The linear algebra library routines we will need for a full GPU solution
are there, i.e., GPU accelerated LAPACK routines, but not an end-to-end
curve fitting solution yet.
As part of that work on the poster last year, I was able to do GPU
accelerated function evaluation and get a decent speed up (about 6x) for
fitting. Depending on your fitting function, this might be a good solution.

I just wanted to thank you and TechX for making a free version of GPULib available. Installing the latest version was extremely easy on my MacBook Pro (IDL 8.2.2), and it worked flawlessly out of the box. I particularly like that GPULib offers a layered implementation, providing access to very IDL-like syntax at the highest level and very high-performance functionality for people who are willing to look under the hood.
All the best,
David
