The Need for an R&D and Upgrade Program for CMS Software and Computing

TL;DR

This paper emphasizes the urgent need for an R&D and upgrade program for CMS software and computing to handle the increased data volume and complexity from the LHC's future upgrades.

Contribution

It highlights the necessity of a dedicated R&D program to ensure CMS computing capabilities meet future data analysis demands.

Findings

Increased data volume requires enhanced computing infrastructure.

Current computing performance gains are insufficient for future needs.

A strategic R&D program is essential for CMS to adapt to upcoming challenges.

Abstract

Over the next ten years, the physics reach of the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) will be greatly extended through increases in the instantaneous luminosity of the accelerator and large increases in the amount of collected data. Due to changes in the way Moore's Law computing performance gains have been realized in the past decade, an aggressive program of R&D is needed to ensure that the computing capability of CMS will be up to the task of collecting and analyzing this data.
