A Few Notes on Intel’s Knights Landing and MCDRAM Modes from SC15
 

When learning about new hardware, there are always different angles to look at it. For the most part, manufacturers talking to the media will focus on the hardware aspects of the new shiny thing, about what it can do at a high level then go into a low level silicon architecture detail (sometimes). Anything on the software side comes through talks about how to write for the new shiny thing – this is why Intel has conferences such as IDF (Intel Developer Forum) to help explain how to use it. Interestingly there can always be information about the true operating nature of the device in a software talk, as opposed to a hardware talk.

As such, I attended a tutorial session here at SuperComputing15 on the MCDRAM (Multi-Channel DRAM) used in Intel’s 2nd generation Xeon Phi, code named Knights Landing (KNL). Specifically the talk focused on the analysis methods and tools, and it went into greater depth as to how the implementation works.
