Multi-GPU DGEMM and High Performance Linpack on Highly Energy-Efficient Clusters
D. Røhr, Matthias Jakob Bach, Matthias Kretz, V. Lindenstruth · IEEE Micro · 2011
High Performance Linpack can maximize requirements throughout a computer system. An efficient multi-GPU double-precision general matrix multiply (DGEMM), together with adjustments to the HPL, is required to utilize a heterogeneous computer to its full extent. The authors present the resulting energy-efficiency measurements and suggest a cluster design that can utilize multiple GPUs.
