Performance, Power and Price: Get the Most Out of Xeon Phi

What is the relationship between price-performance and performance vs. power consumption? This Colfax International white paper written by Andrey Vladimirov takes a deep dive into parallel scalability, power and cost factors both with and without Xeon Phi coprocessors. The results are mapped for clusters vs. single devices, with a performance …

Calculating Pi with Monte Carlo and MKL

The Math Kernel library provides a great way for calculating huge arrays of random numbers. Creating a Monte Carlo simulation is then easy once you have these random numbers. Jeff Cogswell shows how you can use both MKL and a Monte Carlo algorithm to estimate pi, thus learning the mechanics …

Tackling Concurrent Kernel Offloading in Xeon Phi

The Xeon Phi coprocessor includes 61 cores, allowing for great scalability in programs. But some programs don’t scale well, requiring different approaches to maximizing performance. In this blog, Jeff Cogswell explores a chapter from the book “High Performance Parallelism Pearls,” which covers this topic in detail. Here at Go Parallel, …

Tapping into Random Number Generators in MKL

The Math Kernel Library (MKL) includes a whole set of random number generators that are parallel-friendly and thread-safe. These generators can quickly fill entire arrays with random numbers, even when the arrays contain millions of elements, all with a single function call. Jeff Cogswell puts them to use and looks …

Scale Performance from Multicore to Many-Core

Implementing a parallel algorithm can get frustrating at times. Developers can thread an application, but see little performance gain. Or they can hit a scalability ceiling where performance gains level off as more cores are added. A newly updated tool, the Advisor XE 2015, can help solve those issues by …
