Date: Wed, 24 Apr 2002 18:40:04 -0500 (CDT) From: Yale Patt This is to apologize for wasting your time waiting for me today. American Airlines was supposed to get me back in plenty of time to make it to class just after you filled out the evaluations. Unfortunately, an American airlines scheduling problem (no excuse for that) got us started late and the weather in the midwest (not American's fault) got me back 1 1/2 hours later than they were supposed to. Again, I apologize. I will see some of you between now and class on Monday. Class will meet on Monday, per usual. Guest lecture by Ron Kalla of IBM on the microarchitecture of their Power 4 chip, the design decisions they were faced with, and hopefully he will share with us some of the hindsight he has developed as a result of that project.
