Last two commits go to #3365, a little bit of dyslexia :)

This will probably not be implemented in Mantid unless we get a cluster with GPUs at some point. It might make sense to look at OpenACC , which is another possible technology for writing GPU code. It looks to be very close to OpenMP style pragmas, which would be nice. Later versions might even have interchangeable pragmas...
