Bridges-2, PSC’s newest supercomputer, will debut in 2021.  It will be funded  by a $10-million grant from the National Science Foundation.

Bridges-2 will provide transformative capability for rapidly evolving, computation-intensive and data-intensive research, creating opportunities for collaboration and convergence research. It will support both traditional and non-traditional research communities and applications. Bridges-2 will integrate new technologies for converged, scalable HPC, machine learning and data; prioritize researcher productivity and ease of use; and provide an extensible architecture for interoperation with complementary data-intensive projects, campus resources, and clouds.

Bridges-2 will be available at no cost for research and education, and at cost-recovery rates for other purposes.


Early User Program

The Bridges-2 Early User Program is an opportunity for you to port, tune and optimize your applications early, and make progress on your research. There is no cost to participate in the Early User Program, just as there will be no cost for XSEDE allocations when Bridges-2 enters production.

From Day One you will be able to:

  • Consult the Bridges-2 User Guide
  • Avail yourself of advanced user support
  • Access commonly used software packages and datasets

What we expect from you

We expect that you will achieve real scientific progress during the Early User Program. We also expect you to provide us with feedback on how your experience is going.  We will check in with you weekly to ask about your progress and experience, and at the end of the EUP, you will be asked to complete a short survey. You can send us questions, issues or comments at any time through the website.


Availability of software and datasets

We are interested in what software and datasets would be useful to you in the Early User Program.

The list of software to be installed for the EUP is here.

The datasets that are installed on Bridges will also be installed in Bridges-2 for the EUP.  You can see that list here.


The application deadline for the Early User Program has passed.
