Computing

Important Note

This is an archival area for a variety of documentation and design developed for the LBNE Collaboration which ended its operations to reorganize and merge with DUNE. There isn't any guarantee that the materials presented here are up-to-date or relevant, they are kept here for reference by the computing experts and managers.

Previous Priorities (LBNE Archive)

Priorities for the software and computing work.

• LBNE Software Infrastructure: LBNE code build, validation and continuous integration
• LBNE Geometry Description and Model
• 35t prototype readiness
• File Metadata Schema

• Misc:
  • Data Handling
• Quick links:
  • "Full Scale Prototype Test" at CERN (2017)
  • The 35t LArTPC Prototype Test at FNAL (2015)

Software Tools

LBNE Software

• The Far Detector "lbnecode" package - LArTPC (Redmine Wiki)
• LBNE Far Detector SW releases (lbnecode)

Underlying Software Components and Tools

• art, a ROOT-based suite of tools, libraries, and applications for processing detector events.
• LArSoft, an art-based framework for simulating liquid argon drift detectors. As of Jan 24, 2014, LArSoft transitioned from svn/SRT to git/mrb/ups.
  • Redmine Wiki
  • LArSoft Quick Start Guide

New Tools

• worch, a meta-build orchestration system based on waf framework.
• GGD, a Geometry Description system. Also see this dedicated geometry page.
• "Building in Docker", our R&D for applying the Docker platform to solve the problem of LBNE (and other) software packaging and distribution.

Facilities

FNAL

• Overview of Computing at FNAL (Slides)
• FNAL Accounts
• Grid Monitoring
  • Fermigrid (Central computing facility at FNAL)
  • "FIFEmon"
  • FNAL Grid Accounting scoreboard
  • Fermicloud
  • Garden variety of monitoring stats
• Storage
  • dCache status, dCache space usage
  • Enstore status (mass storage)

BNL

• The RHIC and ATLAS Computing Facility: (RACF)
• The US ATLAS: Facilities Page (useful links)
• BNL Google Search

Open Science Grid

While not a facility or even an owner of a facility, the Open Science Grid (OSG) Consortium is an important component of the national Grid Computing infrastructure in the US as it facilitates access to High-Throughput Computing facilities for many research institutions and collaborations. LBNE enjoys the support of the OSG and has a Virtual Organization (VO) status with the Consortium.

• Gratia monitoring tool which shows Open Science Grid resource utilization.
