Summary (2-4 sentences)
The simulation campaigns by the ePIC collaboration have consumed over 10 million core hours,
producing over 300 TB of simulation data on the Open Science Grid since May 2023. The
results are being actively used for the detector and physics studies in preparation for the
Technical Design Report of the ePIC experiment, the first experiment to be conducted at the
future Electron-Ion Collider (EIC) at Brookhaven National Laboratory. The investigation of
electron-proton/ion collisions at ePIC will provide insight into the nucleon and nucleus down to
the scale of sea quarks and gluons.This talk will discuss the ePIC simulation campaigns
experience with submitting from multiple submit nodes, integration of international resources,
reading and writing to XRootD, and identifying and addressing issues related to low throughput
and high failure rate, etc. It will also address the additional future use cases for the ePIC
collaboration, ex: possible access to sites with GPUs for training.
