CUDA Programming and Performance Tuning with IBM XL Compilers on POWER8 Systems



The exploitation of general-purpose computing on a heterogeneous parallel system proves to be highly efficient for running several technical computing workloads.  This approach can also apply to a wide range of workloads, such as chemistry, bioinformatics, molecular biology, engineering, and big data analytics.  The Power S822LC featured NVIDIA GPU is built on industry standards and incorporating community innovation from the OpenPOWER Foundation.  This presentation will give an overview of CUDA programming with IBM C/C++ and Fortran compilers and provide performance running tips for different workloads on Power S822LC systems.
