It is a sunny morning in the computer architecture research community. In the last few years, our community has multiplied in size, our conferences consistently reach record-high attendance, and the number of active research areas is mind-boggling. Members of our community are recognized with the Turing Award and are leading NSF CISE. While times may be exhilarating, it is important that all of u…

One of the most pressing challenges facing today’s digital society is how to curb the relentless increase in the energy consumption of computing. Without major action, such an increase is even likely to accelerate, as ubiquitous AI models are embedded

Machine learning-driven computer architecture tools and methods have the potential to drastically shape the future of computer architecture. The question is: how can we lay the foundation to effectively usher in this era? In this post, we delve into the

In this blog post, we highlight recent publications from the IEEE Computer Architecture Letters (CAL) from the IEEE Computer Architecture Letter Vol. 21 (Issue1  •  Jan-Jun2022).  We include a short summary if provided by the authors.   IEEE CAL Editorial Board

With deep sadness and great sorrow, we inform the community about the recent passing of our dear friend and colleague, Professor Michel Dubois, a foundational leader in our field of computer architecture and parallel processing. Michel earned his Bachelor’s degree

Scientific progress relies on sound reviewing processes.  The integrity of our review process is paramount, and it rests on our handling of ethical concerns and conflicts of interest.  These issues have been compounded by the rapid growth in the computer

This is a repost from the ACM SigArch blog. Welcome to the trip report on the 28th IEEE International Symposium on High-Performance Computer Architecture (HPCA-28)! This marks the second fully-virtual HPCA (and hopefully last). With signs of the COVID-19 pandemic

1: What is Superconductor SFQ? Moore’s Law, doubling the number of transistors in a chip every two years, has so far contributed to the evolution of computer systems. Unfortunately, we cannot expect sustainable transistor shrinking anymore, marking the beginning of

With MICRO upon us, I would like to take time to reflect on the events running up to the establishment of CASA or the Computer Architecture Student Association. This month we will be celebrating our first anniversary as an active

Dear Computer Architecture Community, We take this opportunity to invite you all to the first-ever edition of the IEEE International Symposium on Secure and Private Execution Environment Design (SEED). This blog post will provide an overview of the inaugural edition of IEEE

Across the computer systems and architecture community, there has been A Call to Action to advance and promote diversity, equity, and inclusion (DEI) values through systemic change. Towards this step,  HPCA 2021, PPoPP 2021, CGO 2021, and CC 2021 held

As with all scientific communities, the field of computer architecture is driven by publications. At the heart of a meaningful scientific publication model is a fair and sound peer-reviewing process. If this process is compromised, some papers might be unfairly

Welcome to the trip report on the 27th Annual (and the first virtual/global online) IEEE Symposium on High Performance Computer Architecture!  The conference marks one full year of virtual keynotes, panels, talks, and networking, for many of us, since the last

This article also appears on the ACM’s Committee for Systematic Change webpage (https://www.acm.org/diversity-inclusion/committee-on-systemic-change) and the IEEE CS Diversity & Inclusion webpages (https://www.computer.org/about/diversity-inclusion). There is a movement occurring broadly across many scientific and engineering fields, including widely within our computing community,

Dear Computer Architecture Community, This blog is to provide an overview of the HPCA 2021 PC organization and the paper selection process. As you all know by now, HPCA 2021 will be virtual. So, let me take this opportunity to
