HPC Systems Architect

National Energy Research Scientific Computing Center

Lawrence Berkeley National Laboratory


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.

Data-Intensive Computing

The following pages document some of the different faces of data-intensive scientific computing in which I've worked over the last few years. I haven't used Hadoop or R since I left the San Diego Supercomputer Center in 2014, so those guides may seem a bit dated now.

Practical Data Analysis

Topics in Storage

Topics in Hadoop

Parallel Computing with R

HPC Howtos

In the past I have worked as both a user services consultant and a systems engineer. This section contains a few notes relevant to using and managing HPC resources, but the bulk of my HPC how-to guides remains hosted at the San Diego Supercomputer Center.

Performance & Benchmarks

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

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.


I've created the following pages about my hobbies mostly for my own entertainment. They have little to do with what I do professionally, but they might be of interest to people who hold similar interests.
