Biography

My research focuses on run time systems and programming models for high performance computing, including issues in productivity, scalability, and power. Much of my work concerns support for efficient multithreading on the supercomputer node level, especially through the task-parallel programming model. I enjoy working with application and library developers to improve the scalability of their codes and to take advantage of multicore and manycore architectures, and I represent Sandia Labs on the OpenMP Language Committee and Architecture Review Board.
