The most modern supercomputers are clusters of computing nodes with a heterogeneous architecture; in such a node we can see both classical CPUs and specialized computing coprocessors (GPU-or MIC-based). Modern benchmark tests are oriented either for CPU or for specific coprocessor calculations — but not in a whole thing. This article is dedicated to describe an approach to build a unified performance...
An Open Ethernet Drive (OED) is a new technology that encloses into a hard drive (HDD or SSD) a low-power processor, a fixed-size memory and an Ethernet card. In this study, we thoroughly evaluate the performance of such device and the energy requirements to operate it. The results show that first it is a viable solution to offload data-intensive computations on the OED while maintaining a reasonable...
Recently, a variety of accelerator architectures became available in the field of high performance computing. Intel's MIC (Many Integrated Core) and both GPU architectures, NVIDIA's Kepler and AMD's Graphics Core Next, all represent the latest innovation in the field of general purpose computing accelerators. This paper explores several important characteristics of these architectures and investigates...
