Introduction

As a user of the Snakemake workflow management system, you may encounter issues when running your pipelines on a SLURM cluster. One such issue is the "SLURM account appears to be invalid" error, which can be frustrating and time-consuming to resolve. In this article, we will delve into the causes of this error, provide a step-by-step guide to troubleshooting, and offer potential solutions to get your pipeline running smoothly.

Software Versions

Before we dive into the troubleshooting process, let's take a look at the software versions used in this scenario:

Snakemake: 8.30.0
Snakemake Executor Plugin SLURM: 1.0.0
Snakemake Executor Plugin SLURM Jobstep: 0.3.0
SLURM: 24.05.3

Describe the Bug

When running a Snakemake pipeline with the SLURM plugin, you may encounter the following error:

No SLURM account given, trying to guess.
Guessed SLURM account: xyz
WorkflowError:
The given account xyz appears to be invalid. Available accounts:

The guessed account xyz is correct, but the error is thrown due to an issue with the command used to retrieve registered accounts.

Understanding the Issue

The reason for this error lies in the command used to retrieve registered accounts, which returns an empty list on your cluster. This is in contrast to the sshare command, which returns your accounts and could be used as an alternative.

Minimal Example

Unfortunately, a minimal example is not provided, as it is likely influenced by local SLURM configuration.

Troubleshooting Steps

To resolve the "SLURM account appears to be invalid" error, follow these steps:

Step 1: Verify SLURM Configuration

Ensure that your SLURM configuration is correct and up-to-date. Check the SLURM documentation for any changes or updates that may affect your pipeline.

Step 2: Check Account Availability

Verify that the guessed account xyz is indeed available on your cluster. You can do this by running the sacct command with the --format option to display the available accounts.

$ sacct --format=Account

Step 3: Use Sshare as an Alternative

As mentioned earlier, the sshare command can be used as an alternative to sacct to retrieve registered accounts. You can modify your pipeline to use sshare instead of sacct.

$ sshare -U

Step 4: Update Snakemake Executor Plugin SLURM

Ensure that you are using the latest version of the Snakemake Executor Plugin SLURM. You can update the plugin by running the following command:

$ mamba install -c conda-forge snakemake-executor-plugin-slurm

Step 5: Re-run the Pipeline

After making the necessary changes, re-run your pipeline to see if the error is resolved.

Conclusion

The "SLURM account appears to be invalid" error can be frustrating and time-consuming to resolve. By following the troubleshooting steps outlined in this article, you should be able to identify and fix the issue. Remember to verify your SLURM configuration, check account availability, use sshare as an alternative, update the Snakemake Executor Plugin SLURM, and re-run your pipeline. With these steps, you should be able to get your pipeline running smoothly on your SLURM cluster.
