Sophia Replacing ThetaGPU

As noted in past weekly updates, with the retirement of Theta, we have decoupled and are reconfiguring ThetaGPU to become a new system named Sophia. 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 in the coming weeks.
