Kim McMahon received her B.S. (1987) in computer science from the University of Wisconsin, Eau Claire. She has accumulated over 30 years of experience in HPC, working at ETA systems, SGI, Cray and HPE. She is currently a master systems software engineer at HPE. Kim has spent her career optimizing low-level HPC communication libraries, specializing in MPI and SHMEM. Her main interests are designing highly efficient communication algorithms that allow scaling to millions of processes, as well as diagnosing complex low-level performance and scaling bottlenecks in both systems and applications.
