How do I know Non-uniform Memory Access (NUMA) layout on Data Workbench?
- You can learn about processor layout on Data Workbench nodes using the following command:
- For detailed IO connectivity:
workbench-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.
