Wind simulation from Autodesk

Autodesk are happy to announce another technology preview on Autodesk Labs.

Project Falcon for Alias software on Autodesk Labs

Project Falcon for Alias software is a wind tunnel simulator that allows designers to interactively investigate the aerodynamic performance of their designs. Flow and wind pressure results update almost in real-time in response to changes in wind-direction and speed.

Spark: Modular, Composable Shaders for Graphics Hardware

Spark: Modular, Composable Shaders for Graphics Hardware

By Tim Foley (Intel Corporation and Stanford University), Pat Hanrahan (Stanford University)

In creating complex real-time shaders, programmers should be able to decompose code into independent, localized modules of their choosing. Current real-time shading languages, however, enforce a fixed decomposition into per-pipeline-stage procedures. Program concerns at other scales - including those that cross-cut multiple pipeline stages - cannot be expressed as reusable modules.

We present a shading language, Spark, and its implementation for modern graphics hardware that improves support for separation of concerns into modules. A Spark shader class can encapsulate code that maps to more than one pipeline stage, and can be extended and composed using object-oriented inheritance. In our tests, shaders written in Spark achieve performance within 2% of HLSL.

AMD APP KernelAnalyzer 1.9 (OpenCL)

"AMD has published an update of its tool for OpenCL developers. AMD’s APP KernelAnalyzer is a tool to compile, analyze and disassemble OpenCL, Brook+ or IL (Intermediate Language) kernels for Radeon GPUs. APP SDK v2.5 or greater is required for OpenCL support and ATI Stream 1.4 for Brook+.

AMD APP KernelAnalyzer main features
Compile, analyze and disassemble the OpenCL kernel for multiple Catalyst driver versions and GPU device targets.
View any kernel compilation errors and warnings generated by the OpenCL runtime.
View the AMD Intermediate Language (IL) code generated by the OpenCL run-time.
View the ISA code generated by the AMD Shader Compiler.
View various statistics generated by analyzing the ISA code.
View General Purpose Registers and spill registers allocated for the kernel.
