Ravi Rajwar's Homepage
I have graduated from the Computer Sciences Department
at the University of Wisconsin-Madison.
My advisor was Jim
Goodman , a professor in the
architecture group at the University of Wisconsin-Madison.
I am now at Intel in Hillsboro, Oregon, working in product development.
Prior to being a graduate student, I worked for some time
at IBM Research in Yorktown Heights,New York.
I spent the summer of 1998 at Cray Research working on the coherence protocol of the SV2 system with Dr. Steve Scott, and the summer of 2000 at IBM Research working in the Scalable Server Division. A critical skill set developed during these summers was the appreciation of making and consuming good coffee.
I received a Bachelors degree in
Computer Science and Engineering (With Honors) from the University of Roorkee, Roorkee,
India, in 1994, a Masters degree in Computer Sciences from
the University of Wisconsin-Madison in 1998, and a Ph.D degree
in Computer Sciences from the University of Wisconsin-Madison in
Any computing system. I find many things
interesting. I dabble in microarchitecture, multiprocessing, threaded architectures,
future cache coherence protocols, memory system design, simulation
techniques, hardware verification techniques, parallelism, parallel software, memory ordering, and architecture/compiler
