Introduction

We have prepared a hal-login3 machine as a login node so that users can request computational resources from hal-dgx and overdrive.

How to login hal-login3

ssh <user_id>@hal-login3.ncsa.illinois.edu

Type sinfo to check the existing partitions

[dmu@hal-login3 ~]$ sinfo
PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
arm          up 15-00:00:0      1   idle overdrive
x86*         up 15-00:00:0      1   idle hal-dgx

Note: hal-login3 has no shared file system. Therefore, you can not find the same layout among these three machines.

Access to hal-dgx

You need to submit an interactive job and/or batch script to request some resources to run your jobs.

1. Interactive

Request 1x GPU along with 32x CPU cores for 4 hours

srun --partition=x86 --time=4:00:00 --nodes=1 --ntasks-per-node=32 --sockets-per-node=1 --cores-per-socket=16 --threads-per-core=2 --mem-per-cpu=4000 --wait=0 --export=ALL --gres=gpu:a100:1 --pty /bin/bash

Request 2x GPU along with 64x CPU cores for 12 hours

srun --partition=x86 --time=12:00:00 --nodes=1 --ntasks-per-node=64 --sockets-per-node=1 --cores-per-socket=32 --threads-per-core=2 --mem-per-cpu=4000 --wait=0 --export=ALL --gres=gpu:a100:2 --pty /bin/bash

Request 4x GPU along with 128x CPU cores for 24 hours

srun --partition=x86 --time=24:00:00 --nodes=1 --ntasks-per-node=128 --sockets-per-node=1 --cores-per-socket=64 --threads-per-core=2 --mem-per-cpu=4000 --wait=0 --export=ALL --gres=gpu:a100:4 --pty /bin/bash

2. Batch script


Access to overdrive

You need to submit an interactive job and/or batch script to request some resources to run your jobs.

1. Interactive

Request 1x GPU along with 40x CPU cores for 4 hours

srun --partition=arm --time=4:00:00 --nodes=1 --ntasks-per-node=40 --sockets-per-node=1 --cores-per-socket=40 --threads-per-core=1 --mem-per-cpu=3200 --wait=0 --export=ALL --gres=gpu:a100:1 --pty /bin/bash

Request 2x GPU along with 40x CPU cores for 4 hours

srun --partition=arm --time=4:00:00 --nodes=1 --ntasks-per-node=80 --sockets-per-node=1 --cores-per-socket=80 --threads-per-core=1 --mem-per-cpu=3200 --wait=0 --export=ALL --gres=gpu:a100:2 --pty /bin/bash
