Do you currently use HPC supercomputing technologies?

Not really, although I am an expert in making things work fast on traditional CPUs using SIMD vectorization and multicore processing (mainly OpenMP). Turns out that the issues encountered in HPC optimization are usually very similar to the ones I am dealing with frequently.

Do you currently use GPGPU technologies?

Nope. I've extensive experience using OpenGL shaders, in some sense the precursor to OpenCL/CUDA. While I am interested in GPGPU, I usually find that the kind of problems I need to address don't map very well on GPGPU - yet. I expect that to change within the next few years.

What do you use HPC/GPU supercomputing for? Finance? Media? Scientific? Other?

Medical imaging.

How did you hear about this meetup group?

Via meetup - seeing which groups are close to Boulder.
