Announcements

Grace Maintenance

The biannual scheduled maintenance for the Grace cluster will be occurring February 1-3. During this time, the cluster will be unavailable. See the Grace maintenance email announcement for more details.

Data Transfers

For non-Milgram users doing data transfers, transfers should not be performed on the login nodes. We have a few alternative ways to get better networking and reduce the impact on the clusters’ login nodes:

  1. Dedicated transfer node. Each cluster has a dedicated transfer node, transfer-<cluster>.hpc.yale.edu. You can ssh directly to this node and run commands.
  2. “transfer” Slurm partition. This is a small partition managed by the scheduler for doing data transfer. You can submit jobs to it using srun/sbatch -p transfer … *For recurring or periodic data transfers (such as using cron), please use Slurm’s scrontab to schedule jobs that run on the transfer partition instead.
  3. Globus. For robust transfers of larger amount of data, see our Globus documentation.

More info about data transfers can be found in our Data Transfer documentation.

  • MATLAB/2021b is now on all clusters.
  • Julia/1.7.1-linux-x86_64 is now on all clusters.
  • Mathematica/13.0.0 is now on Grace.
  • QuantumESPRESSO/6.8-intel-2020b and QuantumESPRESSO/7.0-intel-2020b are now on Grace.
  • Mathematica documentation has been updated with regards to configuring parallel jobs.
