SLURM

All jobs on the general purpose cluster request resources via SLURM. SLURM, is open source software that allocates resources to users for their computations, provides a framework for starting, executing and monitoring compute jobs, and arbitrates contention for resources by managing a queue of pending work. SLURM is widely used in the high performance computing (HPC) landscape and it is likely you will encounter it outside of our systems. For more information please see https://slurm.schedmd.com/

General Purpose Computing

All resources on the general purpose cluster are submitted using the SLURM scheduler. For more information, please read the Frequently asked Questions. Jobs can be submitted from the following headnodes:

head.arcc.albany.edu
headnode7.rit.albany.edu

...

Or from the large memory machine:

lmm.

...

its.albany.edu

Resource information

All users have access to the "batch" partition for general purpose computing.

Info
The batch partition is comprised of 544 CPUs and 21 1040 CPU cores (2080 threads) and 31 compute nodes. Note that a job can only request 3 nodes and may only be active for 14 days. If you need an exception to this, please contact arcc@albanycontact askIT@albany.edu.

On a case by case basis, ARCC will ITS will grant users temporary access to more than the default job limitations. Please contact arcc@albanyaskIT@albany.edu if you would like to request access to more nodes, or a longer time limit.

Schedule a non-interactive job

...

There are many ways to schedule jobs via slurm. For non-interactive jobs, we recommend using sbatch with a shell script that runs your script. We will use #SBATCH commands to allocate the appropriate resources required for our script. Below is an example workflow of how to submit a python script via sbatch to batch.

First ssh into head.arcc.albany.edu. On windows, you can use an ssh client such as PuTTY, on mac, simply use the terminal. Replace [netid] below with your username and type in your password at the prompt. You will not see your password, but it is being typed.

How do I schedule an interactive job?

An "interactive" job means that you will have access to a terminal so that you can run "interactively" on the cluster. To achieve this, we will use srun. Interactive sessions are useful for debugging code, or making sure certain software compiles correctly.

First ssh into head.arcc.albany.edu. On windows, you can use an ssh client such as PuTTY, on mac, simply use the terminal. Replace [netid] below with your username and type in your password at the prompt. You will not see your password, but it is being typed.

Spawn on the infiniband nodes

You need to add the directive --constraint=mpi_ib

Code Block

language	bash

srun --partition=batch --nodes=2 --constraint=mpi_ib --time=01:00:00 --cpus-per-task=4 --mem=400 --pty $SHELL -i

OR

Code Block

language	bash

#SBATCH --constraint=mpi_ib

Allocate GPU resources

You can request access to the GPUs on --partition=ceashpc by adding the following flag:

--gres=gpu:1 # For half of the K80

--gres=gpu:2 # For the full K80

To request access to the A40s on the batch cluster for your research lab, please email askIT@albany.edu.

Once your group is added you can request access to the GPUs on --partition=batch-gpu by adding the following flag:

--gres=gpu:1 # For one of the A40s

--gres=gpu:2 # For two of the A40s

etc.

Run jupyter notebook on the cluster

There are two ways to spawn jupyter notebooks on the server:

https://jupyterlab.arccits.albany.edu ; please see How-to: Using Jupyterhub for more information

If you need more resources, or longer than an eight hour time limit, you can run jupyter notebook interactively

First, ssh into head.arcc.albany.edu and run; then enter a password at the prompt (note that you will not see your password, but it is being registered)
Code Block
language bash
/network/rit/misc/software/jupyterhub/miniconda3/bin/jupyter notebook password

Next, you can either run jupyter notebook interactively with srun, or you can submit the process via sbatch script located at /network/rit/misc/software/examples/slurm/spawn_jhub.sh (see below)

Spawning jupyter notebook interactively using ARCCITS's anaconda (you may change the path to your own conda distribution)

Code Block

language	bash

srun --partition=batch --nodes=1 --time=01:00:00 --cpus-per-task=4 --mem=400 --pty $SHELL -i
unset XDG_RUNTIME_DIR
/network/rit/misc/software/jupyterhub/miniconda3/bin/jupyter notebook --no-browser --ip=0.0.0.0

You should see a jupyter output related to launching the server. Once it is complete, you should see output that looks like:

Code Block

language	bash

[I 08:31:49.694 NotebookApp] http://(uagc19-02.rit.albany.edu or 127.0.0.1):8889/
[I 08:31:49.694 NotebookApp] Use Control-C to stop this server and
shut down all kernels (twice to skip confirmation).

Open up a web browser and navigate to the suggested location, in the example we would navigate to uagc19-02.rit.albany.edu:8889 , enter the configured password at the prompt, and that you are all set!

Spawning jupyter notebook via sbatch using ARCCs ITSs anaconda (you may change the path to your own conda distribution):

ssh into head.arccits.albany.edu and copy the file below to your home directory and submit the script with sbatch.

Code Block

language	bash

# Copy the file
cp /network/rit/misc/software/examples/slurm/spawn_jupyter.sh ~/spawn_jupyter.sh
 
# change the directory to the home directory
cd ~/
 
# submit the script
sbatch spawn_jupyter.sh

Info
Note that you will want to edit the script to request the amount of resources that you need

This script will create an output file called juptyer.[jobid].log. Open up this file, replacing [jobid] with the allocation number you were given (you can get this by looking at squeue) and you will see output that looks like:

Code Block

language	bash
firstline	1
linenumbers	true

[I 10:06:31.780 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

Open up a web browser, and point to the location noted in the second to last line, in the above example, http://uagc12-02.arcc.albany.edu:8888, enter your password, and you are all set!
