Regarding the proprietary-ness of CUDA, I would argue that being
proprietary also means that it probably better targets the NV GPU
architecture, and a more general, portable solution, like OpenCL (which
seems to be closer than expected, by the way) will possibly mean a
somewhat less optimal use of the GPU. M
Guys, I'm going to be controversial here.
The market may SAY otherwise, but the market does not give a rat's
behind about proprietariness.
Absolutely true. The market cares about price and price performance.
Tell a scientist that her N-body dynamics astrophysics model will run
500 times faster on a certain GPU and
she'll get more papers published and an invite to a conference in Hawaii
next year and you'll see those
grant dollars being spent.
Yup.
Tell and engineer that his Nastran model or his CFD simulation will
finish whilst he goes off to lunch/coffee and he'll
bite your hand off.
:)
The idea is for users, that increasing throughput is most important.
Minimizing the wallclock time at the most reasonable price, or getting
the least price and a reasonable wall clock time.
It all comes down to codes - when the ISV codes use these things, you'll
see the uptake.
Yup. Thats it. Not controversial, but quite true. Without the ISVs,
there will be no clear winner. With the ISVs, you will see one emerge.
My take is that one is emerging.
