HEP@home: A Volunteer Computing Project to Run Fast Simulation with Delphes for CEPC

Abstract

Delphes is a C++ framework to perform a fast multipurpose detector response simulation. The Circular Electron Positron Collider (CEPC) experiment runs fast simulation with a modified Delphes based on its own scientific objectives. The CEPC fast simulation with Delphes is a High Throughput Computing (HTC) application with small input and output files. Besides, to compile and run Delphes, only ROOT software is necessary.Therefore, all these features make it appropriate to run CEPC fast simulation as a Volunteer Computing application. As a result, a BOINC project named HEP@home is developed to run fast simulation with Delphes for CEPC. This paper describes the internal structure of the project, pre and post data operations, and its development status.
