Default

GPU = Quadro RTX 8000
LA = 3331s


Now that we can run msieve on a GPU we have no reason to ever run it on a CPU again. This result is 3.8× faster (!) than the best CPU time we ever recorded!



Thanks to frmky for the instructions to get it working. We had to do a few extra steps but if we were able to figure it out anybody can!
