Why Modernize Code?

Intel_HPC_CodeM_IDZweb_HERO_375x420

In order to speed up applications, a developer must learn to take advantage of the multiple threads, cores and sockets found on a single server or on a cluster. Just hoping for a faster CPU anymore won’t cut it.

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

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.

Fortran Still Going Strong

Fortran still going strong. NERSC estimates that over half the hours on their systems are used by Fortran codes. This is quite amazing, given that Fortran first appeared about 60 years ago.

NAG Library adds New Algorithms for Application Developers

Today the Numerical Algorithms Group (NAG) released their latest NAG Library including over 80 new mathematical and statistical algorithms.

Interview: AutoTune – Automated Optimization and Tuning

Michael Gerndt, Technische Universität München

The main goal of AutoTune is the automatic optimization of applications in the area of HPC, targeting both performance optimization and energy efficiency. In this interview, Michael Gerndt from the Technische Universitaet Muenchen tells us more about the project.

Fault Trees

FaultTree

As datasets and simulations continue to increase in size and complexity, interactivity with the data should be maintained. It is important to understand how SIMD parallelism can be used when evaluating large fault tree expressions on a large volume of input.

Video: Software Tools for Intel Xeon Phi Co-processors

vadim karpusenko

In this video, Vadim Karpusenko from Colfax International describes the software tools for developing applications for Intel Xeon Phi coprocessors. The session begins with software that is necessary to boot coprocessors and to run pre-compiled executables on them.

Optimizing Navier-Stokes Equations

Solving Navier-Sokes equations are popular because they describe the physics of in a number of areas of interest to scientists and engineers. By solving these equations, the flow velocity can be calculated, and then other quantities of interest, such as pressure or temperature may be determined.

HPC and Software Modernization

Dr. Herbert Cornelius, Intel

“As we see Moore’s Law alive and well, more and more parallelism is introduced into all computing platforms and on all levels of integration and programming to achieve higher performance and energy efficiency. We will discuss Multi- and Many-Core solutions for highly parallel workloads with general purpose and energy efficient technologies. We will also touch on the challenges and opportunities for parallel programming models, methodologies and software tools to achieve highly efficient and highly productive parallel applications. At the end we will take a brief look towards Exascale computing.”
