Kuma#

Research Cluster

This cluster is for pay-per-use accounts. Master students and courses cannot use Kuma. For the educational GPU cluster check Izar.

Useful info#

Connecting to the clusters#

To connect to the cluster you should:

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

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

ECDSA

QOS#

The standard QOS are:

normal for jobs using up to 8 nodes, with a time limit of 3 days. This is the default;
long for jobs using up to 8 nodes, with a time limit of 7 days;
build for compiling your codes, with up to 16 cores on 1 node, 0 GPU and a time limit of 4 hours;
debug for debugging jobs on up to 2 nodes, with a high priority and a time limit of 1 hour.

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

Partitions#

There are 2 partitions on Kuma, to differentiate nodes based on GPU type:

h100, to use the Nvidia H100 GPU nodes (with FP64 capabilities);
l40s, to use the Nvidia L40s GPU nodes (with FP32 capabilities);

There is no default partition. You have to choose one.

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