"Research"
Are you doing research that involves simulating multi-program workloads? If you are, you might want to consider using FIESTA as your workload construction methodology. FIESTA is simple, makes it possible to directly compare different multi-program experiments, and yields un-skewed, easy to interpret results. We are currently working to extend FIESTA to multi-threaded applications and on a SimPoint-like tool that will generate individually representative FIESTA workloads. We welcome any comments you may have on FIESTA.

Research
My research interests are in the broad area of computer architecture and in the somewhat narrower sub-area of microprocessor and memory system design. My students and I are part of the architecture and compilers group (ACG) which I co-lead with Prof. Milo Martin. Here is a list of my current and former PhD students and the projects they are working on:

• Andrew Hilton (May 2010)
  Dissertation: Energy-Efficient Latency Tolerance: Single-thread performance for the Multi-Core Era
  First employment: IBM (Research Triangle Park)
  
  
• Tingting Sha (May 2009)
  Dissertation: Reducing Load Datapath Complexity Using Memory Dependence Prediction
  First employment: nVIDIA (Portland)
  
  
• Anne Bracy (November 2008)
  Dissertation: Mini-Graph Processing
  First employment: Intel Corporation (Santa Clara)
  Current employment: Washington University in St. Louis
  
  
• Vlad Petric (December 2007)
  Dissertation: RENO
  First employment: Google (Manhattan)

Teaching
This Semester I am teaching CIS 240: Introduction to Computer Systems. Here are some other courses I have taught:

• CIS 240: Introduction to Computer Systems (Fall 2008, 2009)
• CIS 501: Introduction to Computer Architecture (Fall 2001, 2002, 2003, 2004, 2006, 2007)
• CSE 371: Digital Systems Organization and Design (Spring 2004, 2005, 2006, 2007)
• CSE 372: Digital Systems Organization and Design Lab (Spring 2004, 2005, 2008, 2009)
• Advanced Topics in Computer Architecture (Spring 2002, 2003)

Starting Jan. 2009, I am the undergraduate chair of the Computer and Information Science Department. Kids, meet the new boss.

Quasi-Personal
I've been told that I am "unapproachable". Indirectly, of course. Nobody will approach you and tell you that you are unapproachable. Well, baloney. I'm just a regular guy.

• I am a father of two and a husband of one (thanks Hunt). My wife is a program officer at Pew Charitable Trusts. My children are unemployed. Free-loaders.
• I like to keep a reading list to remind/encourage myself to read for fun.
• I also have a blog (good luck finding it)
• I like the Philadelphia Eagles. Maybe a little too much.
• I like snowboarding.
• I love to travel. The best place I have ever been is Galapagos Islands.
• I do volunteer work for an environmental organization.
• My favorite Philly restaurants are Alma de Cuba and Alyan's.
• I was born in Israel and I speak Hebrew (not all the time).
• I am thinking (not that seriously) about buying a motorcycle.
