On XSEDE, what is Lonestar (TACC)?

On the Extreme Science and Engineering Discovery Environment (XSEDE), Lonestar (lonestar.tacc.utexas.edu) is the Dell PowerEdge Linux cluster at the Texas Advanced Computing Center (TACC), at the University of Texas at Austin.

Lonestar is intended primarily for parallel applications scalable to thousands of cores. Normal batch queues enable users to run simulations up to 24 hours. Jobs requiring run times and more cores than allowed by the normal queues can be run in a special queue with approval of TACC staff.

For system specifications and user documentation, see the Lonestar user guide.
