  The Intensity Frontier (IF) is a primary focus of the U.S.-based particle
physics program. It encompasses a large spectrum of physics, including quark
flavor physics, charged lepton processes, neutrinos, baryon number violation,
new light weakly-coupled particles, and nucleons, nuclei and atoms. There are
many experiments, a range of scales in data output and throughput, and a wide
range in the number of experimenters. The experiments, projects and theory in
this area all require demanding computing capabilities and technologies. The IF
experiments have significant computing requirements for simulation, theory and
modeling, beam line and experiment design, triggers and DAQ, online monitoring,
event reconstruction and processing, and physics analysis. We have conducted a
qualitative survey of the current and near-term future experiments in the IF to
understand the computing demands of this area and their expected evolution.
This report details the expected computing requirements for the IF in the
context of the Snowmass Community Summer Study 2013.
