A collaboration that began 16 years ago between computer scientists at the USC Information Sciences Institute (ISI) and members of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo projects is opening up a new window onto the nature of the universe. Pegasus, a specialized computer program developed by a … Read More
By Emily Gersema, USC News The Nobel Prize-winning discovery that gravitational waves exist in the universe, which in turn further confirmed Albert Einstein’s General Theory of Relativity, was made possible in part by a collaboration with USC computer scientists. By developing a specialized computer program called Pegasus, a team … Read More
The Pegasus team is pleased to announce that it has received a new grant from the National Science Foundation to support new development and maintenance of the Pegasus Workflow Management System. It will support Pegasus for the next 5 years and help address the needs of our diverse user community. … Read More
Blue Waters provides a series of free webinars throughout the year. The Scientific Workflows webinar track provides an overview of common scientific workflows and tools that enable them. In the first presentation of series of webinars, Scott Callaghan presented an overview of scientific workflows, where he discussed what the community … Read More
The Pegasus team is very happy to hear about the cutting-edge research and development that can help solve some of the challenges associated with drug delivery discovery: “The motions of a tRNA (or transfer RNA) model system can be enhanced when coupled with nanodiamonds, or diamond nanoparticles approximately 5 to … Read More
The three-year project, Scientific Workflow Integrity with Pegasus, is funded by a $1 million grant from the National Science Foundation (NSF) as part of its Cybersecurity Innovation for Cyberinfrastructure (CICI) program. Von Welch, director of IU’s Center for Applied Cybersecurity Research (CACR), is the project’s principal investigator. The Pegasus Workflow … Read More
TACC (Texas Advanced Computing Center) has published a science highlight of the SoyKB project. Pegasus is used to orchestrate the computations running on TACC Wrangler and automatically retrieving and storing data in the CyVerse data store. Also highlighted is how the XSEDE ECSS (Extended Collaborative Support Service) can be used … Read More
Pegasus (est. 2001) has been widely adopted by the computational research community, and its performance and usage data have already demonstrated its ability to empower the scientists to seamlessly run their simulation or data analyses in distributed systems. In this project, we aim to provide empirical data to demonstrate on … Read More
Early this month, the Pegasus team was very excited to hear about LIGO’s incredible discovery: the first detection of gravitational waves from colliding black holes. Since then, LIGO and Pegasus have been featured in several media channels. Below, we summarize some of these publications. Additionally, we provide the link to … Read More
