Ares is built with Infiniband EDR interconnect and nodes of the following specification:

Partition	Number of nodes	CPU	RAM	Accelerator
plgrid and plgrid-*	532	48 cores, Intel(R) Xeon(R) Platinum 8268 CPU @ 2.90GHz	192GB
plgrid-bigmem	256	48 cores, Intel(R) Xeon(R) Platinum 8268 CPU @ 2.90GHz	384GB
plgrid-gpu-v100	9	32 cores, Intel(R) Xeon(R) Gold 6242 CPU @ 2.80GHz	384GB	Tesla V100-SXM2

Job submission

Jobs Ares is using Slurm resource manager, jobs should be submitted to the following partitions:

Name	Timelimit	Remarks
plgrid	72h	Standard partition.
plgrid-long	168h	Used for jobs with extended runtime.
plgrid-testing	1h	High priority, testing jobs, limited to 3 jobs.
plgrid-bigmem	72h	Jobs using an extended amount of memory.
plgrid-now	12h	The highest priority, interactive jobs, limited to 1 running job.
plgrid-gpu-v100	72h	GPU partition.

Storage

Available storage spaces are described in the following table:

Location	Physical location	Purpose
$HOME	/net/people/<login>	Storing own applications, configuration files
$SCRATCH	/net/pr2/scratch/people/<login>	High-speed storage used for short-lived data heavily used in computations.
group storage	/net/pr2/projects/plgrid/<group name>	Long term storage, used for data living for the period of computing grant.

Current usage, capacity and other storage attributes can be checked by issuing the hpc-fs command.

...

and the environment can be purged by:

module purge

Ares is following Prometheus' configuration and usage patterns. Prometheus documentation can be found here: https://kdm.cyfronet.pl/portal/Prometheus:Basics
