NAMD Performance Study

NAMD is written in charm++ and thus has some unique attributes when profiled by TAU. For example charm++ scheduler which assigns task to processors and helps in load balancing the program has a notion of Idling while waiting for tasks to complete. TAU thus creates a event to capture time spent when the scheduler is in its idle state (Idle) as well as a event (main) to account for the communication latencies.
