Priorities

• General Priorities
• "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.
