Anton is a special purpose supercomputer for biomolecular simulation designed and constructed by D. E. Shaw Research (DESRES). PSC's current system is known as Anton 2 and is a successor to the original Anton 1 machine hosted here.

Anton 2, the next-generation Anton supercomputer, is a 128 node system, made available without cost by DESRES for non-commercial research use by US universities and other not-for-profit institutions, and is hosted by PSC with support from the NIH National Institute of General Medical Sciences.

Anton was designed to dramatically increase the speed of molecular dynamics (MD) simulations compared with the previous state of the art, allowing biomedical researchers to understand the motions and interactions of proteins and other biologically important molecules over much longer time periods than was previously accessible to computational study. The MD research community is using the Anton 2 machine at PSC to investigate important biological phenomena that due to their intrinsically long time scales have been outside the reach of even the most powerful general-purpose scientific computers. Application areas include biomolecular energy transformation, ion channel selectivity and gating, drug interactions with proteins and nucleic acids, protein folding and protein-membrane signaling.

TACC's High Performance Computing (HPC) systems are used primarily for scientific computing and while their disk systems are large, they are unable to store the long-term final data generated on these systems. The Ranch archive system fills this need for high capacity long-term storage, by providing a massive high performance file system and tape-based backing store designed, implemented, and supported specifically for archival purposes. <br/><br/>Ranch is a Quantum StorNext-based system, with a DDN- provided front-end disk system (30PB raw), and a 5000 slot Quantum Scalar i6000 library for its back-end tape archive. <br/><br>Ranch is an allocated resource, meaning that Ranch is available only to users with an allocation on one of TACC's computational resources such as Frontera, Stampede3, or Lonestar6. ACCESS PIs will be prompted automatically for the companion storage allocation as part of the proposal submission process and should include a justification of the storage needs in their proposal. The default allocation on Ranch for users is 2TB. To request a shared Ranch project space for your team's use, please submit a TACC Helpdesk ticket.
