Abstract :
A productive, healthy debate is informative and insightful, and collectively moves the debaters and the audience closer to a potential solution or agreement by examining the issues from multiple viewpoints and critiquing those arguments. Micro editor in chief David Albonesi introduces four debates on computer architecture from the Computer Architecture Research Directions (CARD) workshop that was held as part of the 13th Annual IEEE/ACM International Symposium on High-Performance Computer Architecture in February 2007.
