The second problem is finding a motherboard with suitable slots. We settled on taking an old PC (that had a fault on its motherboard) and reusing the case, disk etc. We used an Earthwatts EA-750 supply. The Tesla C870 needs two six-wire power connections &#8211; like an HDD. See picture.<\/p>\n<p>The board has an NVidia graphics chip set. This has some interesting implications&#8230;<\/p>\n<p>The operating system is <a href=\"http:\/\/www.ubuntu.com\/\" target=\"_blank\">Ubuntu<\/a> 9.10, 64 bit. We have another Tesla card in a Windows system. The disadvantage of Ubuntu over other Linux distros is that there is little choice about versions of associated packages. I wanted gcc 4.4 because that includes <a href=\"http:\/\/openmp.org\/wp\/\" target=\"_self\">OpenMP <\/a>3.0. Ubuntu 9.04 has gcc 4.3, which would have required a separate gcc build. The downside of this choice is that the NVidia CUDA examples don&#8217;t compile with gcc 4.4.<\/p>\n<p>The OpenCL drivers and SDK (Software Development Kit) were downloaded from NVidia&#8217;s <a href=\"http:\/\/www.nvidia.com\/object\/cuda_opencl.html\" target=\"_blank\">site<\/a>. (Once you have registered, bookmark the page to avoid re-registering!)<\/p>\n<p>To install the drivers, the X Window system needs to be off. So this requires a &#8220;safe&#8221; boot from the console.<\/p>\n<p>I copied the SDK to \/usr\/local\/NVIDIA_GPU_Computing_SDK<\/p>\n<p>I put <a href=\"https:\/\/help.ubuntu.com\/community\/FreeNX\" target=\"_blank\">freenx <\/a>on the system. It is possible to run OpenCL and CUDA examples remotely with freenx and with vnc (and with ssh login), but obviously(?) the graphics acceleration isn&#8217;t there.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The major problem with the Tesla cards is power.
