C++ AMP Courses

May 26th, 2012

C++ Accelerated Massive Parallelism (C++ AMP) is a new open specification heterogeneous programming model, which builds on the established C++ language. Developed for heterogeneous platforms C++ AMP is designed to accelerate the execution of C++ code by taking advantage of the data-parallel hardware that is commonly present as a GPU. These courses are aimed at programmers who are looking to develop comprehensive skills in writing and optimizing applications using C++ AMP. Read the rest of this entry »

Accelerate OpenFOAM with SpeedIT 2.1

May 24th, 2012

SpeedIT provides a set of accelerated solvers for sparse linear systems of equations. The library supports C/C++ and Fortran, and it can be used with OpenFOAM to accelerate CFD simulations. SpeedIT 2.1 contains two new preconditioners:

• Algebraic Multigrid with Smoothed Aggregation (AMG)
• Approximate Inverse (AINV)

OpenFOAM simulations on the GPU can be up to 3.5x faster compared to CG and DIC/DILU preconditioners on the CPU and up to 1.6x faster if you run GAMG.

See the SpeedIT website and blog for more details.

NVIDIA Kepler GK110 Architecture White Paper

May 20th, 2012

NVIDIA Kepler GK110 Die Shot

This white paper describes the new Kepler  GK110 Architecture from NVIDIA.

Comprising 7.1 billion transistors, Kepler GK110 is not only the fastest, but also the most architecturally complex microprocessor ever built. Adding many new innovative features focused on compute performance, GK110 was designed to be a parallel processing powerhouse for Tesla® and the HPC market.

Kepler GK110 will provide over 1 TFlop of double precision throughput with greater than 80% DGEMM efficiency versus 60‐65% on the prior Fermi architecture.

In addition to greatly improved performance, the Kepler architecture offers a huge leap forward in power efficiency, delivering up to 3x the performance per watt of Fermi.

The paper describes features of the Kepler GK110 architecture, including

  • Dynamic Parallelism;
  • Hyper-Q;
  • Grid Management Unit;
  • NVIDIA GPUDirect™;
  • New SHFL instruction and atomic instruction enhancements;
  • New read-only data cache previously only accessible to texture;
  • Bindless Textures;
  • and much more.

SpeedIT 2.0 released

February 24th, 2012

SpeedIT 2.0 and the SpeedIT plugin to OpenFOAM have been released. New features include:

  • One of the fastest Sparse Matrix Vector Multiplication worldwide.
  • Faster Conjugate Gradient and BiConjugate Gradient solvers.
  • State-of-the-art CMRS format for storing sparse matrices. The format requires less memory than CRS or HYB (from CUSPARSE and CUSP).
  • Faster acceleration in OpenFOAM (Computational Fluid Dynamics).

Performance of SpMV in CUSPARSE, CUSP and SpeedIT

January 14th, 2012

The SpeedIt team recently compared and benchmarked the SpMV performance of CUSPARSE 4.0, CUSP 0.2.0 and SpeedIT 2.0 on 23 randomly chosen matrices from University Florida Matrix Collection. Comparisons were done on a Tesla C2050 in single and double precision. The full report is available at http://wp.me/p1ZihD-1.
