Hi all, When would I ever use GPU computing for a finite element simulation where the limiting factor of performance is the memory bandwidth bound? Say I want to run problems similar to SNES ex12 and 62. I understand that there is an additional bandwidth associated with offloading data from the CPU to GPU but is there more to it? I recall reading through some email threads about GPU's potentially giving you a speed up of 3x that on a CPU but the gain in performance may not be worth the increase in time moving data around.
Thanks, Justin
