​Whoa, you're leaping way too fast here. GPU are better at number crunching, but only at that, and litteraly at number crunching. Branching, working with the rest of the hardware, interrupts, and even some kind of float or integer operation are not exactly their shining part. I agree that moving the *relevant* operations to GPU-based hardware can (and actually do) provide a very large boost, but the kind of operation that benefit from them is really limited. There is a reason we still have those general-purpose CPU around you know. Talking about windows or linux systems that are GPU based is a bit of a stretch. Even for LO Calc, formulas that are more complicated than "add x and y", for example using lookup functions, statistical functions and other funny stuff would probably not run better on GPU. One of the key point of the GPU (or GPGPU, general purpose GPU) performance boost is that you can handle *arithmetic operations* that are *massively* parallel, not that you have a lot of raw computing power. -- Cley Faye http://cleyfaye.net -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
