Performance of the NVIDIA Jetson TK1 in HPC

The NVIDIA Jetson is demonstrated as a competitive HPC platform. The Jetson has 192 Kepler CUDA cores that are "true" in that they share a processor: in the case of the Jetson, a 32-bit ARM Cortex-A15 variant low power architecture. Our work explores the use cases of the Jetson TK1 board as an interface device for cloud computing, and also as a scalable device for energy efficient HPC. We evaluate the performance of the unified memory structure of the TK1 and also the power-performance ratio, as well as energy use, when executing co-scheduled applications.
