OLCF Performance Analysis (Hands-On) Tutorial
Oak Ridge National Laboratory, Building 5100 – Room 128 (JICS Auditorium)
February 20th, 2018
9:00 AM – 5:00 PM


The Oak Ridge Leadership Computing Facility (OLCF) will host a Hands-On Performance Analysis Tutorial for OLCF users interested in speeding up their applications.

Attendants will receive an introduction to HPC performance analysis, and specific instructions on how to leverage Vampir, Arm MAP and Arm Performance Reports. For the majority of the time attendants will investigate and improve the performance of their own application or work on prepared examples with the help of mentors who have experience using Summit-dev and the profiling tools.

This event is targeted for teams of users with applications currently running on Summit-dev.

Arm Performance Reports is an easy-to-use, high-level tool that generates a one-page report on where your parallel program run spends its time.

Arm MAP is a profiling-based tool that provides detailed execution information along with performance metrics and system utilization statistics.

Vampir relies on instrumentation to provide the greatest detail of these tools. It lets you investigate what each process, thread and GPU stream is doing at all times and for that provides a scalable analysis engine and interactive GUI to explore your application run.

Workshop attendance is strictly by invitation only.  If you have received an invitation by email please form a team who will attend and have them register. All off-site, non-badged participants must register by January 20th.

Questions should be directed to Ronny Brendel (brendelr@ornl.gov) and Tom Papatheodore (papatheodore@ornl.gov).
