Gateway downtime: 2021 March 25th Thursday from 8:00 am – 10:00 am (Eastern Time) Downtime is for mandatory system update with new features. Please use shared queues if you donot use all 128 cores available on Bridges2 and Expanse. Please set the core count in Create Experiment to the numer of processors you request in the input if any.

About the Project


Principal Investigator

Dr. Sudhakar Pamidighantam


The SEAGrid science gateway is led by Dr. Sudhakar Pamidighantam and powered by the NSF-funded SciGaP project. This gateway is an agile platform suitable for both research and teaching in science and engineering disciplines.

Bio: Dr. Pamidighantam is a senior member of the Cyberinfrastructure Integration Research Center at Indiana University. Dr. Pamidighantam had been a senior research scientist at NCSA at the University of Illinois at Urbana-Champaign supporting computational chemistry and science gateways development in support of molecular sciences faculty. He serves XSEDE organization as an ECSS consultant and conducts research in computational chemistry. See here for Dr. Pamidighantam’s Google Scholar profile.

Applications Supported:


Usage: SEAGrid has been in operation since 2005 and serves more than 1500 scientists and students. Over this time, SEAGrid has supported and enabled more than 250 publications, 90 conference presentations, at least 25 graduate MS and Ph.D. theses. Since Jan 2015, SEAGrid has served close to 173M XD SUs to support almost 140,000 jobs.

Support: SEAGrid is operated and supported by Indiana University. SEAGrid was developed through awards #0823041 and #1339774 from the National Science Foundation. SEAGrid’s computing resources are provided by a community allocations from the NSF XSEDE program and from individual university HPC centers.  Please contact us if you would like to help support SEAGrid and its mission to enable computational chemistry research for users around the world. Previous NSF support includes awards The SEAGrid gateway is a production community cyberinfrastructure resource developed under the NSF Middleware Initiative (NMI: Deployment) and supported by additional advanced support through XSEDE ASTA and ECSS program activities. An OGCE project funded by NSF enabled the SEAGrid gateway to adapt sustainable middleware.
