GPUs and Deep Learning
Deep learning, or deep neural nets (DNNs), is the technical craze these days. It is targeting everything from self-driving cars to tagging photos. DNNs are just one of many artificial intelligence (AI) research areas. It has become more popular as processor performance has increased, allowing more complex systems. DNNs require matrix number-crunching capabilities found in FPGAs and GPUs. GPUs are now the target for a number of DNN platforms. NVidia’s Tesla P100 GPU (Fig. 1) is designed to tackle applications like deep learning neural nets. The Tesla P100 can deliver 21 TFLOPS of 16-bit floating point that is ideal for DNN applications. It employs CoWoS (Chip-on Wafer-on-Substrate) with HBM2 (high-bandwidth memory version 2) technology. AMD used HBM on its Radeon R9 GPU (see “Best of 2015: High Bandwidth Memory Helps…
