Principal Technical Strategist

VAST Data

I am a Principal Technical Strategist at VAST Data where I maintain an understanding of where HPC/AI technologies are headed to help people, both inside and outside of VAST, make decisions about the future. In practice, my job involves a mix of talking to practitioners to understand their workloads, analyzing new technologies to understand their capabilities, and sharing what I've learned in whatever ways make sense to people facing uncertainy and tough challenges.

Before joining VAST, I was a Principal Engineer at Microsoft where I supported the design and operations of the largest AI supercomputers being built in Azure. Prior to that, I was a systems architect at the National Energy Research Scientific Computing Center (NERSC) where I focused on storage and data research and designed a couple of large, high-performance storage systems.

More information about my current and past work can be found on Google Scholar and in my biography.

This site contains my notes in technical computing from over the years. Older notes and blog posts are linked below, but I have started moving my personal notes to my digital garden which I update continuously.

To get in touch, send me an email or contact me via Bluesky, Mastodon, or HPC.social chat.

High-Performance Computing

I've worked in high-performance computing since 2012, and this section contains notes and guides I've written in that capacity. I try to retire links to pages once they have fallen out of date, so things tend to come and go from this section as technologies (and my areas of work) evolve.

Artificial Intelligence

Cloud Computing

High-Performance Storage

General HPC

Performance & Benchmarks

This section contains a number of disjoint pieces revolving around performance analysis.

I also have a set of pages on Hadoop and Parallel Computing with R that I host for posterity, but I haven't used either of these since 2014 and those guides are likely out of date.

Materials Science

When I was a student I maintained a variety of notes about different topics relevant to ceramic engineering, in which I got my undergraduate degree. I've re-uploaded them here for posterity.

Hobbies & Personal Stuff

This section contains notes and tutorials that I've written related to my personal interests and hobbies outside of work.
