Pegasus powers LIGO gravitational wave detection analysis
The Pegasus team is very happy to hear about LIGO’s incredible discovery: the first detection of gravitational waves from colliding black holes. We congratulate the entire LIGO Scientific Collaboration and the Virgo Collaboration on this incredible achievement.
The Pegasus team is very pleased to have contributed to LIGO’s software infrastructure. One of the main analysis pipelines used by LIGO to detect the gravitational wave was executed using Pegasus Workflow Management System (WMS). The PyCBC analysis pipeline analyzed data from the two LIGO detectors. Initially the analysis was managed by Pegasus WMS on the LIGO Data Grid. LIGO extended their computations to the nation-wide cyber-infrastructures, Open Science Grid and XSEDE. Pegasus aided this expansion by managing cross-site data transfers and computations in a reliable, scalable, and efficient manner. Pegasus enables LIGO researchers to easily monitor and analyze their workflows via a web based dashboard, and a suite of command line tools.

Diamonds that Deliver!
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 10 nanometers in size”. The discovery involved ORNL's Spallation Neutron Source, which provides the most intense pulsed neutron beams in the world for scientific research and industrial development, and ORNL's Titan supercomputer, the nation's most powerful for open science. By comparing the SNS neutron scattering data with the data from the team's molecular dynamics simulations on Titan, the researchers have confirmed that nanodiamonds enhance the dynamics of tRNA when in the presence of water; This analysis was performed with the Pegasus WMS.
