With energy efficiency and power consumption being the primary impediment in the path to exascale systems, low-power high performance embedded systems are of increasing interest. The Parallella System-on-module (SoM) created by Adapteva combines the Epiphany-IV 64-core coprocessor with a host ARM processor housed in a Zynq System-on-chip. The Epiphany integrates low-power RISC cores on a 2D mesh network...
Graphics processing units (GPUs) can provide excellent speedups on some, but not all, general-purpose workloads. Using a set of computational GPU kernels as examples, the authors show how to adapt kernels to utilize the architectural features of a GeForce 8800 GPU and what finally limits the achievable performance.
In the last few years, GPUs(Graphics Processing Units) have made rapid development. Their ever-increasing computing power and decreasing cost have attracted attention from both industry and academia. In addition to graphics applications, researchers are interested in using them for general purpose computing. Recently, NVIDIA released a new computing architecture, CUDA (compute united device architecture),...
