Indiana University's Karst research supercomputer was retired from service on December 18, 2020. Here is what you need to know about the retirement:

Although you can no longer log into Karst, data in Karst home directories will remain accessible from the other IU research supercomputers through December 31, 2021.
UITS Research Technologies is preparing a replacement system called Quartz with significantly more compute power than Karst. Quartz will comprise 92 compute nodes, each equipped with two 64-core CPUs and 512 GB of RAM, and will be available for use by all IU students, faculty, and staff. UITS will share further details about the new system's configuration and availability in the coming months.

For information about current system, see Supercomputers for academic research at IU.
