Welcome to the CCV Oscar User Manual. Oscar is Brown University's supercomputer.
This user manual assumes you already have an Oscar account. If you do not have an Oscar account, you can request one by filling and submitting a new user account form.
Anyone with a Brown account can get a free, exploratory account on Oscar.
Individuals external to Brown can get access to Oscar by having a sponsored Brown account. Please work with your department to get sponsored Brown accounts for any external collaborators.
Do not run computations or simulations on the login nodes, because they are shared with other users. You can use the login nodes to compile your code, manage files, and launch jobs on the compute nodes.
Large numbers of jobs submitted to Slurm on Oscar can cause problems. If you are going to submit tens of thousands of jobs please bundle your work into fewer jobs. CCV staff can help you with this. Please email email@example.com with any questions
Oscar is a multi-node system. If your code is serial or threaded then using multiple nodes will not make your code go faster. Restrict your job to running on one node with#SBATCH -N 1. Efficient use of resources helps everyone on Oscar. CCV staff can help you determine the best way to run your job. firstname.lastname@example.org
