Frequently Asked Questions

For setup, follow Quick Start. For unresolved problems, contact support.

Access

Dashboard registration does not grant compute access. Check your project membership and allocation, including its expiry date.

Why is Remote accounts empty?

This is normal before provisioning. If you were notified that access is ready, check your account and contact support if it is still missing.

Why can I not add team members?

Only a Project manager can manage membership. See Project Administration.

SSH says “Permission denied (publickey)”. What should I check?

Check your HPC username, active allocation, and that your client uses the private key matching your registered public key. See Login.

Which account do I use with multiple projects?

Use the account of the project you want to charge. See Username and Slurm account.

Software and Jobs

Can I use an executable built on my laptop?

An x86-64 executable will not run natively on ICARUS's Arm CPUs. Compile for ICARUS and its available libraries.

Why is a compiler command missing?

Load the required software module in your current shell and in the batch script.

Why does mpicc report the nvc version?

mpicc invokes the configured C compiler, which is nvc in this stack. Use mpirun --version for the MPI version. See Compilers.

Can my job download datasets?

Compute nodes have no internet access. Transfer files through a login node before submission.

Will my batch job stop if I disconnect?

No. A job accepted by sbatch continues under Slurm. Reconnect to check its status.

Why is my job pending?

Check the reason in squeue -u "$USER". See pending reasons; resubmitting does not improve priority.

My job was rejected or timed out. What next?

For rejection, check the error, account, and resource limits. For timeout, adjust the requested duration within those limits and use application checkpoints where supported.

Where are my logs and resource statistics?

Check the output paths and Job Accounting. Missing GPU metrics do not imply zero usage.

Data and Allocations

Are files backed up or retained after expiry?

Read Data Retention and keep independent copies of important files.

How do I request more time?

Coordinate with your PI and follow Check Usage and Request an Extension.

Can I create a training project now?

Request Resources is a future feature. Current research access uses Calls and Project Proposals.
