First steps on AMD Fusion

Submitted by flugi on Fri, 02/11/2011 - 10:28

With the arrival of the Fusion platform we decided to tune the code generation of Minotaurus to support AMD GPUs as well. Introducing basic structured OpenCL code generation, the latest AMD driver accepts and runs Minotaurus on Fusion. The speedup is currently suboptimal, the memory management will be tuned also to the special case of Fusion. It can perform now ~30 fps with 512x512 resolution on Zacate. Of course, hand optimized code could do it better, but this is still generated code from C++, using templates and other candies. OpenMP parallelized version of the same code can achieve ~8 fps on the double core Bobcat.

Minotaurus

is our software tool embedded in a C++ compiler that automatically determines during compilation time which parts of the source code should be compiled to GPU (and how) while managing data transfer between CPU and GPU automatically. Our unique technology increases productivity and reduces development effort and time.

Quantum Chemistry

Our BRIAN QC software package helps to reduce time need and costs of discovery phase and to find the right molecule for successful nano-material and drug development projects. It uses compiler technology to generate specific integral calculation kernels for GPUs. The applied compiler enables the adaptation of field specific optimization on a chosen GPU architecture; the conventional solutions cannot compile huge code.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 767912.
