Professor Skjellum received his BS, MS, and PhD Degrees from Caltech. His PhD work emphasized portable, parallel software for simulation, with a specific emphasis on message-passing systems. After graduating in 1990, he worked at Lawrence Livermore National Labs for 2.5 years as a computer scientist emphasizing performance-portable message passing and portable parallel math libraries. From 1993-2003, he was on faculty at Mississippi State University, where he and his students co-developed MPICH with Argonne National Laboratory, the first implementation of the MPI-1 standard. Skjellum was a leading participant in MPI-1 and MPI-2 standards as well, with specific contributions to the concepts of “groups contexts, and communicators,” which stemmed from his PhD research. From 2003-2013, he was professor and chair at the University of Alabama at Birmingham, Dept. of Computer and Information Sciences, where he continued work on high performance computing and cyber.
