Now in its ninth year, ACSAC continues to provide an excellent forum for researchers, educators and practitioners to come to the Asia-Pacific region to exchange ideas on the latest developments in computer systems architecture. This year, the paper submission and review processes were semiautomated using the free version of CyberChair. We received 152 submissions, the largest number ever. Each paper was assigned at least three, mostly four, and in a few cases even five committee members for review. All of the papers were reviewed in a twomonth period, during which the program chairs regularly monitored the progress of the review process. When reviewers claimed inadequate expertise, additional reviewers were solicited. In the end,
