SMP Cluster Overview¶
The SMP nodes are appropriate for programs that are parallelized using the shared memory framework. These nodes are similar to your laptop but with more CPU cores and shared memory space between them.
Key Features¶
- high memory partition for nodes with up to 3 TB of shared memory
