    Infiniband adapter question. mellinox vs other brands and cx2vs 3

    I have noticed a few 12$ ib cards from qlogic and cx2 rebaged as sun. is there any reason on the ib side to get a cx3 pro vs 3 reg or 2? I was not seeing any documentation related to ib performance only the v1 vs v2 roce. For now the only concern i have is ib related performance on these...

    I am looking to get a Intel True Scale Fabric Edge Switch 18-Port Switch I was trying to figure out if the brand of cable matters or not. Im hoping to fill a rack and need to find cables that would allow the cable management to work to pull the systems out. I suspect 15' cables would be...

    The Official NVIDIA GRID M40 Thread

    it would be a nice follow up article if you get a chance to map out things like which models in ati/nvidia support vm video as well as any other quarks that may be hiding. since I don't have an enterprise presence most of the contacts for ati/nvidia have not responded to any of my questions. It...

    The Official NVIDIA GRID M40 Thread

    that's good to hear It would have been supremely aggravating if it was 1 video card must be all cuda or all vm video. is that split on a per gpu basis or is it able to hand out both from a single gpu core? side note the M40 that is in the article appears to be a M10 per wikipedia M10...

    The Official NVIDIA GRID M40 Thread

    I would like to verify if my suspicion is correct. the article was talking about gpumodeswitch. I take it that you can't use the card to host vm displays and cuda at the same time. or is it possible to set 1 core to gpu mode and one to cuda? nvidia's information is painfully lacking on usage...
