Summary: Robert McLay manages the software tools group in high performance computing at the Texas Advanced Computing Center. Dr. McLay is one of the developers of XALT, a software tool developed with funding by the National Science Foundation. XALT tracks user codes and environments on a computer cluster. Robert McLay and Mark Fahey of the Argonne National Laboratory will be co-leading a session called "Understanding User-Level Activity on Today's Supercomputers with XALT" at SC15. The SC15 supercomputing conference takes place in Austin, November 15-20, 2015. SC15 showcases the latest in high performance computing, networking, storage and analysis to advance scientific discovery, research, education and commerce. Robert McLay: XALT is a tool that me and my colleague, Dr. Mark Fahey, put together to help people try and use our systems. We run the system. We manage the system. We develop software for the system and install software for our users. We want to know what's used and what's not. XALT gives us a way to find out in a very inexpensive way.
