For HFT: Nvidia GPU CUDA super computing capability thanks to Tesla Compute Cluster with specific Windows HPC support
It looks like you can extend into buildnig super computing capability with Tesla Compute Cluster. It seems more geared to towards with Windows with HPC support but there is pribably painful Linux support. This enables you to chain multiple Tesla boards together so that is a big neat.
