Praveen Narayanan has been working on performance characterization and benchmarking of several parallel applications running at NERSC in order to gauge their performance. His efforts have so far included benchmarking of fusion applications developed by researchers from several institutions, performing workload characterization of applications running at the now retired Magellan cluster, and developing compact applications to demonstrate certain specific performance aspects of larger applications.
Narayanan earned a PhD from the University of Maryland, College Park. His research dealt with understanding non-premixed flame extinction using high performance computing and analytical means. Although he is new to NERSC, Narayanan has been using the facility's system for the past five years.
"I feel like a fish in water in my current position because of my interests in applied mathematics, computing and engineering. The environment could not be more favorable," says Narayanan. "The Berkeley Lab is filled with people who are experts in these aspects, from people who can devise efficient algorithms to solve differential equations, to people who can build systems that can run extremely scalable codes, and people who bring insight using assorted techniques such as data mining, experiments and mathematical analysis of governing equations."
Originally from India, Narayanan has lived in Delhi, Ranchi, Chennai and Bangalore. He came to the United States to pursue a doctorate degree in mechanical/fire protection engineering that the University of Maryland, College Park. In his spare time, Narayanan enjoys playing chess, bicycling, listen to Carnatic and western classical music, and reading.
