New Approach to Computationally Designing Drugs for GPCRs

Sep 8, 2016 |

Modeling protein interactions with drugs has long been computationally challenging. One obstacle is these interactions often take relatively long to occur and conventional molecular dynamics simulation is insufficient. This week a group of researchers, using several EXSEDE supercomputers, report a hybrid in silico-experimental approach that shows promise as a drug design tool for use with G protein-coupled receptors (GPCRs)

TACC Director Lays Out Details of 2nd-Gen Stampede System

Jun 2, 2016 |

With a $30 million award from the National Science Foundation announced today, the Texas Advanced Computing Center (TACC) at The University of Texas at Austin (UT Austin) will stand up a second-generation Stampede system based on Dell PowerEdge servers equipped with Intel “Knights Landing” processors, next-generation Xeon chips and future 3D XPoint memory.

TACC Drug Discovery Portal Empowers Researchers Worldwide

Oct 22, 2015 |

Where do you turn if you are a researcher who needs to quickly identify drug candidates for diseases ranging from obesity to tuberculosis to leishmaniasis, a tropical disease caused by the bite of a sand fly? You turn to the DrugDiscovery@TACC portal, which is currently helping more than 100 researchers worldwide model, simulate and generate Read more…

XSEDE Resources Fuel Investigation of Model Human Origins

Aug 20, 2015 |

A mix of data- and computation-intensive XSEDE resources are enabling researchers to scale up their climate, vegetation and agent-based human behavior models to tackle fundamental questions of how Homo sapiens came to dominate the planet, according to archeologist Colin Wren of Arizona State University (ASU). The international collaboration, led by Curtis Marean of ASU, will Read more…

Cray Comes Back to TACC

Jul 20, 2015 |

Last week, the Texas Advanced Computing Center (TACC) revealed that it would be continuing the legacy of the Lonestar supercomputer series and reviving its relationship with Cray, the supercomputer maker behind the very first Lonestar system (circa 1997-2002). The original Lonestar was a 50-gigaflops Cray T3E with 88 processsors. With Lonestar 5, TACC is installing Read more…

Texas Supercomputers Contribute to Cancer Hotspot Discovery

Jun 22, 2015 |

Powerful supercomputers around the country continue to push advances in critical areas, such as cancer research. One of the latest such success stories comes out of The University of Texas at Austin, where Texas Advanced Computing Center machines revealed a connection between cross-shaped (cruciform) DNA segments and human cancers. By shedding light on the pathways involved in Read more…

Supercomputing Sheds Light on Party Polarization

Apr 7, 2015 |

What can supercomputers tell us about the way that government operates, or in some cases doesn’t operate? Quite a bit, actually. In a new feature piece on the Texas Advanced Computing Center website, science writer Makeda Easter shares how one TACC researcher is using the center’s Stampede supercomputer to analyze the link between federal spending priorities Read more…

Study Points to Big Bang of Bird Evolution

Dec 15, 2014 |

An international consortium comprised of hundreds of scientists from around the world has successfully decoded the avian genome. The multi-year project harnessed the power of nine supercomputers and 400 years of computing time to sequence, assemble and compare the full genomes of 48 bird species, shedding light on a wide range of avian evolutionary diversity. The Read more…

Deconstructing the Hummingbird’s Hover

Sep 2, 2014 |

Ever wonder how a hummingbird is able to hover in mid-air, appearing for a moment to defy the laws of gravity? You’re not alone. Vanderbilt University mechanical engineer Haoxiang Luo accessed the XSEDE’s Lonestar supercomputer to run 3D simulations of a hummingbird flight in an attempt to deconstruct its mysterious powers. Science Writer Jorge Salazar details Luo’s Read more…

Supercomputing Facilitates Breakthrough Cancer Treatment

Aug 25, 2014 |

MD Anderson Cancer Center researchers are relying on a powerful supercomputer to develop a dosing protocol for an MRI-guided radiation therapy for cancer care, called MRI-linac. The Lonestar system at the Texas Advanced Computing Center (TACC) is helping researchers fine-tune the radiation dosing mechanism so that just the right amount of radiation is delivered to the Read more…
