Jiménez and collaborator receive $550k NSF grant




The National Science Foundation has awarded a $550,000 grant to support Daniel Jiménez and Emery Berger's collaborative research towards making computer system performance reliable. Dr. Jiménez is an associate professor in the Department of Computer Science at the University of Texas at San Antonio, and Dr. Berger is an associate professor at the University of Massachusetts Amherst.

Modern computer systems are plagued by performance variance, a phenomenon where seemingly unimportant features of a program can result in pathological reductions in performance. The investigators are designing and evaluating the use of randomized algorithms in both software and hardware, separately and in combination, to remedy the numerous sources of pathological behavior in modern systems. The result will enable performance-portable applications that are immune to unfortunate interactions with microprocessor and memory system components.
