Do you use open source OpenCL with GPU and parallel computing for HFT: Matlab Simulink DotNet FSharp FPGA or GPU

I just entered into a discussion with someone on this topic. Here is the latest from someone on my Meetup group:

Here are a couple quick sites that are along the lines I was thinking:

Our options are of course

1. FPGA via Smulink on Matlab thanks to Mr FPGA. Hey where are you by the way?

2. F# out of box for GPU and parallelism

3. Matlab prototyping and discovery via GPU Computing support

Which one would you use? LQ may build onto Open GL with Qt in C++ for Linux. What would you choose?
