Ask HN: Where are the most jobs in parallel computing?

I have a non-traditional background, got a tenuous New media degree, self-taught in web development, with several years of work experience. Recently I moved into some freelance game development through some of my projects. I particularly enjoy coding pixel and vertex shaders. I find parallel computing intuitive for computer graphics.

I find this area of work very interesting and would like to follow it up possibly with a "leap of faith" into parallel computing work (keeping in mind my mostly self-taught background). Where should I begin looking for jobs in parallel computing? I don't know any people that are in these sorts of computing areas, so I'm trying to look for a good starting point on researching it.
