Keith Stewart has a job that can be hard to describe. "I'm the senior high-performance computing (HPC) engineer for ASCTech," says Stewart. "This means that I help researchers around college make science happen, and generally it's something that requires resources that aren't normal for computing," he says.
What kind of computing resources aren't normal?
"I work with a researcher whose computations take 21 days on a single computer. That computer has three terabytes of memory: not three terabytes of disk space, but three terabytes of memory, so it's a very expensive box with a lot of computation power because they're assembling a genome. That's the kind of need we see frequently." This growing need for high performance computing led to the creation of the Unity cluster, a project that leverages computing resources throughout the university. "Unity is our next big step in supporting HPC computing," says Stewart. "I'm really looking forward to how it will improve research here."
Stewart's interest in computers follows from his time at Ohio State. "I have a Bachelor of Science in economics from Ohio State, but my career resulted from my becoming involved with the Ohio Supercomputer Center. Once I saw what you could do with computers on a much larger scale, I really wanted to work in high-performance computing!" says Stewart.
If you need someone to help with your technology, request help from ASCTech and maybe you'll work with Keith Stewart.
