Rezaul Chowdhury is currently involved in an NSF-funded project with Charles Leiserson and Steven Johnson of MIT on building a stencil computation compiler called "Pochoir". A stencil defines the value of a grid point in a d-dimensional spatial grid at time t as a function of neighboring grid points at recent times before t. Stencil computations are conceptually simple to implement using nested loops, but looping implementations suffer from poor cache performance on multicore processors. Cache-efficient divide-and-conquer stencil algorithms exist, but most programmers find them difficult to implement. Moreover, open problems remain in adapting these algorithms to realistic applications that lack the perfect regularity of simple examples. This research aims to develop a language embedded in C++ that can express stencil computations concisely and can be compiled automatically into highly efficient algorithmic code that will make good use of the memory hierarchy and processor pipelines endemic to multicore processors and will run fast on a diverse set of hardware platforms. A wide variety of stencil-based applications — ranging across physics, biology, chemistry, energy, climate, mechanical and electrical engineering, finance, and other areas — will become easier to develop and maintain. Some of his other projects focus on efficient resource-oblivious algorithms, fast energetics computation, and protein-protein docking.
