Scientific computing plan for the ECCE detector at the Electron Ion Collider

The Electron Ion Collider (EIC) is the next generation of precision QCD facility to be built at Brookhaven National Laboratory in conjunction with Thomas Jefferson Laboratory. There are a significant number software and computing challenges that need overcome EIC. During EIC detector proposal development period, ECCE consortium began identifying addressing these process producing complete based upon detailed physics simulations. In this document, efforts produce discussed; furthermore, model resources required for future described.
