How-To: Connect to High-Memory Nodes¶
HPC 4 Research Only
High memory nodes are available on the HPC 4 Research cluster only. However, the HPC 4 Clinic cluster nodes have 350GB+ of RAM which is likely enough for many applications.
You have to register with email@example.com for requesting access.
Afterwards, you can connect to the High-Memory using the
highmem SLURM partition (see below).
Jobs allocating more than 200GB of RAM will be routed automatically to the
In the cluster there are four High-memory used which can be used:
res-login-1:~$ sinfo -p highmem PARTITION AVAIL TIMELIMIT NODES STATE NODELIST highmem up 14-00:00:0 3 idle med040[1-4]
To connect to one of them, simply allocate more than 200GB of RAM in your job.
res-login-1:~$ srun --pty --memory=300GB bash -i med0401:~$
You can also pick one of the hostnames:
res-login-1:~$ srun --pty --memory=300GB --nodelist=med0403 bash -i med0403:~$
After successfull login, you can see that you are in "highmem" queue:
med0403:~$ squeue JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON) [...] 270 highmem bash holtgrem R 1:25 1 med0403
