In 1999, Page et al. described their algorithm — PageRank — for scoring pages in their web search engine, Google. Already from the start it was clear that due to the large number of pages to be ranked, the PageRank algorithm's efficiency and optimal performance was and is a critical feature. One method of increasing the efficiency of calculations is based on MapReduce, also originally published by...
The Dutch Advanced School for Computing and Imaging has built five generations of a 200-node distributed system over nearly two decades while remaining aligned with the shifting computer science research agenda. The system has supported years of award-winning research, underlining the benefits of investing in a smaller-scale, tailored design.
Applications of High-Performance Computers spans a large intellectual area and now includes all the traditional application science and engineering fields. The end goal of all high performance computing research is eventually to support applications, but those applications have traditionally had a strong feedback effect on computer architecture, hardware design, and systems.
The Complex Streamed Instruction (CSI) set is an architectural paradigm designed to accelerate multimedia applications. These applications are characterized by streaming operations on small-width data elements such as 8-bit pixels or 16-bit audio samples. CSI instructions operate on two-dimensional data streams in a SIMD fashion and are able to process streams of arbitrary length. In this paper we...
