Discharged - projector booked ACTION: NJC, NCH, ETWS (with invites to RGM and JAP) to meet on Tuesday 15th 2pm Plate Library to have a photometric recalibration brain storming session. Discharged; NJC is progressing with analysis and design for CU8. Actions partly discharged but continuing: ----------------------------------------- ACTION: MAR & NCH to check out SQL Server networked server functionality for cross-server querying. Continues; NCH suggested we should do some experiments with the linked SQL Servers ahmose & amenhotep once the dust has settled on their reorganisation over the next couple of weeks. ACTION: ETWS to put (or link) ACD's network document on the WSA TWiki. Continues: (still) awaiting the finished article from ACD. - all continuing; thanks for progressing these. Actions carried forward from 11/02/05 meeting: ---------------------------------------------- None this week. Specific points and new actions: -------------------------------- Project management: NCH described the plans for VDUC, and showed the team his presentation. Some discussions ensued about emphasis on operations and datamining; NCH agreed to add in a slide covering these points. NCH noted that the Rolling Grant review, which includes review of the case for resources for archive operations and a datamining scientist, takes place in Cambridge next Wednesday. PMW, NCH and RGM will attend and make presentations. WFCAM update: Nothing new this week. Comments and issues arising from CASU fortnightly minutes: No new minutes this week. Networking: Processed phase-I commissioning data has been received from CASU (thanks to JRL), and image data have been ingested. Some issues remain to be cleared up: NCH/ETWS will discuss with CASU by email and face-to-face next Monday. Hardware: Online archive hardware continues to function normally. Some problems with offline servers are still being investigated. NCH noted that the new flat-file storage system "sneferu" is now installed in the cabinets, and needs to be configured. ACTION: ETWS to submit a helpdesk to get IT Support (i.e. HME) to set up new server "sneferu" with a single account scos and it's 3 RAID arrays NFS exported to djoser and thoth. Software: NCH reported no progress this week due to work on UKIDSS MSB preparation. ETWS has been testing out ingest; NJC working on photometric recalibration; MAR on the WSA browsing interfaces and user access implementation with JDT (see below). SSA: No news this week. Astrogrid deployment: JDT reported stress testing of the AstroGrid community software - a note has been put up on the AG Wiki at http://wiki.astrogrid.org/bin/view/Astrogrid/JDTStressesTheCommunity which has also been linked from the WSA TWiki pages. Some discussion ensued concerning scalability etc., and it seems that a single physical server cannot cope with so many different community DBs (this is something the infrastructure software was never really meant to do - the idea was always to have distributed physical servers with one community DB on each). It was agreed that setting up the communities should progress anyway, while MAR sets up an ad-hoc solution based around the community concept. NCH noted that the current list details about 35 separate communities with a handful of people in each (mainly institute-based). Miscellaneous: Nothing else this week.
