FPGAs have emerged as a cost-effective accelerator alternative in clouds and clusters. Programmability remains a challenge, however, with OpenCL being generally recognized as a likely part of the solution. In this work we seek to advance the use of OpenCL for HPC on FPGAs in two ways. The first is by examining a core HPC application, Molecular Dynamics. The second is by examining a fundamental design...
GPUs have emerged as general-purpose accelerators in high-performance computing (HPC) and scientific applications. However, the reliability characteristics of GPU applications have not been investigated in depth. While error propagation has been extensively investigated for non-GPU applications, GPU applications have a very different programming model which can have a significant effect on error propagation...
This paper proposes a context directed pattern matching (CDPM) mechanism, which employs the context of the coarse-grained reconfigurable arrays (CGRAs) as a guide to improve cache prefetching accuracy. CDPM generates a prefetch pattern for an initially executed context, and reuses the pattern to issue prefetch requests when the context is again executed on CGRA. To eliminate the outdated prefetch...
