Robert Wisniewski, URCS Alumni
Current Employment
I am currently working at IBM's
T. J. Watson Research Center where I am exploring issues involved in
the design of scalable, portable, and configurable next generation
operating systems. See my home page there or K42's page, the
project I am working on. Prior to this and after receiving my PhD I worked
at Silicon Graphics on high-end parallel OS development, parallel real-time
systems, and real-time performance monitoring.
Research Interests
My research interests lie in experimental parallel systems with the goal of
achieving high performance by cooperation between the system and the
application. Specifically, I am looking at the performance and
programmability benefits that can be gained in parallel real-world
applications by sharing information in a domain independent manner across
the application - system interface. I am interested in mechanisms for
monitoring such systems to provide programmers with information to allow
higher performance applications to be developed and performance tuned more
easily. I am also interested in exploring techniques for
scheduler-conscious synchronization, using scheduler-provided information
to provide high performance synchronization primitives.
