How-To: Connect to High-Memory Nodes¶
Prequisites¶
You have to register with hpc-helpdesk@bih-charite.de 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 should be routed automatically to the highmem
nodes.
How-To¶
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
