Taking place this week in Frankfurt, Germany is the 2015 International Supercomputing Conference. One of the two major supercomputing conferences of the year, ISC tends to be the venue of choice for major high performance computing announcements for the second half of the year and is where the summer Top 500 supercomputer list is unveiled.

In any case, Intel sends word over that they are at ISC 2015 showing off the “Knights Landing” Xeon Phi, which is ramping up for commercial deployment later this year. Intel unveiled a number of details about Knights Landing at last year’s ISC, where it was announced that the second-generation Xeon Phi would be based on Intel’s Silvermont cores (replacing the P54C cores in Knights Corner) and built on Intel’s 14nm process. Furthermore Knights Landing would also include up to 16GB of on-chip Multi-Channel DRAM (MCDRAM), an ultra-wide stacked memory standard based around Hybrid Memory Cube.

Having already revealed the major architecture details in the last year, at this year’s show Intel is confirming that Knights Landing remains on schedule for its commercial launch later this year. This interestingly enough will make Knights Landing the second processor to ship this year with an ultra-wide stacked memory technology, after AMD’s Fiji GPU, indicating how quickly the technology is being adopted by processor manufacturers. More importantly for Intel of course, this will be the first such product to be targeted specifically at HPC applications.

Meanwhile after having previously announced that the design would include up to 72 cores - but not committing at the time to shipping a full 72 core part due to potential yield issues - Intel is now confirming that one or more 72 core SKUs will be available. This indicates that Knights Landing is yielding well enough to ship fully enabled, something the current Knights Corner never achieved (only shipping with up to 61 of 62 cores enabled). Notably this also narrows down the expected clockspeeds for the top Knights Landing SKU; with 72 cores capable of processing 32 FP64 FLOPs/core (thanks to 2 AVX-512 vector units per core), Intel needs to hit 1.3GHz to reach their 3 TFLOPs projection.

Moving on, Knights Landing’s partner interconnect technology, Omni-Path, is also ramping up for commercial deployment. After going through a few naming variants, Intel has settled on the Omni-Path Fabric 100 series, to distinguish it from planned future iterations of the technology. We won’t spend too much on this, but it goes without saying that Intel is looking to move to a vertically integrated ecosystem and capture the slice of HPC revenue currently spent on networking with Infiniband and other solutions.

Finally, in order to develop that vertically integrated ecosystem, Intel is announcing that they have teamed up with HP to build servers around Intel’s suite of HPC technologies (or as Intel calls it, their Scalable System Framework). HP will be releasing a series of systems under the company’s Apollo brand of HPC servers that will integrate Knights Landing, Omni-Path 100, and Intel’s software stack. For Intel the Apollo HPC systems serve two purposes: to demonstrate the capabilities of their ecosystem and the value of their first-generation networking fabric, and of course to get complete systems on the market and into the hands of HPC customers.

    Source? The Larrabeen microarch was to be used for GPU designs, but I don't remember seeing anything about a discrete GPU version of Phi. Reply

    Why wouldn't Intel sell a product to a market if they had a viable product? ??? Reply

    They would.

    So it probably wasn't viable. Intel is pretty spectacular at predicting the success of a given product. They just don't fuck up.

    Exactly. They only recently managed to catch up with AMD in GPU performance for their on-chip engines, and that's only by having their 128MB eDRAM cache in the Iris Pro designs. Reply

    And AMD put 4g of HBM memory on their FURY X and still lose to their chosen opponent.

    Intel has made good ground, and is catching up quick.

    It doesn't matter how they get it done, as long as they get it done. You can do better, then do it yourself and be rich and famous.

    They've been on a roll recently; but the p4 architecture and the Itanic are proof that Intel can screw the pooch on released hardware as badly as anyone else. Reply

    Haha, that was a difficult time in my household... Reply

    As they say, good enough is the enemy of great - Intel doesn't see the need for great graphics because theirs is already good enough. Reply

    I seem to remember owning an Intel GPU when I was younger... much younger... like late 90's...

    I also remembering being much happier when I upgraded to a VOODOO and was finally able to play Final Fantasy 7. :D
