procrastination

You may notice that I did not officially graduate from Illinois until January 1997, and probably wonder what's up with this?? Well, I really finished in 1994 as I passed my final defense in November 1994, but I left to join HP without completing my dissertation (big mistake!). To make a long and somewhat painful story short, it took me 2 years to finish the writing after I left (1.9 years of procrastination and 0.1 years of writing). So, I did not officially get my diploma until January 1997.  I still get ribbed about this today by David August and others who helped me turn in my dissertation.

Work experience

I worked in industry for six years before coming to Michigan. Interestingly, I interviewed in the EECS Department at Michigan in 1994, and had an offer to join. But, I decided that I wanted to work in industry for a while to see what the real world was like. So, I joined the Compiler and Architecture Research Group at Hewlett-Packard Laboratories in Palo Alto, CA headed by Bob Rau. I was there from 1995 to 2001.  Here are some of the projects I worked on when I was at HP:

  • Compilation for Explicitly Parallel Instruction Computing Processors - The group developed a prototype compiler backend targeted to processors similar to the IA-64. Some of the things I worked on include if-conversion, region formation, instruction scheduling, control/data height reduction optimizations, and synthetic branch prediction.
  • Trimaran - Together with the IMPACT and CREST research groups, we released a compilation infrastructure known as Trimaran to facilitate ILP compiler research.  Trimaran is still used today by many research groups including my own.
  • PICO - In 1997, my group at HP shifted focus from IA-64 to embedded processors, where we focused on automatic design of custom embedded processors and hardware accelerators. PICO, or Program-In Chip-Out, is the name of our prototype system.  Several members of the PICO team left HP and started a company called Synfora to productize the PICO technology.

Prior to 1995, I was a graduate research assistant at the University of Illinois at Urbana-Champaign. I worked with Prof. Wen-mei Hwu and helped create the IMPACT compiler.  You may notice that I did not officially graduate from Illinois until January 1997, and probably wonder what's up with this??
