Terameeting of Dec. 16th 2008. Present: Yannick, Henry, Mathias M., Fred, Greg, Patrick

Yannick's summary document

T0005

 T0005: Jean-francois Sygnet has given us comments on CFHTLS release and documents; Yannick added these comments and did corrections when necessary. There are still some Sygnet' suggestions missing.
 There are still documents which are incorrect concerning T0005 on the web pages; Yannick has asked Henry to once again double-check these pages.

Megacam PI data

 Hudson data: Megacam data ready to be distributed; waiting to see if he needs the weight-maps.
 Simona Mei would like to have the latest NGVS stacks.

Wircam PI

 Flagley data is diffuse nebular data without any "off" pattern; this will be difficult to reduce.
 Suggestion from Yannick: it would be a good idea if PIs contact terapix BEFORE observations are planned to discuss the best possible observing strategy to avoid these kinds of problems. (Can Jean-Charles put this info on the terapix web pages?

Discussion of role de Yuliana at TERAPIX

 Yuliana will process PI-Hudson data and will work with Greg and Mathias on the development of youpi (end-user testing).

Youpi development

 Shopping cart works, Scamp works and the rest works.
 QF processing policy now works. Can make a scamp for example just on the machine with the largest amount of ram.
 QF for all deep images and all wide images currently in process
 Youpi demo with QualityFITS policies.
 Mathias raises questions about the performance of youpi with many accesses
 Question about managing scamp with many threads and vm; there should be a possibility to specify how many threads each process takes so as not to take all cores in a given machine.

 Swarp will be the next plug-in to be developed.

Hardware

 All the new machines have arrived including the 9U fileserver.
 mix14,mix15,mix16 processors have been replaced. mix3 motherboard.
 mix7 raid card for sure HS; Fred will try return this card, but this could mean that the RAID array is unavailable for some time.
 Fred will make some tests with distributed file systems on these new machines.
 mix21 will need to moved so the 9U file storage system can be installed; Fred will tell us when this happens.
 A home has been found for cos1,cos2,cos3 and cos4 (obsolete terapix machines).

 Fred will remove mix* machines from public ip-address and make them only accessible from the private network. The additional free public ip addresses will be put into the DHCP pool.

 Fred will try install 2MASS locally to avoid problems of network access to CDS.

Other matters

 Not clear if R is what we need for a pipeline environment. Can mathias make a quantitative assessment of what the utility of R is for pipeline processing?

 Yuliana's computer has been set up and she has account on the terapix computers and also will receive mails from teraops and teralist.

 Everyone will send dates of Xmas vacations to teralist

MERRY CHRISTMAS to everyone!!... next meeting After January 5
