Heck what are those 8 cards? Recycled 295s......LOL. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Heck what are those 8 cards? Those are 8-45nm Knights Ferry cards, Knights Corner is supposed to be I guess 22nm in size, among other changes that is. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Before we know it Who? will be back, lol Last I heard, he was working on a v12 Jaguar........ I think he was using the handle v12extreme. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Before we know it Who? will be back, lol What kind of RAC does a V12 Jaguar have? |

Before we know it Who? will be back, lol I had bookmarked the site, but I've been though a couple of hard drive crashes since then and lost a lot. I'll come up with something...he was a PR man for Intel...should be googleable somewhere. I think his name was Francois. EDIT... Francois Piednoel "Freedom is just Chaos, with better lighting."

Over a year ago, I thought the article Compilers and More: Knights Ferry Versus Fermi was a well-balanced comparison. Some details have changed since, but it still looks like a good overview to me. Joe |

I honestly think this new processor would be a complete waste to use for SETI@Home or any other distributed computing application. It's not even useful as a server CPU. I don't see any uses for it, really. |

I don't see any uses for it, really. That would be a bit premature, Until someone makes an app, We'll never know, so I'll reserve judgement, as It's too early for saying that.

This looks like the Tyan system that I paid for that they took the money and ran. It was going to have 8 590s with 3 power supplies. About 25k worth. I would have loved to see what the RAC would have been on that. |

So from what I gather its basically 50 Pentium cpu's on a card. In order to make use of it you would have to either: 1. Run 50 wu at a time or 2. The app would need to multi-thread (and run however many instances / number of threads). The 2nd case would require the cpu apps to be become multi-threaded to take advantage of all those cores. There is no mention of it being OpenCL capable. One of the articles mentioned a clock speed of 1.8Ghz so they aren't that fast either, but then if you can use all 50 threads its not so important. How difficult would it be get Astropulse or Multibeam to multi-thread I wonder. |

In order to make use of it you would have to either: Since the standard CPUs are able to do OpenCL I would hope that these coprocessors would also be able to run it, but we may not know for a little while. Maybe the apps can be done in a way so the tasks will be sent to the card and it splits it up and it thinks best. Like we see with the GPUs now. Running 50 at a time might see interesting results in how saturated the PCIe bus gets.

1.8GHz is higher than I've seen. 1.2 more like it. These sort of speeds may be chosen to keep the heat down. How does the above system cope with heat dissipation if there's no space between the cards? Again I may have answered my own question here... |
