Abstract
The Project 8 collaboration aims to measure the absolute neutrino mass or improve on the current limit by measuring the tritium beta decay electron spectrum. We present the current distributed computing model for the Project 8 experiment. Project 8 is in its second phase of data taking with a near continuous data rate of 1Gbps. The current computing model uses DIRAC (Distributed Infrastructure with Remote Agent Control) for its workflow and data management. A detailed meta-data assignment using the DIRAC File Catalog is used to automate raw data transfers and subsequent stages of data processing. The DIRAC system is deployed on containers managed using a Kubernetes cluster to provide a scalable infrastructure. A modified DIRAC Site Director provides the ability to submit jobs using Singularity on opportunistic High-Performance Computing (HPC) sites.
Highlights
The goal of the Project 8 experiment [1] is to measure the absolute neutrino mass using tritium beta decays
We will provide a summary of the current Project 8 computing model
The computing system was designed to handle a large amount of data and the ability to dynamically integrate a variety of geographically distributed computing resources
Summary
The goal of the Project 8 experiment [1] is to measure the absolute neutrino mass using tritium beta decays. The approach taken by the collaboration is to make this measurement using a new method of electron spectroscopy, Cyclotron Radiation Emission Spectroscopy (CRES). In order to demonstrate the new method and achieve the overall goal, the experiment is scheduled to have 4 phases each demonstrating the ability to deliver key technical milestones.
