Feed The Cores – Memory Bandwidth Usage

“Memory bandwidth to the CPUs has always been important. There were typically CPU cores that would wait for the data (if not in cache) from main memory. However, with the advanced capabilities of the Intel Xeon Phi processor, there are new concepts to understand and take advantage of.”

Video: ddR – Distributed Data Structures in R

“A few weeks ago, we revealed ddR (Distributed Data-structures in R), an exciting new project started by R-Core, Hewlett Packard Enterprise, and others that provides a fresh new set of computational primitives for distributed and parallel computing in R. The package sets the seed for what may become a standardized and easy way to write parallel algorithms in R, regardless of the computational engine of choice.”

Memory Modes For Increased Performance on Intel Xeon Phi

The Intel Xeon Phi processor supports different types of memory, and can organize this into three types of memory mode. The new processor from Intel contains two type of memory, MCDRAM and DDR memory. These different memory subsystems are complimentary but can be used in different ways, depending on the application that is being executed. “By using these two types of memory in the same system gives flexibility to the overall system and will show an increase in performance for almost any application.”
