Jed Cluster

Research Cluster

This cluster is for pay-per-use accounts. Master students and courses cannot use Jed. For the educational CPU cluster check Helvetios.

Useful info#

Connecting to the clusters#

To connect to the cluster you should:

ssh <username>@jed.hpc.epfl.ch

Here's the list of current fingerprints you should expect when connecting to this cluster:

QOS#

The standard QOS are:

  • serial for jobs using up to 1 node (72 cores), with a time limit of 7 days. This is the default;
  • parallel for jobs using more than 1 node, with a time limit of 15 days;
  • bigmem for running jobs on the 1 TB nodes (15-day time limit);
  • hugemem for the 2 TB nodes (3-day time limit).

Choose one with -q <qos> or --qos <qos>.

Partitions#

There are three partitions on Jed, to differentiate nodes based on their RAM:

  • standard, the default, for the nodes with 512 GB of RAM (7000 MB/core allocated by Slurm);
  • bigmem, for the 42 nodes with 1 TB of RAM (14'000 MB/core allocated by Slurm);
  • hugemem, for the 2 nodes with 2 TB of RAM (28'000 MB/core allocated by Slurm).

Choose one with -p <partition> or --partition <partition>.
