Discussion on Software Agreements and Computing MoU Slide 6 Announcements - FOCUS questions 1. How does your experiment define "frozen OS" support? Frozen support means the possibility of running existing experiment software without modification (e.g. no changes to compiler, libraries, file system, interface to the stager and to tapes etc.). Services used by the experiment, such as the stager, LSF etc. should be maintained in such a way as to allow the experiment software to continue working. Essential bug fixes should be applied to the CERN software libraries, but no new features are requested.

Discussion on Software Agreements and Computing MoU Slide 7 Announcements - FOCUS questions 2. Does your experiment agree with the RISC decommissioning timetable presented by Manuel Delfino at FOCUS 17? (RSPLUS/RSBATCH - No physicist access in 2001, removal end 2001 HPPLUS - Freeze OS end 2001, removal end 2003 CERNLIB - Last maintenance release early 2002 PAW replacement in production mid-2001) No major problems with decommissioning schedule of RISC : our software is currently supported on Linux, WNT and AIX. We have stopped accessing RSPLUS/RSBATCH for production but still use it for debugging of FORTRAN code, due to the superior quality of the debugger compared to ddd on Linux. CERNLIB- no new functionality needed, current version should be compiled for future versions of Linux and Windows OS/compilers. We are actively migrating our software to C++ and expect to have completed much by end of 2001, but we cannot predict when last line of FORTRAN will have been removed from our production software. We request support for PAW until an OO alternative is officially supported by IT division.

Discussion on Software Agreements and Computing MoU Slide 8 Announcements - FOCUS questions 3. What are your experiment's requirements until 2005 concerning import/export of data? Currently we import MonteCarlo data on DLT 7000 from Rutherford and on Redwood from Lyon, as well as via network. Transfers via the network will increase in importance in future. Our current plan is to produce the following volumes of MonteCarlo data in the homelabs, which will be transferred to CERN preferably by network: TB TB TB TB TB In 2005 these numbers increase by two orders of magnitude in both directions (import of simulated data and export of real data)

Discussion on Software Agreements and Computing MoU Slide 9 FOCUS 4. How critical is archiving for your experiment? We make no use of pubarch. Some users archive their data on tapes, others in HSM. It is important that these data are safeguarded in any future migration. 5. What is the 3-year requirement for remote backup? We do not use remote backup for any of our systems.
