### Abstract

While over the past years significant experience for using GPUs with processors based on the x86 ISA has been obtained, GPU-accelerated systems with POWER processors have become available only very recently. In this talk we report on early experiences of porting selected scientific applications to GPU-accelerated POWER8 systems. We will explore basic performance features through micro-benchmarks, but our main focus will be on results for full applications or mini-applications. These have been selected such that hardware characteristics can be explored for applications with significantly different performance signatures. The application domains range from physics to life sciences and have in common that they are in need of supercomputing resources. Particular attention will be given to performance analysis capabilities of the system and the available software tools. We finally will report on a newly established POWER Acceleration and Design Center, which has the goal of providing support to scientists in using OpenPOWER technologies.
