I agree with you, it will allow to run some parts of llvm compiled apps to run in gpu, perhaps even parts of FreeBSD. A fullpower driver is the last piece of the puzzle. Don't know who has to do the first step, FreeBSD who changes the kernel to allow easier port of the linux drivers or nVidia/AMD begin the port and tell us what must be changed to make it. >I still have hope that the important part HPC will become again an >option using FreeBSD as it was 10 years ago. The part of my hpc app in FreeBSD is the scheduler and data collector. The "real" hpc number crunching part runs on Linux with cuda code. >Regards, >Oliver L
