Gauss-Makrov on GPU #6

Closed phaim closed 4 months ago

phaim commented 4 months ago

The the loop in the general gm-process introduced in this commit leads to significant performance degradation of the correlated field on the GPU. This seems to be caused by this loop. A potential fix could be to implement a specialized function where it is changed to a cumsum and use that function in the correlated field.

@ph-frank Can you take care of this?

Fixed. See Merge request ift/nifty!927
