The ALCF will retire Theta (KNL nodes) and Theta-fs0 (Lustre file system mounted on Theta, ThetaGPU, and Cooley) on December 31, 2023. To prepare for theta-fs0 decommissioning, please take action on the data you need to transfer. If you no longer need your files on theta-fs0, there is no need to delete them. We will delete the file systems as part of the storage hardware decommissioning. If you need to move your data, please do it as soon as it possible to your allocation on Grand/Eagle/tape or to your home institution. Refer to our data policy https://docs.alcf.anl.gov/policies/data-and-software-policies/data-policy/ for more information about storage and retention.
