Humus is a pair of computers located at Dalhousie University managed by ACENET on behalf of researchers who purchased the equipment.
Humus is integrated with the [[Nefelibata]] cluster, but Humus and the balance of Nefelibata are owned by two different research groups.
=== Access ===
You may only access Humus with the permission of the contributing Principal Investigator.
If you don't have access to Humus and believe you should, please write to support@ace-net.ca and say so.
Copy the PI, and mention in the email your Digital Research Alliance of Canada username.
When you have access, you can log in like so:
ssh -J username@nefelibata.ace-net.ca username@humus216
or
ssh -J username@nefelibata.ace-net.ca username@humus217
Supply your Alliance password when prompted.
We strongly recommend creating and installing an SSH key pair and using that for access after your first login.
* For more on key pairs, see https://docs.alliancecan.ca/wiki/SSH_Keys.
* For more on SSH in general, see https://docs.alliancecan.ca/wiki/SSH.
=== Software ===
Humus uses the same [https://docs.alliancecan.ca/wiki/Using_modules modules] system as Alliance clusters,
providing access to the same list of [https://docs.alliancecan.ca/wiki/Available_software available software].
=== Job scheduling ===
You can, if you wish, submit batch jobs using the Slurm job scheduler.
The Humus nodes carry NVidia A30 GPUs, so the following command will run `jobscript`
on one entire node:
sbatch --time=6:0:0 --gres=gpu:a30:1 --cpus-per-task=64 --mem=0 jobscript
