I was thinking about SLI & XFire support? Why, because not only would that decrease the time that it take to crunch a WU on already powerful GPU's, but also will allow HTPC's & other PC's that use two or more less powerful GPU's.

Last modified: 5 Feb 2010, 11:51:34 UTC Can't yet, or won't ever? If SLI slips the graphic up in 2,3, or 4 parts on one screen. Can't CUDA work in such a way or maybe GPUGRIDE.net could WU split up into sets? Is there not a way to make better use of 2 GPU's or more working on the same task? The PCI-E lanes have a maximum speed, if 32 lanes were used instead of 16? Or is this just not possible? ID: 15016 · Rating: 0 · rate: / Reply Quote

I don't know for sure, but probably not possible. gdf ID: 15051 · Rating: 0 · rate: / Reply Quote
