Would the NUMA issue apply to a single processor system? Yes, it's not limited to the number of processor packages, but it depends on the number of CPU cores/threads. If there are more than 64 CPU threads, they will need to be divided into multiple CPU Groups (due to several factors including affinity mask, which is a 64-bit wide register). And if there are multiple groups, BOINC might have issues assigning proper group affinity to child processes (WUs).  [Edit 1 times, last edit by Mumak at Dec 3, 2015 3:55:57 PM] |

I am about to get a Knights Landing Xeon Phi from Intel. I would like to be able to help out in testing, if anyone is interested. I don't know anything about programming, I just crunch. Which one would you like to get ? I don't think it makes (crunching) sense to get the current x100 series (Knights Corner) and the self-boot Knights Landing wasn't released yet. I'd be certainly interested in testing the later one... |

Next iterations of the Phi are Knights Mill at 14nm and Knights Hill at 10nm. Not a lot of info yet but some here - http://www.theregister.co.uk/2016/08/17/intel_xeon_phi_knights_mill/

Has anybody actually tried this and got it working? Only way this could work with WCG science is a "virtualization", which could take a lot of RAM also...but no, haven't tried it! too expensive for a TOY!  |

As soon as such a board (incl. CPU) will be affordable and will operate under Linux and support boinc/WCG, it could become a real and strong temptation !!!
----------------------------------------My concern is about the necessary network bandwidth for down- and upload purpose. |
