Trestles User Guide: System Access
As an XSEDE computing resource, Trestles is accessible to XSEDE users who are given time on the system. In order to get an account, users will need to submit a proposal through the XSEDE Allocation Request System. Interested users may contact SDSC User Support for assistance on applying for time on Trestles (see sidebar for contact information).
In order to serve a large number of moderate-scale users and improve turnaround time, Trestles limits the number of cores per job to 1,024, caps the allocation per individual project to 1.5M SUs/year (gateway projects are exempt from this cap), and limits startup allocations to 50k SUs.
