With Titan’s arrival, fundamental changes to computer architectures will challenge researchers from every scientific discipline. Members of the OLCF’s Application Performance Tools (APT) group understand the challenge. Their goal is to make the transition as smooth as possible.

In this interview Rich Graham, group lead for the OLCF’s Application Performance Tools Group, discusses the challenges presented by new hybrid computer architectures such as Titan’s.
