Probably not. The memory is "only" unified logically but not physically, i.e. accessing memory over the PCIe bus is still as costly as it was before. The feature just hides the complexity of doing so from the programmer. Which matters when writing new programs (and the automatism works well), but is of no benefit to a program already using careful manual memory management. Which I suppose GPU-grid is doing, because it's performing quite well. MrS Scanning for our furry friends since Jan 2002 |

Nope, because we don't need it. A very handy feature for newcomers to CUDA, to be sure, but not of much relevance to anyone who has an existing CUDA app. Matt |

I think the importance is that an application can use the GDDR from several GPU's; GDDR5 being faster than system RAM :) FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help |
