Jim -----Original Message----- From: Nigel Hambly [mailto:nch@roe.ac.uk] Sent: 23 May 2003 11:46 To: WFCAM Science Archive Team -- Clive Davenhall; Eckhard Sutorius; Harvey MacGillivray; Ian Bond; Mike Read; Nigel Hambly; Bob Mann Cc: Andrew Lawrence; Peredur Williams; Andy Adamson; Jim Emerson Subject: WFAU WSA weekly meeting minutes: 23 May 2003 Minutes of WFCAM Science Archive meeting: 23 May 2003 ----------------------------------------------------- ----------------------------------------------------- Present: NCH, ETWS, HMG, IAB, PMW, JMS Apologies: RGM, AL, MAR Actions discharged: ------------------- ACTION: AL, NCH & PMW to progress with VDFS continuation proposal (telecon in the first instance). ACTION: PMW to formally reply to Luc/FE/JL (cc JPE & AA) thanking them for the CDR report, and state our plans to respond. ACTION: ETWS, MAR & NCH to read the SADD and get comments back to IAB by close of play on Wed - all done and discharged (thanks to all concerned!) Actions partly discharged but continuing: ----------------------------------------- ACTION: PMW to draft and action plan in the light of the review panel report. ACTION: ALL to review risk register and think of any new internal or external risks that should be documented in the risk register. ACTION: IAB to do next iteration of SADD by the next meeting. - continuing; thanks for progressing these. Actions carried forward from 16/05/03 meeting: ---------------------------------------------- ACTION: PMW to liaise with AL to make sure that Compute Support are made aware, from the highest "official" level, of our requirements, re. 100 Gbyte/day transfer from CASU, and to impress on them that the 1 Gbit/s FW should be their highest priority. - CONTINUES Specific points and new actions: -------------------------------- Project management: NCH reported that he and PMW had worked all week on the VDFS continuation proposal (VDFS has now been absorbed into a larger road-map proposal called VEGA). Proposal development can be viewed at http://casse.ast.cam.ac.uk/twiki/bin/view/Community/VoVEGAVOProc It is likely that a substantial part of NCH effort next week would go the same way; but it is important to get the resource request correct especially in the light of CDR comments. NCH asked the meeting about how everyone felt things were progressing, and how we're looking against the current plan for May with regard to the next monthly report. PMW emphasised the need to keep up momentum and show good progress at the next report. Hardware: NCH reported no progress (owing to VDFS proposal work). However brief discussions with JNTD as to the way forward with loan kit have come up with the test plan for the next week or two: i) Ultra320 channel saturation tests; ii) SW RAID5 loading tests (worry is that running SW RAID5 under high write-IO load may be too slow). NCH reported that we can retain the loaned IBM kit for another month; plan is to try the hardware ServeRAID adapter with the high-spec disks supplied by eclipse. HMG reported that the existing cosaxp6 RAID server has been reconfigured to make space for intermediate SSA files. NCH asked about the implications of WSA 1 Gbit/s local area network in C1 - HMG will look in to this with ETWS, JNTD and HME. ACTION: HMG to look into implications of the current WSA LAN design in C1 in case of any unforseen difficulties. Networking: ETWS reported no progress on networking this week as we're waiting for the Cmabridge end to install GridFTP for testing (everything is ready at this end). Condor has been installed for test purposes on new server eyrie; ETWS is awaiting instructions from Ben Panter on use of condor and will then communicate with IAB on tests of pixel task distributed processing: "The beowulf cluster has got a second entrance called eyrie.roe.ac.uk and it is possible to log in directly via ssh. In the moment the users etws, bdp, and condor have access. From eyrie (the former node n004 of wiglaf) the nodes n003, n005, n006, and n007 are visible. This will be the testing area for all who would like to have a go with Condor. The setup of Condor will be done by Ben Panter." Software: User interface: MAR has been unavoidably delayed in Jersey, so nothing to report this week; IAB has been working 100% on the software architecture design document: "Work on the Software Architecture Document is progressing being mindfull of the need for the effort in making sure the document is as clear as possible and advances as soon as possible. Following discussions with nch and etws, a more streamlined module design has been been made." ACTION: IAB to produce second iteration on SADD by Wed am (28th May). NCH asked if ETWS could take forward revision of the existing WSA schema scripts. ACTION: ETWS (under guidance from NCH) to press forward with revision of WSA V1 schema scripts. SSA: As mentioned above, 1 Tbyte of holding space is now available for dump-out of SSA intermediate files for SQL Server. Production of intermediate files is now only awaiting the final results from Amos' junk detection algorithms, and the new galaxy scale calibration in UKI field 1 from JAP. ACTION: NCH to chase up Amos on the status of the final runs on the SSS data on IBM's bluedwarf machine. Miscellaneous: NCH reported that he will be attending a UKIDSS observing strategy meeting in London on the 28th; issues relevant to WSA will be discussed. ACTION: NCH to type up and circulate these minutes DONM: 10am, Friday 30th May, plate library.
