Has all of the GPU code also been updated in the new FS6.0 version or the code is still from the old 5.x but can be compiled with new cuda toolkits?
I made a small tweak for GCAMorph (primarily ca_register) which might have made it in to v6; I'm not aware of any other changes. However, being compiled with a new compiler for the new architectures should give a small speed boost.
Thanks for the info.
However if the cpu code in FS6 is changed a lot, but the cuda code not, then the results would be different even if we get speed boost. Then how would we take the different results?
I don't know if there have been changes in the relevant portions of the CPU code. And unfortunately, there aren't any automated comparisons. If there have, then there will obviously be larger deviations between the CPU and GPU streams (they will never be identical anyway).
