Exploiting Heterogeneous Architectures: Applications and Lessons Learned

Exploiting Heterogeneous Architectures: Applications and Lessons Learned

Stephan, J.

In this talk we show the benefits of using performance portability layers such as alpaka in real-world HPC applications. Using PIConGPU and the CMS Patatrack experiment as examples we demonstrate the minimal porting effort achieved by using alpaka when encountering new and previously unknown hardware architectures.

Keywords: PIConGPU; alpaka; cupla; heterogeneous architectures; heterogeneous systems; heterogeneous programming; C++; performance portability; software portability; HPC
