand to be able to access it. You can request a node with InfiniBand by adding the --constraint=mpi flag to your sbatch/srun job. See the MPI documentation for more information.

The path to access Waltz is /nfs/peloton/waltz/. If you have permission issues, please open a ticket with HPC@UCD support.

InfiniBand Limitations

Only some of the Hive nodes have InfiniBand, so use the --constraint=mpi flag to ensure your job can access Waltz.

Neither of the Hive login nodes (login1.hive, and login2.hive), nor transfer.hive have InfiniBand, so you cannot access Waltz from Hive's login or transfer nodes.
