How much memory do my jobs get? How do I assign more memory for a job?

Each ‘core’ comes with 4GB RAM (cells E-K) and 8GB RAM on cell M.

In you PBS script, you can specify the number of nodes and cores your job will require:

#PBS -l nodes=1:ppn=4

In this example, my job will be assign one node and 4 cores => 4x4GB=16GB RAM if it runs on cells E-K and 4x8GB=32GB on cell M.

Note that even you job does not need more than 1 core, but need more RAM, you must request the appropriate number of cores which might remain unused.
