  1. ALMA Software B.E. Glendenning (NRAO)

  2. ALMA • “High Frequency VLA” in Chile • Presently a European/North American Project • Japan is almost certainly joining • $1B final cost

  3. Chajnantor Site, Chile5000m

  4. VLA Comparison VLA ALMA N 27 64 D 25 m 12 m l 7 mm 0.35 mm

  5. ALMA Computing • Computing: • Software development • Necessary operational computer equipment • System/network planning and administration (operations phases) • Subsystems: proposal preparation, monitoring, dynamic scheduling, equipment control and calibration, correlator control and processing, archiving, automated pipeline processing, offline processing • Not: embedded software (hardware groups), algorithm development (Science) • Activities: management, requirements, analysis, common software, software engineering, integration and test

  6. ALMA Computing Budget • 230 FTE-y of software development effort on the construction budget • 110 FTE-y of software maintenance and system and network administration effort on the interim operations budget starting in 2007.5. • ~3 FTE/y in-kind contributions to augment baseline systems in various areas (e.g., Archive, ACS) • ~10 FTE/y in NRAO and ESO institutional development of AIPS++, NGAST • ~50 FTE/y • $7.1M of equipment required to operate ALMA on the construction budget. • $3.8M of communications costs and equipment upgrades on the interim operations budget starting in 2007.5. • The above does not include impacts of the operations plan or the Japanese enhancements.

  7. Software Scope • From the cradle… • Proposal Preparation • Proposal Review • Program Preparation • Dynamic Scheduling of Programs • Observation • Calibration & Imaging • Data Delivery & Archiving • Afterlife: • Archival Research & VO Compliance

  8. And it has to look easy… • From the Scientific Software Requirements: • “The ALMA software shall offer an easy to use interface to any user and should not assume detailed knowledge of millimeter astronomy and of the ALMA hardware. • “The general user shall be offered fully supported, standard observing modes to achieve the project goals, expressed in terms of science parameters rather than technical quantities...” • The expert must still be able to exercise full control • But what is simple for the user will therefore becomplexfor the software developer. • Architecture should relieve developer of unnecessary complexity • Separation of functional from technical concerns
