Design
Some drawings and pictures and such need to go up here.
GPFS Plunger
When I worked at Argonne National Laboratory, we used GPFS rather extensively. My relationship with the filesystem was pretty bipolar: when it worked, I
really liked it. And when it had problems, I
really hated it. Eventually we concluded that sometimes it just needed a plunger to clean out the tubes, so I
drew one up to help the cause.
Cluster Fish
When I was a grad student, I wrote a cluster health visualization tool modeled after a
fishtank. The project has since been passed from hand to hand among other grad students at UNL, but I've always been fond of the little fish that I created. In early 2011, I finally decided to
recreate him with Blender.
Science per hour
For whatever reason, high performance computing managers like to refer to "science" as a concrete thing: "We're getting a lot of science done on that cluster." At some point I decided we needed a little meter to show just how much science we were getting done at a given moment.
Several kilosciences per hour, it turns out.
