TITLE:		FEAST Eigensolver:
 		Breakthrough, Challenges and Opportunities


SPEAKER:	ERIC POLIZZI  (University of Massachusetts, Amherst)


ABSTRACT:

The FEAST solver (www.feast-solver.org) is a new open source numerical 
library for solving the eigenvalue problem, which has also been recently 
integrated into the INTEL-MKL library. The solver is based on an 
innovative numerical algorithm - the FEAST algorithm - which represents a 
departure from textbook approaches for solving the eigenvalue problem. 
FEAST is using elements of complex analysis, numerical linear algebra and 
approximation theory, to offer a set of important capabilities for 
achieving high-performance, robustness, accuracy, and potential for linear 
scalability on parallel architectures.  Since the first FEAST publication 
in 2009, we have been working on (i) establishing a solid mathematical 
foundation for the algorithm that successfully demonstrates its fast 
convergence property [SIAM. J. Matrix Anal. & Appl. 35, 354 (2014)]; (ii) 
advancing the algorithm development to broaden the class of eigenvalue 
problems that can be addressed (e.g. non-Hermitian and non-linear); as 
well as (iii) enhancing its multilevel parallel performances to achieve 
load balancing on high-end computing platform.  Finally, we will also 
discuss how FEAST has considerably broaden the perspectives for enabling 
reliable and high-performance first-principle electronic structure 
calculations with applications in computational material nanosciences and 
device nanoengineering.
