Who would have thought that a mere two hundred lines of code provide so many capabilities! The chapter authors (Iosif Meyerov, Alexander Sysoyev, Nikita Astafiev, and Ilya Burylov) apply their optimization expertise for Intel Xeon and Intel Xeon Phi to calculate the fair prices of a set of European options. They chose this the Black-Scholes calculation for the following … [Read more...]
Efficient Nested Parallelism On Large Scale Systems
Choosing right threading library is critical for application performance, as different threading libraries provide significantly different performance behavior, especially when dealing with the complex computer systems as Intel Xeon Phi coprocessor and NUMA Intel Xeon processor machines. Unfortunately, choosing the right threading library is not enough, addition application … [Read more...]

NWChem Quantum Chemistry Simulations at Scale
This chapter describes the performance of NWChem's CCSD(T) method running on a large-scale hybrid cluster of 460 dual-socket Xeon E5-2600 series nodes each of which is equipped with two Intel Xeon Phi 5110P coprocessor cards (a total of 62.5k hybrid cores). The chapter authors describe how, without any low-level programming, offload transfers and compute kernels have been … [Read more...]

The MSI WS60 As A Mobile Workstation Teaching Tool
After nearly a month of utilizing the MSI WS60 Mobile Workstation I have to admit I am spoiled by the speed and balance of this system. The clear IPS display is a pleasure to use when mobile and I love the color images on my Dell U3011 screen, courtesy of the NVIDIA K2100M GPU plus the Optimus technology preserves battery life. Speed The following animated gif (repeated 10 … [Read more...]
Native File Systems on Intel Xeon Phi
A teraflop/s computational capability is useless without data. The Intel Xeon Phi family supports a number of file systems including Lustre, NFS, Fraunhofer BeeGFS® (formerly FHGFS), and the Panasas® PanFS® file system. The chapter author, Michael Hebenstreit, also discusses the importance of a correct network setup. He notes in his chapter summary (courtesy Morgan … [Read more...]
Integrating Intel Xeon Phi Coprocessors into a Cluster Environment
The chapter authors build on the standard Intel MPSS documentation that provides the information required for workstation installs, but does not provide techniques needed for successful deployment in a cluster environment. Based on multiple authors' many years of experience managing HPC clusters and specific experience with the Intel Xeon Phi coprocessor family since the … [Read more...]
