FFT using multiple GPUs with reikna

[zlff...@gmail.com]

I have 2 tesla gpu.

I want to calculate fft using 2 gpus with reikna.

Is it possible?

If it is impossible, does scikit-cuda module supports multiple gpus for fft?

No, unfortunately, currently there is no support in Reikna for that. In fact, there is not any specific support for multi-GPU setups at all (not that it is not possible, I'm just not sure how to handle it better).

As for scikits-cuda, there are some multi-GPU functions for linear algebra, but not for FFT.
