PSC’s newest supercomputer
Bridges-2 partition status
Bridges-2
Bridges-2, PSC’s newest supercomputer, began production operations in March 2021. It is funded by a $10-million grant from the National Science Foundation.
Bridges-2 provides transformative capability for rapidly evolving, computation-intensive and data-intensive research, creating opportunities for collaboration and convergence research. It supports both traditional and non-traditional research communities and applications. Bridges-2 is integrating new technologies for converged, scalable HPC, machine learning and data; prioritizing researcher productivity and ease of use; and providing an extensible architecture for interoperation with complementary data-intensive projects, campus resources, and clouds.
Bridges-2 is available at no cost for research and education, and at cost-recovery rates for other purposes.
