Laxmikant Kalé received his Ph.D. from the State University of New York at Stony Brook in 1985. He is a professor in the U of I Department of Computer Science and a part-time faculty member in the Beckman Institute Theoretical and Computational Biophysics group. His primary research interests include parallel computing with emphasis on irregular and dynamic applications, and development of parallel objects technology.
Runner up for Gordon Bell Award, Supercomputing (2000); Gordon Bell Award, Supercomputing (2002); Best Poster Award, Supercomputing (2002); Fellow, IEEE; HPCC Challenge Class 2 Award, Supercomputing (2011); Sidney Fernbach Award, IEEE (2012); Finalist, HCP Challenge Class 2 Competition, Supercomputing (2012).
Kalé's work is aimed at improving performance and productivity in parallel programming. He pioneered the development of object-based parallel programming (via the Charm++ system, and its precursor, the chare kernel).
Although a large number of early parallel applications have been highly regular in structure, and could be parallelized easily using extant approaches, many emerging applications manifest irregular structure as well as dynamically changing structure. Development of effective techniques for efficient parallelization of such applications, without excessive programming effort, is a primary goal of his research.
Data-driven objects, embodied in Charm++, provide an effective substrate for such techniques. A programmer divides the parallel competition into a number of interacting objects, while the Charm++ system manages the placement and scheduling of these objects, migrating them when necessary. This creates an almost optimal division of labor between the human programmer and the automated runtime system, each being responsible for the part it can do best.
Kalé is engaged in a collaborative research project at the Beckman Institute with professors Schulten and Skeel. A specific research project involves development of a parallel molecular dynamics program, named NAMD2. Using Charm++, and other techniques developed in Kalé's research, this program runs on all available parallel machines and workstation clusters, and is in production use by scientists. This program has demonstrated highest speedups, 180 on 220 processors, of any production-quantity molecular dynamics program to date. Kalé is also involved in the development of a synchronous/asynchronous collaboratory for molecular dynamics. More information about his research can be found at http://charm.cs.uiuc.edu.
