Argo
Argo is a computer cluster located at Memorial University of Newfoundland,
installed in late 2023, and
managed by ACENET on behalf of researchers who have purchased the equipment.
The environment is very similar the environment on to the
Alliance general-purpose systems,
with the exceptions described below.
Access
You may only access Argo with the permission of one of the contributing Principal Investigators. If you don't have access to Argo and believe you should, please write to support@ace-net.ca and say so. Copy the PI with whom you are associated, and mention in the email your Digital Research Alliance of Canada username.
When your Alliance username has been added to the access control list for Argo, you can log in like so:
ssh username@argo.ace-net.ca
Argo uses the Alliance's multi-factor authentication and SSH-key authentication mechanisms. We strongly recommend that you register an SSH key and use that in place of password authentication.
Data transfer
Data transfers can use the login node; there is not currently a dedicated data-transfer node.
Software
Argo uses the same modules system as Alliance clusters, providing access to the same list of available software.
Job scheduling
The basic guidance on job scheduling is to ask for the run time, memory, CPUs, and GPUs you need and let the scheduler assign your jobs to nodes or partitions automatically.
Maximum run time is 14 days, which was determined in consultation with the two largest contributing Principal Investigators. If this is insufficient, have your PI contact support@ace-net.ca to request a revision of this limit.
All compute nodes at Argo are contributed by one or another research group. Members of each research group (or any other group designated by the contributing PI) can run jobs on their contributed nodes with run-times of up to 14 days.
Idle compute nodes contributed by other research groups than your own may be used by jobs of up to 1 day (24 hours) run-time.
You should never have to use --partition;
your job should automatically be assigned a list of suitable partitions at submission time.
Likewise you should never have to use --account
since all users on Argo belong to one and only one Slurm account.
