Enjoyed speaking about AI, datacenters, and sustainability as part of Penn Energy Week. Wonderful to be part of a broader community at Penn studying these questions. See Energy Week.

21 Feb 24

The development and growth of computer architectures for AI is only just beginning, but excitement about NVIDIA persists. See PYMNTS.

15 Feb 24

Investments in renewable energy and grid infrastructure are essential, but induce persistent inflation in electricity prices. See Yahoo Finance.

Carbon Explorer -- our framework for carbon-aware datacenter design -- has been recognized by an IEEE Micro Top Picks, Honorable Mention. Congratulations to Bilge Acun and team! See the paper for more.

16 Jan 24

Sustainable datacenters require increasingly sophisticated decisions that balance site selection, availability of carbon-free energy, and impact on local communities. See Business Insider.

20 Dec 23

Excited to see the growing community in machine learning for computer architecture and systems. A recent workshop has integrated varied perspectives into directions for future research. See blog post.

7 Dec 23

Building bridges between computing and policy during a workshop on sustainable AI. Enjoyed connecting with the Kleinman Center for Energy Policy and the Penn Program on Regulation. See YouTube.

Exciting to see the breadth of industry activity in datacenter computing for AI. It is early days yet. See Silicon Angle.

30 Nov 23

The growth of AI increasingly raises questions about sustainability and regulation. Prof. Cary Coglianese and I explore the issues from legal and technical perspectives. See link.

29 Nov 23

Elected IEEE Fellow for contributions to the design of microprocessors with machine learning and game theory! Grateful to mentors, collaborators, and the research community for supporting this work.

29 Nov 23

Despite advances in the 2000s, power and thermal management remain pressing challenges. Enjoyed commenting on these fundamental questions with IEEE Spectrum.

20 Nov 23

Concerns about AI energy usage are driven, in part, by a large and growing gap in datacenter energy usage and renewable energy installation. See Recharge News.

10 Nov 23

We were excited to launch the inaugural PhD Forum at MICRO last week. If you are looking to hire a computer architect, please consider the forum's participants here.

23 Oct 23

Data centers should schedule their energy use, looking beyond batch jobs and bitcoin mining, which offer flexibility but not at scales needed to align large datacenter demand with intermittent carbon-free supply. See S&P Global Podcast.

16 Oct 23

Growth in data centers is likely to outpace that in renewable energy deployments, requiring new strategies to reduce operational carbon. See Yahoo Finance.

10 Oct 23

Excitement about AI has implications for computer systems, architectures. While there is uncertainty about growth rates and energy costs, numbers are large and require sustainably scaling data center infrastructure and semiconductor manufacturing. See New York Times.
