Local and distant communications with the computer systems at the Texas Advanced Computing Center
are made possible by a series of efficient networks managed by ITS Telecommunication and
Networking Services (TNS) and the University of Texas System Office of Telecommunication Services
(OTS). In addition, TACC manages a connection to the NSF TeraGrid high speed backbone.
Internet2 Abilene Network
The University of Texas at Austin is a Charter member of Internet2. The current 655Mbps OC12 connection from UT-Austin to Internet2 will soon change to a 1GigE connection.
Texas Higher Education Network (THEnet)
The University of Texas at Austin is a charter member of THEnet, a state-wide
telecommunications network that connects Texas colleges, universities, research
institutions and their industrial partners. Through the services of THEnet,
researchers anywhere on the Internet can access the advanced scientific computers at
TACC.
University of Texas Network (UTnet)
UTnet is a campus-wide high speed digital data network that provides network access
to all computer users at the University of Texas at Austin. UTNet backbones operate
at 100 Mbps and the Pickle Research Campus is connected to the UT Austin main
campus over a
10GigE
fiberoptic link as part of the Greater Austin Area
Telecommunications Network (GAATN).
TeraGrid
TeraGrid is
an open scientific discovery infrastructure combining leadership class resources to create an integrated, persistent computational resource. TACC is one of eight TeraGrid partner sites that bring over 40 teraflops of computing power, nearly 2 petabytes of rotating storage, and specialized data analysis and visualization resources into production. Partner sites comprise a dedicated 10-30 Gbps network backbone . TACC’s 10Gbps OC192 connection to the TeraGrid traverses the Lonestar Education And Research Network (LEARN) for Texas higher education institutions as well as the National Lambda Rail (NLR).
