Does Cuda have some ability to send raw data back to the cpu, and at what speeds?
ive been using directx and just writing shaders to process images and video but when i try to use directx the only way i have found to get any data out of the GPU was to copy the backbuffer before i sent it to the screen, and in that case it is just an image instead of raw processed datapoints.
basically im doing a lot of filtering and postprocessing on medical images and i need to use the gpu’s speed to run them but i would like to be able to save processed datapoints.
also i would like a faster way of getting the data out of the GPU because when i do grab the images, then i hit a max frame rate of about 8fps instead of the 100+fps without. ive looked a little at directshow but it seems like a real pain.
hopefully this hasnt been addressed a million times in posts already because i tried searching this forum but there’s some BS that wont let me.
