The latest incarnation of the Intel Xeon Phi product line, codename Knights Landing (KNL), is becoming more broadly available. As such, there is a lot of interest in how it performs, particularly when compared to other contenders in the high performance computing landscape. I have posted STREAM benchmark results for KNL earlier in my blog, which outlined the potential benefit of the high bandwidth memory (MCDRAM) of KNL. Let us have a look at a more complicated operation, which is neither lim...| Karl Rupp
The Knights Landing (KNL) update of Intel's Xeon Phi product line is now available. For the applications I'm primarily interested in, namely the numerical solution of partial differential equation, the typical bottleneck is memory bandwidth. To assess memory bandwidth, the STREAM benchmark is the de-facto standard, so let us have a look at how KNL compares to the previous Xeon Phi generation (Knights Corner, KNC) as well as to the Xeon product line.| Karl Rupp

My popular blog post on CPU, GPU and MIC Hardware Characteristics over Time has just received a major update, taking INTEL's Knights Landing and NVIDIA's Pascal architecture into account. Moreover, I added a comparison of FLOPs per clock cycle, which I want to discuss in slightly greater depth in this blog post.| Karl Rupp
