Data Intensive Sci Computing
As a research scientist within the Center for Adaptive Supercomputing Software, or CASS, Dr. Morari is part of the PNNL team designing the PNNL Graph Engine for Multi-threaded Systems (GEMS). GEMS is based on the PNNL Global Memory Multi-threaded (GMT), a runtime system Dr. Morari and other scientists designed and developed to efficiently execute irregular applications on large-scale distributed systems.
In addition, Dr. Morari has contributed to several conference papers and journal articles. He has served as a program committee member and as a reviewer for several international conferences.
Prior to joining PNNL, Dr. Morari was a resident student at Barcelona Supercomputing Center and a research intern at the IBM T.J. Watson Research Center.
