+# Based on the list of gpus entered by the user, the script finds the numa nodes associated with each of the gpus, and runs the tool with sources as the numa nodes and destinations as the gpus (h2d) and then with sources as the gpus and destinations as the numa nodes (d2h) with the user entered message sizes
