Accelerate Your Scientific Code with OpenACC
The Open Standard for GPU Accelerator Directives

 
 

Thousands of cores working for you.
Based on the OpenACC standard, GPU directives are the easy, proven way to accelerate your scientific or industrial code. With GPU directives, you can accelerate your code by simply inserting compiler hints into your code and the compiler will automatically map compute-intensive portions of your code to the GPU. Here's an example of how easy a single directive hint can accelerate the calculation of pi. With GPU directives, you can get started and see results in the same afternoon.

PI Code

By starting with a free, 30-day trial of PGI directives today, you are working on the technology that is the foundation of the OpenACC directives standard. OpenACC is:

  • Easy: simply insert hints in your codebase
  • Open: run the single codebase on either the CPU or GPU
  • Powerful: tap into the power of GPUs within hours

Coming in Q1 2012, OpenACC is supported by industry parallel computing tool leaders: Cray, CAPS, and The Portland Group (PGI).

"I have written micromagnetic codes (written in Fortran 90) to study the properties of two and three dimensional magnetic systems. The directives approach enabled me to port my existing code with ease to perform my computations on the GPU which resulted in a significant speedup (more than 20 times) of the computation."

"The PGI compiler is now showing us just how powerful it is. On the software we are writing, it's at least 60 times faster on the NVIDIA card. We are very pleased and excited about the future uses. It's like owning a personal supercomputer." Learn more...

Follow these 2 simple steps to help you get started with GPU directives.

1. Read the short Directives Tips for a Fortran Program or Directives Tips for a C Program.
2. Watch the Introduction Video to PGI Accelerator
Colgrove presentation
Introduction to Directives

You'll need an NVIDIA® CUDA-capable GPU and a Fortran or C based application to get started. Don't have a GPU? We recommend an NVIDIA Tesla C2075 GPU.
