How do I know Non-uniform Memory Access (NUMA) layout on Brown?
- You can learn about processor layout on Brown nodes using the following command:
brown-a000:~$ lstopo-no-graphics - For detailed IO connectivity:
brown-a000:~$ lstopo-no-graphics --physical --whole-io - Please note that NUMA information is useful for advanced MPI/OpenMP/GPU optimizations. For most users, using default NUMA settings in MPI or OpenMP would give you the best performance.
