With the retirement of Theta, we are decoupling and reconfiguring ThetaGPU to become a new system named Sophia. Scheduling on ThetaGPU will be halted on December 31, 2023. Sophia will have two new primary purposes: to run JupyterHub instances and to train Large Language Models. PBSPro will be the system’s scheduler. We'll provide additional information about Sophia at the start of the new year.
