Big Red II will be retired from service on December 15, 2019. After that date, you will no longer be able to log into Big Red II; however, the data in your Big Red II home directory will remain accessible from your home directory on any of the other IU research supercomputers. New software requests for Big Red II will no longer be accepted after the October 13, 2019, maintenance window.
Beginning October 14, 2019, IU graduate students, faculty, and staff will be able to create accounts on Big Red III. Undergraduate students and affiliates will be able to get accounts if they are sponsored by full-time IU faculty or staff members. Grand Challenge users who create Big Red III accounts will be able to request exclusive access to a portion of the system for running jobs.

Big Red II is Indiana University's main system for high-performance parallel computing. With a theoretical peak performance (Rpeak) of one thousand trillion floating-point operations per second (1 petaFLOPS) and a maximal achieved performance (Rmax) of 596.4 teraFLOPS, Big Red II is among the world's fastest research supercomputers. Owned and operated solely by IU, Big Red II is designed to accelerate discovery in a wide variety of fields, including medicine, physics, fine arts, and global climate research, and enable effective analysis of large, complex data sets (big data).
