Libra SDK is a sophisticated runtime including API, sample programs and documentation for massively accelerating software computations. This introduction tutorial provides an overview and usage examples of the powerful Libra API & math libraries executing on x86/x64, OpenCL, OpenGL and CUDA technology. Libra API enables generic and portable CPU/GPU computing within software development without the need to create multiple, specific and optimized code paths to support x86, OpenCL, OpenGL or CUDA devices.

KOAP, pronounced “cope,” is a tool for developing OpenCL applications. It’s purpose is to allow the programmer to aggregate and simplify calls to the OpenCL API. KOAP accepts as input a file containing (or including) both the OpenCL program and the host C program. KOAP understands several directives, each of which is prefixed with a $ character. When KOAP is run, these directives are replaced with the requisite OpenCL API calls. Programs preprocessed by KOAP can run on any target supported by OpenCL, including both NVIDIA and AMD GPUs.

KOAP is now freely available as a source code tar file from http://aggregate.org/KOAP/.

Jacket 1.8 and LibJacket 1.1 have been released by Accelereyes, enabling GPU support for MATLAB and easier CUDA development with C/C++/Fortran and Python.  New features include:

• Expanded support for the Signal Processing, Image Processing, and Statistics Libraries included with both Jacket and LibJacket
• Faster linear algebra for special systems (e.g. symmetric, positive definite, triangular, etc.)
• Enhanced visualizations
• New and updated examples: FDTD, Mandelbrot fractals, maximum-likelihood neural segmentation, MDS for genomics
• Built with CUDA 4.0 for peak performance

OpenCL Studio combines OpenCL and OpenGL into a single integrated development environment for high performance computing. The feature rich editor, interactive scripting language and extensible plug-in architecture support the rapid development of complex parallel algorithms and accompanying visualization. The first production version of OpenCL Studio including instructional videos and demo applications are available at www.opencldev.com.

SpeedGo Computing recently announced their development of CUDA bindings for Ruby. Currently, only part of the CUDA Driver API is included. More components such as the CUDA Runtime API will be added to make it as complete as possible. More details as well as sample code can be found in this blog post.

OpenCurrent version 1.1.0 has been released. OpenCurrent is a library for solving certains types of PDEs over 3D cartesian grids. It supports single and double precision, and includes solvers for Poisson equations, diffusion, and incompressible Navier-Stokes.

New features:

• Multi-GPU communication library
• Multi-GPU versions of Multigrid solver, Incompressible Navier-Stokes solver, and more
• NetCDF support now optional
• Support for Fermi/CUDA 3.0
• Numerous bug fixes and enhancements

CAPS has recently added an OpenCL code generator to the just released 2.3 version of its HMPP directive-based hybrid compiler. Also, the CUDA back-end generator has been enhanced with Fermi capabilities and this new release brings support for more native compilers with Intel ifort/icc, GNU gcc/gfortran and PGI pgcc/pgfort compilers, enabling developers to freely use their favorite compiler with HMPP 2.3.

Based on GPU programming and tuning directives, HMPP offers an incremental programming model that allows developers with different levels of expertise to fully exploit GPU hardware accelerators in their legacy code. Read the rest of this entry »

Jaideep Singh and Ipseeta Aruni present a GPGPU wrapper for the R statistical computing environment at the R user conference 2010. Their approach is to overload datatypes using R’s simplified wrapper and the SWIG Interface Generator functionality. A full page summary of the approach is available at the conference web site (PDF link).

Geist Software Labs has released the first version of OpenCL Studio for beta testing. OpenCL Studio combines OpenCL and OpenGL into a single integrated development environment that allows you to visualize OpenCL computation using powerful 3D rendering techniques. The editor hides much of the complexity of the underlying APIs while still providing flexibility via the Lua scripting language. Integrated source code editors and debugging capabilities for OpenCL, GLSL, and Lua, as well as a toolbox of 2D user interface widgets provide a framework for a wide range of parallel programming solutions.
