Bill Dally, PhD

Chief Scientist and SVP of Research

Bill Dally joined NVIDIA as chief scientist in 2009, after 12 years at Stanford University, where he chaired the computer science department. He and his Stanford team developed the system and network architectures, signaling, routing, and synchronization technology found in most large parallel computers today. Previously at MIT, his team built experimental parallel computer systems that pioneered the separation of mechanism from programming models and demonstrated very low overhead synchronization and communication mechanisms. Earlier, at CalTech, he designed the MOSSIM simulation engine and the Torus routing chip, which pioneered “wormhole” routing and virtual-channel flow control. He earned a Ph.D. in computer science from CalTech, holds over 120 patents, has published over 250 papers, and is an author of four textbooks.
