Concurrent Kernel Offloading

phi

“The combination of using a host cpu such as an Intel Xeon combined with a dedicated coprocessor such as the Intel Xeon Phi coprocessor has been shown in many cases to improve the performance of an application by significant amounts. When the datasets are large enough, it makes sense to offload as much of the workload as possible. But is this the case when the potential offload data sets are not as large?”

Why Hardware is Leaving Software Behind

pracedays1

In the first report from last week’s PRACEdays15 conference in Dublin, Tom Wilkie from Scientific Computing World considers why so much Exascale software will be open source and why engineers are not using parallel programs.

Load Balancing Using OpenMP 4.0

OpenMP

OpenMP 4.0 standard now allows for the offloading of portions of the application, in order to take more advantage of many-core accelerators such as the Intel Xeon Phi coprocessor.

New Whitepaper: Multi-Threading and Parallel Reduction for Xeon Phi

phi

Colfax Research has published a new whitepaper entitled: Multi-Threading and Parallel Reduction. As part 1 of a 3-part educational series, the paper authored by Ryo Asai and Andrey Vladimirov focuses on optimization of applications for the Intel Xeon processors and Intel Xeon Phi coprocessors.

Direct N-Body Simulation

In some domains, an N-Body simulation is key to solving for the movement and forces of a dynamic system of particles. At each time step, the force that one body exacts on each other, and then the velocity can be computed. The simulation can continue up to a desired number of time steps.

Today Cray announced that the SERC Research Center in Bangalore has installed India’s first Petaflop supercomputer. Called “SahasraT,” the 1.4 Petaflop Cray XC40 supercomputer is a hybrid system with Intel Xeon processors, Intel Xeon Phi coprocessors, and Nvidia GPUs.

Interview: Intel’s Alan Gara Discusses the 180 Petaflop Aurora Supercomputer

Alan Gara, Intel

In this interview, Intel’s Alan Gara describes the Aurora system, a 180 Petaflop supercomputer coming to Argonne. “The Aurora system is based on our Omni-Path second generation. This is an Intel interconnect that we’ve been developing for some time now, and we’re really excited about the capabilities that we expect and scalability that we expect it to bring to high performance computing.”
