Abstract :
We present a many-core full system simulation platform and its OpenCL runtime system. The OpenCL runtime system includes an on-the-fly compiler and resource manager for the ARM-based many-core platform. Using this platform, we evaluate approaches of work-item scheduling and memory management in OpenCL memory hierarchy. Our experimental results show that scheduling work-items on a many-core system using general purpose RISC CPU should avoid per work-item context switching. Data deployment and work-item coalescing are the two keys for significant speedup.
