How to request an interactive GPU on ARC
GPUs on ARC
Please remember, that interactive jobs on ARC should be limited to '5 hours or less. Do not request more than 5 hours for your interactive jobs on ARC.
Currently, there are three partitions on ARC that have usable CUDA GPUs, gpu-v100, gpu-a100, and bigmem.
The arc.hardware tool can be used to see that.
$ arc.hardware
Node specifications per partition:
================================================================================
Partition | Node CPUs Memory GPUs Node list
| count /node (MB) /node
--------------------------------------------------------------------------------
bigmem | 2 80 3000000 fm[1-2]
| 1 40 4127000 a100:4 mmg1
| 1 40 8256000 a100:2 mmg2
.........
gpu-v100 | 13 40 753000 v100:2 fg[1-13]
.........
For more information about finding hardware on ARC, see How to find available partitions on ARC.
Example 1
1 GPU and 4 CPUs on the gpu-v100 partition for 1 hour (16 GB of RAM):
salloc -N1 -n1 -c4 --mem=16GB --gres=gpu:1 -p gpu-v100 -t 1:00:00
Example 2
1 GPU and 4 CPUs on the bigmem partition for 1 hour (256 GB of RAM):
$ salloc -N1 -n1 -c4 --mem=256gb --gres=gpu:1 -p bigmem -t 1:00:00
Checking the allocated GPU(s)
Use the nvidia-smi command to check the GPU:
$ nvidia-smi
