The information on this web page is out of date now. As of April 2009, I and the rest of the DICE team left SDSC and either joined the Institute for Neural Computation at UCSD or moved to the University of North Carolina. I'm now the team-lead for DICE-UCSD in INC. My current email address is email@example.com. Other more current information about me can be found here.
I'm a member of the SDSC Storage Resource Broker ( SRB)/ Data Intensive Cyber Environments ( DICE) group, and a Senior Data Grid Programmer/Analyst. Most recently, since late 2005, I've been a principal co-developer (with Mike Wan and Dr. Arcot Rajasekar) of iRODS, our rule-oriented replacement for SRB, developing the catalog sofware (ICAT), administration, installation, and authentication software, etc. Prior to this, my main development areas have been in SRB administration (the Java admin tool), installation improvements (perl scripts), assisting in core development (ZoneSRB, etc), security (GSI authentication, encryption/compression), integration projects (MDSPlus, SRM), testing, documentation (papers, FAQ, internal documentation), and other support tasks. SRB is a system that helps researchers manage large collections of data distributed spread around the world (see "What is SRB?"). SDSC provides access to supercomputing resources (big/fast computers) and software to researchers across the country.
I've been an SRB team member since September 2002, when I returned to SDSC after working for Entropia for a little more than two years. Before that I was with SDSC from near the start (1985) working in various roles and on many software development projects. For more on that, see my old home page.
At Entropia I helped create the Scheduling system that runs as part of Entropia version 5.0 and 5.1. It was a lot of fun (for the most part), and an intestesting experience. I got to work for a startup (with the pluses* and minuses of that), with Windows (altho I like Unix better), and with another group of talented and hard-working people. Entropia, like SDSC, was supporting large-scale computational science, and I was (and am) enthused about that and the potential of large-scale Grids of PCs. This is a difficult market tho, and after 4 rounds of layoffs, I decided it would be best for me to return to SDSC. Had Entropia been successful, it would have been hard to decide between the two, as there is much I like (and a little I don't) about each. *Of course, one of the big potential pluses of a startup are the stock options, which didn't work out in this case (I chose not to buy mine and they have now expired).
I was with SDSC since it started in 1985, and have been involved in many projects , many of which have been described in various publications . I was manager/group leader of the Central Systems Software group within the Systems Software Department 1988 thru 1994 but prefer to spend most of my time on software development/analysis like I do now. Before SDSC I was with the National Energy Research Supercomputer Center (at the time, the National Magnetic Fusion Energy Computer Center (NMFECC)) which had been at the Lawrence Livermore National Laboratory . Before that I was with Sperry Univac in the Minneapolis/Saint Paul area. I graduated (magna cum laude) with a BS degree in Computer Science from the University of Nebraska at Omaha in 1976.
Besides the art of software development and computer technology, I enjoy mountain bicycling, motorcycling, music (ambient, rock, metal, jazz, classical), reading science fiction/fact and technology, investing, travel, ocean swimming / bodysurfing / snorkling, nature/city walks, and time with my family. I'm married and have two children, grown men now, ages 28 and 25, and a dog and cat. See our SchroederFamily home page for more.
Also see my pictures and descriptions from my trip to Tanzania, including some humanitarian aid projects (Heifer International) (although this seems to be unavailable anymore).
The true measure of a life is how many miles one has ridden on a motorcycle; anything else is just plain silly.
