High Performance Computing

Starting July 1, 2017, the Newton HPC cluster will be managed by the Joint Institute of Computational Sciences (JICS) and become part of the University of Tennessee Advanced Computing Facility (ACF).

May 15, 2017 email sent to all Newton users from Tony Mezzacappa, JICS Director:

In an effort to consolidate computational resources, user support, and investments in both, across the Knoxville campus and across other of the University of Tennessee campuses, the Joint Institute for Computational Sciences this summer will stand up the University of Tennessee Advanced Computing Facility (ACF). The ACF will combine the Newton cluster, the Beacon cluster, and new compute nodes, together with a new high-speed, petascale, parallel file system, to instantiate one of the largest and most balanced university clusters in the Southeast. This is being done with approval, guidance, and oversight from members of the administration at both the Knoxville and Memphis campuses, as well as from UTK faculty (Newton) investors and UTHSC faculty investors. In addition, JICS is involved in ongoing discussions to include other campuses and their faculty in the ACF, to provide an increasingly powerful computational ecosystem for everyone participating.

 The ACF user model will be informed by the Newton user model with regard to institutional and faculty investments and priority and opportunistic use. Newton users should find a familiar framework within which to compute, but access to a larger, balanced system, and to a larger support team. The goal is to improve upon the successful Newton model and program to provide increased resources and increased support (basic to advanced), along with increased flexibility in the types of computation that can be enabled and the scale at which those computations can be performed. Most important, the ACF will be founded upon the increased engagement JICS has established with campus over the past several years.

The transition from Newton to the ACF will be carried out in such a way as to minimize user down time. Specifically, the transition will be done in phases, moving Newton partitions individually. Newton users will not be without a compute platform on which to work at any given time.

 To facilitate matters for current users, we have created an ACF landing page, including a link to the ACF timeline:

The transition timeline may be subject to some change as we move forward. We will post updates as needed to the above website throughout the Summer and Fall.
