Lonestar 5 in Now in Production

ITS Staff,

Lonestar 5, https://www.tacc.utexas.edu/web/website/systems/lonestar , the latest high performance computer at the Texas Advanced Computing Center (TACC) at The University of Texas at Austin, is now in full production. This is TACC’s second petascale system, which is primed to play a large role in advancing scientific and engineering research across the State of Texas and beyond. This resource is sponsored by The University of Texas System (UT System), in partnership with UT Austin, Texas Tech University, Texas A&M University, the Institute for Computational Engineering and Sciences (ICES) and the Center for Space Research at The University of Texas at Austin. The technology partners are Cray Inc., Intel Inc. and DataDirect Networks. A funding partner is the National Science Foundation (NSF).

Lonestar 5 serves as the chief high performance computing resource in the UT Research Cyberinfrastructure (UTRC)  initiative. UTRC offers researchers a combination of advanced computational systems, large data storage, and high bandwidth data access, enabling researchers within all UT System institutions to collaborate with one another and to compete at the vanguard of scientific exploration and discovery. Lonestar 5 provides researchers with access to a 30,000 core, 1.2 PetaFlop Cray XC40 which has been customized by TACC staff to meet the diverse needs of the computational researcher community. (A petaflop is the ability of a computer to do one quadrillion floating point operations per second (FLOPS) and can be measured as one thousand teraflops.)

Researchers using Lonestar 5 in an early user mode have been impressed with the capabilities of the new system and the level of support received from TACC staff. The new system is already being lauded as a phenomenal asset for the computational science community of Texas. UT System affiliated researchers and contributing partners can request access to Lonestar 5 via the TACC User Portal. Kudos to our world-class colleagues at TACC for this most recent ground-breaking achievement.

To address one of our IT governance priorities this year, we are launching a collaborative initiative with TACC, the Office of the Vice President for Research, the University of Texas Libraries, and Information Technology Services to focus on clearly defining and better communicating the vast research computing resources available to researchers at the University. We will be working with the Research and Educational Technology, Faculty Council IT (C-13), and IT Architecture and Infrastructure IT governance committees. I’ll keep you posted on the progress.

Have a fun weekend!
