Learning and adapting with OSG: Investigating the strong nuclear force

David Swanson Memorial Award winner, Connor Natzke’s journey with the OSG Consortium began in 2019 as a student of the OSG User School. Today, nearly three years later, Natzke has executed 600,000 simulations with the help of OSG staff and prior OSG programming. These simulations, each of them submitted as a job, logged over 135,000 core hours provided by the Open Science Pool (OSPool). Natzke’s history with the OSG Consortium reflects a pattern of learning, adapting, and improving that translates to the acceleration and expansion of scientific discovery.

OSPool Usage Hits Daily Record

Researchers utilizing the OSPool are racking up record-breaking numbers. On June 8, the OSPool, which provides computing resources to researchers across the country, went over 1.1 million core hours –– a daily record number. To put this in perspective, one million core hours is equivalent to using 42 thousand cores in just one day. That is close to half the size of some large supercomputing centers. In short, an increasing number of researchers are utilizing the OSG to carry out an incredible amount of computing.
