Bill Dally

Chief scientist and SVP of Research at NVIDIA; co-author of Deep Compression; former Stanford CS chair

  • Chief scientist and senior vice president of NVIDIA Research, NVIDIA124

Bill Dally is chief scientist at NVIDIA and senior vice president of NVIDIA Research, which Dally joined in 2009 after 12 years at Stanford University, where Dally chaired the computer science department. Before Stanford, Dally's team at MIT built the J-Machine and M-Machine experimental parallel computers, and at Caltech Dally designed the MOSSIM Simulation Engine and the Torus Routing chip. With Song Han and Huizi Mao, Dally co-authored Deep Compression (2015), which shrinks neural networks through pruning, trained quantization and Huffman coding. NVIDIA's pages list Dally as a member of the National Academy of Engineering, a Fellow of the American Academy of Arts & Sciences, the IEEE and the ACM, and a recipient of the ACM Eckert-Mauchly Award, the IEEE Seymour Cray Award and the ACM Maurice Wilkes Award.123

Work

  • Deep Compression (external site: arxiv.org)Published research

    Co-author, with Song Han and Huizi Mao, of "Deep Compression: Compressing Deep Neural Networks with Pruning, Trained Quantization and Huffman Coding" (2015), which reports shrinking AlexNet and VGG-16 storage without loss of accuracy.3

  • J-Machine and M-Machine

    At MIT from 1986 to 1997, Dally and team built the J-Machine and M-Machine experimental parallel computer systems, which separated mechanism from programming models and showed low-overhead synchronization and communication.2
