Key Points

Introduction

---

• Simulation campaigns run on a regular (monthly) basis
• Input requests must be formatted in a specific way and meet certain pre-requisites
• Rucio is the primary way to browse and access simulated EIC/ePIC data

Rucio Usage

---

• Rucio works with datasets and Data Identifiers (DIDs)
• ePIC DIDs may look or be formatted like a nested filepath, but they are flat
• Tags can be used to quickly sort and find data of interest
• Once you find the file location with Rucio, you can use xrootd to download or stream it too

Use Cases

---

• Files from datasets can be directly streamed in analysis scripts
• Files (or whole datasets) can be downloaded locally, but this is usually not needed
