What is necessary to make this card work with WCG?
----------------------------------------Is a compiler needed? Will WCG "see" and use the card automatically? Any and all info appreciated!  |

Hello Movieman,
https://en.wikipedia.org/wiki/Intel_MIC says that it requires OpenCL (or other drivers), special math libraries and special Intel compilers. So the application program has to be written for parallelized algorithms. Sounds like it is possible to learn how to write the code if you are familiar with OpenCL and have a parallel algorithm. So, similar to writing and compiling for GPUs but easier to learn if you already know C++ or Fortran for the x86. WCG does not have any projects running or in the pipeline for GPUs or Intel PHIs.

Lawrence Thank you Lawrence. Not what I wanted to hear but thats life. As to me knowing C++ or Fortran the last time I played with any language was BASIC and I had enough problems with that!  |

Beren doing a little research the past few days and it seems if you want to use this card with windows then it requires some coding work BUT if you use a linux OS it only requires some pretty easy commands.
----------------------------------------Doing a call with a guy tomorrow night that worked on this in the development state and I think I'm going to be doing my first Linux install.. maybe old dogs can learn new tricks!  |

So if Xeon Phi cards require OpenCL and WCG has none of these projects at the moment, what is the way to get the most cores running a WCG project at once? Is it getting motherboards that support 2 CPUs and have each CPU running 8, 12, or 16 cores?

what is the way to get the most cores running a WCG project at once? The answer to your question depends only on how much money you are willing to spend. If you have the resources, you could invest in a high end blade server, for instance, one of these: http://www.ebay.com/itm/DELL-POWEREDGE-M1000E...ADE-SERVERS-/380458161699. Fully loaded that would get you 128 cores. Or perhaps one of these: http://www-03.ibm.com/systems/x/hardware/enterprise/x3950x6/index.html If money is no object you can rent time in the cloud and have as many cores as you want. Cheers

The current Xeon Phi (Knights Corner) is a Coprocessor. So you can't run 'usual' apps there, it requires special compilation, etc. Moreover, I think there are only some systems validated for these cards and they are quite difficult to get.
----------------------------------------I'd suggest to wait 'a bit' for the next generation called Knights Landing. This little beast will also work as a many-core main CPU ! And it will have lots of threads ;) More than anything currently available, more than Skylake-EP ;) This is what I can currently share with public: - “Knights Landing” code name for the 2nd generation Intel® Xeon Phi™ product - Based on Intel’s 14 nanometer manufacturing process - Standalone bootable processor (running the host OS) and a PCIe coprocessor (PCIe end-point device) - Integrated on-package high-bandwidth memory - Flexible memory modes for the on package memory include: cache and flat - Support for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) - 60+ cores, 3+ TeraFLOPS of double-precision peak performance per single socket node - Multiple hardware threads per core with improved single-thread performance over the current generation Intel® Xeon Phi™ coprocessor Running such a machine will bring the new diamond badges much closer ;)  [Edit 1 times, last edit by Mumak at Jun 8, 2014 8:20:20 PM] |
