Discussions
Hardware Acquisition
QServ
- (Jason) Any discussion/decision on the dbdev* hardware replacement(s)
- (Fritz) Consider that qserv developers want a 'playground' environment (ssd, nvme).
- (Jason) Can we wait until Skylake? Would like to give you Apache Pass + 6 memory channels to play with.
PDAC
Stripe82 Transfers (Igor Gaponenko)
- all coadds (FITS files) have been restored from IN2P3's iRODS and copied over to NCSA at: /datasets/gapon/data/DC_2013/coadd/deepCoadd
- ~55% of calexpes have been transfered from IN2P3 to NCSA so far. They're found at: /datasets/gapon/data/DC_2013/calexps/sci-results/
Note, this is a GPFS file system mounted on some nodes of PDAC.
- The stripe82 catalogs have been (some file are still being transferred from Nebula onto /datasets) partitioned and are ready to be loaded into PDAQ Qserv as soon as it will be available.
SUI
- Can we do builds on the machines (Xiuqin)
- Yes, just remember no DR is provided (Jason)
Qserv / Containerization
- Fabrice Jammes able to launch on 30 nights
- Working through env config issues with NCSA (quick turn around)
- Brian Van Klaveren working on containerized DAX services
- Working on that on the next 2 days. Waiting on work on dax01.
- Need docker (may yum install) will send request to NCSA
Calibration of single epoch exposures
- Necessary software/module/libraries not currently available on monolithic database, but could be easily deployed
Qserv / Dax services available next week to SUI team (very tentative)
- Qserv up, Brian hopeful on services
- Exposures to become available as they are transferred into /datasets
- Some Calexp exposures missing (~20%), Igor Gaponenko to research and report on what is missing.
- (gpdf) what happens when a calexp is accessed that is missing? Brian Van Klaveren imgsrv should return an error
