Interesting, I hadn't realized it was such a specific design. It makes it even more interesting for the farm. https://en.wikipedia.org/wiki/Project_Denver > > 32 GB RAM, and a big GPU. > > Don't get me wrong, 512 CUDA cores *is* impressive in the context of a > single-board computer, but one can't really refer to it as "big." > Thousands of cores is big, 512 is really entry level:-) In essence one > can divide the amount of CUDA cores by 32 in order to get a more > down-to-earth number.

Yes, you're right, but it's still rather impressive given the form factor and price. > Most common way to use Nvidia GPUs for general-purpose computing is > CUDA, with OpenCL being another option.

Otherwise, we would need Nvidia proprietary drivers & CUDA, or just don't use the GPU at all. Thanks, Baptiste
