Ares is still under development, and , even despite our best efforts, Ares might experience unscheduled outages or even data loss. |
...
Note that Ares uses PLGrid accounts and grants, make . Make sure to request the access service called "Ares access" access service in the PLGrid portal.
Ares is built with Infiniband EDR interconnect and nodes of the following specification:
...
| Name | Timelimit | Remarks |
|---|---|---|
| plgrid | 72h | Standard partition. |
| plgrid-long | 168h | Currently unavailable. Used for jobs with extended runtime. |
| plgrid-testing | 1h | Currently unavailable. High priority, testing jobs, limited to 3 jobs. |
| plgrid-bigmem | 72h | Currently unavailable. Jobs For jobs using an extended amount of memory. |
| plgrid-now | 12h | Currently unavailable. The highest priority, interactive jobs, limited to 1 running job at most. |
| plgrid-gpu-v100 | 48h | GPU partition. |
...
Ares uses a new scheme of naming accounts for CPU and GPU computing grants. CPU only grants are named: grantname-cpu, while GPU accounts use grantname-gpu appropriate suffix suffix. Please mind that sbatch -A grantname won't work on its own, you . You need to add the the -cpu or -gpu suffix! Available computing grants, with respective account names (allocations), can be viewed by using the hpc-grants command.

| Location | Location in the filesystem | Purpose |
|---|---|---|
| $HOME | /net/people/plgrid/<login> | Storing own applications, and configuration files |
| $SCRATCH | /net/pr2/scratch/people/<login> or /net/ascratch/people/<login> | High-speed storage used for short-lived data used in computations. Data older than 30 days can be deleted without notice. Please note that scratch can have two physical locations. It is best to rely on the $SCRATCH environment variable. |
| $PLG_GROUPS_STORAGE/<group name> | /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.
