<HTML><BODY>I've cluster node (w/Linux, of course) based on Supermicro X9SCA system board and Xeon E3-1230v2 having LGA1155 socket. Now I want to buy GPU nVidia Kepler GK110 w/PCI-E 3.0 (CK20 Compute Board from PNY ?) and install it into my node. Intel Xeon E3-1230v2 and Supermicro X9SCA both support PCI-E 3.0.<br><br>But I've heard that GK110 (available today on the market) can't works in PCI-E v.3.0 mode w/Intel Equipment (only in PCI-E 2.0 mode). But GK104 etc, good for SP only, works w/PCI-E 3.0 normally. Moreover, for successfull work of GK110 w/Intel Xeon Platform I need:<br>a) to buy next version of Xeon processor which will have new socket (when it'll arrive to the market?)<br>and new PCI-E 3.0 support plus new system board for this processor (i.e. I need to modernize node hardware)<br>and b) to buy new GK110 version, which will have improved PCI-E 3.0 interface block (again, when it'll on the market?).<br><br>The reason, as I heard, is different realization of PCI-E 3.0 standard by nVidia and Intel in the corresponding currently available hardware. This is result of poor detalizations of PCI-E 3.0 standard, which should be defined more exactly.<br><br>Can somebody clarify this situation ?<br><br>Mikhail Kuzminsky<br>Computer Assistance to Chemical Research Center<br>Zelinsky Institute of Organic Chemistry RAS<br>Moscow <br><br><br><br><br></BODY></HTML>
