Seems pretty constructive to me. The o= riginal > poster has done research into the issue already. What research are you referring to? I must have missed that. There's no magic with GPUs. There are good reasons why few applications/inf= rastructure components use them. GPUs can be useful for very specific workl= oads but not necessarily general purpose app server. Btw there are also some workloads that could benefit from leveraging some o= f the x86 extensions around encryption, vector computation, ... So it boils down to being more specific re: where you think it could benefi= t and why. Andi =20 > The reason most things don't exist is that no one has a patch for it.
