The PGI Accelerator Programming Model on NVIDIA GPUs—Part 1

GPUs have a very high compute capacity, and recent designs have made them more programmable and useful for tasks other than just graphics. This article is the first in a series on PGI's accelerator-enabled compilers. Part 1 takes an in-depth look at PGI's Accelerator Programming Model.

Tool Tips: Accessing Compiler Performance Advice

Traditional methods of performance tuning can only get you so far. Using PGI compiler feedback with the PGPROF profiler can ease the task of improving application performance. Part 1 in a series.

Cross Platform: Developing Local MPI Programs

Systems with PGI Workstation installed can build, run, debug and profile MPI applications with up to eight processes running locally. This article describes how to set up and go about developing MPI applications locally placing particular emphasis on differences between Linux, Mac OS X and Windows.

An Accelerator Programming Model for Multicore

This article explores using a version of the PGI Accelerator Programming Model on a multicore target. The authors attempt to answer two questions: whether the model can target a multicore processor, and whether doing so is a good idea.

Upcoming Events

ISC'09, Hamburg, 23-26 June, booth A2.3. PGI will also be hosting "A High Level GPU/Accelerator Programming Model" BoF at 12:20 PM Friday in Hall C2.2.

Michael Wolfe will be presenting a one hour webinar titled "PGI x64+GPU Fortran & C99 Compilers" on the PGI Accelerator programming model on June 16. Hosted by IEEE Spectrum. Register to attend.
