I am a high-performance computing systems architect at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. NERSC provides high-performance computing resources for thousands of researchers around the world each year, and my role is to ensure that our storage systems balance advanced technologies with production reliability to enable science that can be done nowhere else. To this end, my work focuses on I/O performance analysis, extreme-scale storage architectures, and emerging I/O technologies and interfaces.

I have worked in the genomics industry in the past, and my formal education is in ceramic engineering. More information about my current and past work can be found in my CV and on LinkedIn, and excruciating details about my life are in my biography.

This site contains various notes I've taken related to technical computing over the years. I welcome any feedback about its contents at the e-mail address listed at the bottom of every page. You can also find me on Twitter and in the #hpc channel on freenode.

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 I try to retire links to pages once they have fallen out of date, so things tend to come and go from this section as technologies (and my areas of work) evolve.

Practical Data Analysis

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Computing with R that I host for posterity, but I haven't used either of these since 2014 and those guides are likely out of date.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.

Electronics

System & OS Configuration
