Strange encounters of the Non-symmetric kind

Aftab Patel

Advisor: Prof. Edmond Chow

ABSTRACT

Finding factorized pre-conditioners for sparse non-symmetric matrices has long been known to be a hard problem to tackle. The talk will highlight some new approaches to solving this problem. The first part of the talk will be a chalk talk highlighting the problem and the various ways in which its solution can be approached. The second part will present experimental results comparing various techniques and highlighting some of the inherent difficulties associated with preconditioning for general matrices.

BIO

Aftab Patel obtained his Masters and Bachelors degrees in Mathematics and Computing at the Indian Institute of Technology at Kharagpur in India in 2012. Since then he has been a PhD student at the School of Computational Science and Engineering working under the advise of Prof. Edmond Chow. In the past Aftab has been involved in developing high-performance algorithms for Computational Quantum Chemistry. Aftab currently works on developing new algorithms for preconditioning with a focus on algorithms that have a good potential for efficient implementation on modern many-core parallel architectures.
