Deep Learning (DL) algorithms have become ubiquitous in data analytics. As a result, major computing vendors — including NVIDIA, Intel, AMD and IBM — have architectural road-maps influenced by DL workloads. Furthermore, several vendors have recently advertised new computing products as accelerating DL workloads. Unfortunately, it is difficult for data scientists to quantify the potential of these...
Determining key characteristics of High Performance Computing machines that allow users to predict their performance is an old and recurrent dream. This was, for example, the rationale behind the design of the LogP model that later evolved into many variants (LogGP, LogGPS, LoGPS, ) to cope with the evolution and complexity of network technology. Although the network has received a lot of attention,...
Today's supercomputers are moving towards deployment of many-core processors like Intel Xeon Phi Knights Landing (KNL), to deliver high compute and memory capacity. Applications executing on such many-core platforms with improved vectorization require high memory bandwidth. To improve performance, architectures like Knights Landing include a high bandwidth and low capacity in-package high bandwidth...
