Jetstream2 Allocations Overview

Access to Jetstream2 is available solely through Xtreme Science and Engineering Discovery Environment (XSEDE) allocations. You must be on a valid allocation or the PI of a valid allocation to have access to Jetstream2.

Jetstream allocations are awarded exclusively through XSEDE. XSEDE provides XSEDE User Portal (XUP) accounts free of charge. XSEDE allocations require that the Principal Investigator (PI) be a US-based researcher.

A guide with more detail on Jetstream allocations is available online at the XSEDE Resource Information page.

Allocation types:

  • Trial allocation - Limited in hours and cores, non-renewable, meant to explore using Jetstream2
  • Startup allocation - For smaller scale research or exploratory usage before applying for a larger research allocation. Not intended for any courses or workshops.
  • Education allocation - For workshops, tutorials, or courses. Startup limits may not apply.
  • Research allocation - Larger scale allocations intended for research. Limits are generally only in what the PI can justify requesting.

You’ll need to have an XSEDE Portal account to request access to the Jetstream2 Trial Allocation, be added to a PI’s allocation, or apply for an allocation.
