Yes, and IIRC (from the presentation I went to, and for those that don't know) the resource allocation doesn't have to be the whole cluster, they can split it up and run smaller less scalable jobs across just a portion of the hardware. In fact I think they said the vast majority of the jobs are unable to consume the entire cluster. AKA its AWS for HPC. Also AFAIK, that has been the model at TACC for at least a decade, maybe longer.
