  1. Software Development Introduction 18-month Chronology Organization Key Issues EVLA Advisory Committee December 14-15, 2004

  2. 18-month Chronology • Spring 2003: International AIPS++ Project dissolved • 6/2003: Interferometry S/W Division formed, absorbing AIPS++. Project-oriented focus begins • 8/2003: EVLA Computing formed, including e2e part of Data Management • 11/2003: EVLA S/W Project Scientist named • 12/2003-6/2004: Overall high-level S/W design • FY04: EVLA begins funding 1/3 of AIPS++ • Summer 2004: Overall and S/W transition plans begin • Summer 2004: AIPS++ passes ALMA CDR2 • 10/2004: Begin developing EVLA deliverables in AIPS++ EVLA Advisory Committee December 14-15, 2004

  3. Organization • Interferometry S/W Division includes development common to several NRAO telescopes • Response to EVLA needs improved • e2e oversight committee addresses commonality among various projects • EVLA e2e contains 4 FTEs, most responsible for observatory-wide deliverables • NRAO plans search for observatory-wide software development coordinator EVLA Advisory Committee December 14-15, 2004

  4. Key Issues • EVLA is taking on more responsibility and costs of software development • VLA must be kept operational during EVLA development • EVLA presents novel post-processing problems, and we need a better model of how astronomers will reduce EVLA data • Desire for extensive e2e capabilities not matched by available funding • Maximize borrowing/re-use of ALMA developments EVLA Advisory Committee December 14-15, 2004
