NRAO Computing Re-organization Jim Ulvestad (for K.Y. Lo) Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003

EVLA Advisory Committee Meeting Philosophy NRAO computing needs to be more directly connected to the NRAO projects Increase responsiveness to project requirements Focus on project deliverables, without losing sight of a shared vision of data management Put responsibility directly on project managers Seek commonality among projects and telescopes wherever possible Share resources/expertise within NRAO Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003

EVLA Advisory Committee Meeting AIPS++ Structure Disbanded international consortium AIPS++ “Project” is no more, but AIPS++ code base remains The primary purpose of AIPS++ within NRAO now is to satisfy project requirements, not to be a universal software system AIPS++ group renamed the Science Software Group to emphasize this change in focus Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003

Observatory Computing NRAO Data Management split into two parts Computing and Information Services (G. Hunt) Software development personnel distributed among projects and telescopes (Green Bank, EVLA, ALMA, VLA/VLBA Ops) This includes AIPS++ and e2e personnel Observatory Computing Council advises NRAO Director Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003

Interferometry Software Division Co-led by ALMA (B. Glendenning) and VLA/VLBA Operations (J. Ulvestad) Responsible for EVLA, ALMA, VLA/VLBA Incorporates AIPS++ (SSG) and e2e personnel Integrated Product Teams/groups include individuals under ALMA and VLA/VLBA line management Project scientists within IPTs (e.g., Myers in SSG) EVLA and ALMA Software Project Scientists (Butler & Shepherd) ensure that project requirements are met Chief Architect for system- and NRAO-wide issues Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003

Interferometry Software Division Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003

General Computing Issues Can we bring enough resources to bear to accomplish all desired tasks? What is the proper balance between immediate project/telescope requirements and shared long-term goals? What is the achievable long-term vision for data management at NRAO? Ulvestad/Lo EVLA Advisory Committee Meeting September 8-9, 2003
