PSC's "Bridges" was the first system to successfully converge HPC, AI, and Big Data. Designed for the U.S. national research community and supported by NSF, it now serves approximately 1600 projects and 7500 users at over 350 institutions. Bridges emphasizes "nontraditional" uses that span the life, physical, and social sciences, engineering, and business, many of which are based on AI or AI-enabled simulation. We describe the characteristics of Bridges that have made it a success, and we highlight several inspirational results and how they benefited from the system architecture. We then introduce "Bridges AI", a powerful new addition for balanced AI capability and capacity that includes NVIDIA's DGX-2 and HPE NVLink-connected 8-way Volta servers.
