status
Status
  • 3 beamlines with users, 1 starting commissioning.
  • datasets > 20 images
    • 2007 - 856 total
    • 2008 – 521 (first 3 months despite problems!)
  • Total data = 5.5Tb some compressed some not….
directory structure
Directory structure
  • Data is stored in /dls/$BEAMLINE/data/$YEAR/”proposal-visit”:
    • Where proposal is proposal number and visit is session on any beamline
    • Read-only* for backup and archive reasons
  • Subdirectories of “proposal-visit” created automatically:
    • spool : used by other beamlines
    • *processing: writeable area to be used for processing data by user (no quota)
    • jpegs: contains jpeg and thumbnails of all images
    • $HOME: quota enabled areas
    • Other subdirectories can be created by the user through GDA
  • Future directories
    • processed: will contain results from any processing software automatically run by diamond
    • jpegs of the crystal and loop from the inline viewing system will need to be stored
archiving progress
Archiving Progress
  • ISPyB
    • Testing of GDA automatically writing to ISPyB underway
    • DNA ISPyB integration still to do but should be based on work already done
  • CBF
    • Archive of CBF (ImgCIF) or Vendor data format yet to be decided
    • Reliable migration/conversion tools now available
  • Data backup and remote access
    • Testing is underway for automatic archive of data onto tape and download from data portal. (Project currently subject to delays due to STFC “changes”)
software on beamlines
Software on Beamlines
  • Software is being made available through the ‘module’ system
  • Data processing packages available include:
    • Mosflm
    • XDS
    • HKL2000
    • D*trek being investigated
automated data collection
Automated Data Collection
  • DNA
    • Version 1.1 of DNA has been successfully tested on I03 in ‘manual’ mode
    • This has not been made available to users or tested on I02 and I04
  • EDNA
    • Diamond is currently committed to EDNA as a successor to DNA
automated data processing
Automated data processing
  • On datasets with >20 images, testing is underway to use a cluster to:
    • Process the data using XIA2 in both 2D (Mosflm) and 3D (XDS). (thanks to G. Winter)
  • Other packages e.g. ELVES are being investigated. Suggestions welcome.
cluster environment for ccp4
Cluster environment for CCP4?

Classic Cluster

  • 24 dual dual core nodes
  • Sun Grid Engine
  • Future replacement

NVIDIA Tesla

  • Massively multithreaded SIMD Architecture.
    • Thousands of threads required for efficiency
  • Per £3500 1U rack mount unit
    • ≈ 400 times the calculation performance of a single core Intel processor (optimized external to DLS, Financial Monte Carlo)
    • 40 times the performance for data heavy analysis (relatively unoptimized internal DLS code, tomographic reconstruction)
multi user shared environment and ccp4
Multi user shared environment and CCP4
  • Automatic updates
    • Software managers mailing list? Monolithic releases are nice but…. Users don’t have permissions….
  • Old CCP4i
    • No shared projects – future looks good though
  • Permissions problems?
    • Coot-backup
  • No coherent plan for exploiting high performance computing?
  • But as there are ‘resources’ at a large site it is possible within certain constraints.
ccp4 and diamond
CCP4 and Diamond
  • Diamond does not do much with CCP4 and CCP4 does not do much with Diamond
    • Some exceptions mostly in data processing.
  • Areas we could do more together
    • General software developments (parallelisation, tools, testing, releases….)
      • Some information exchange both ways.
    • Technique developments and automation.
    • Vehicle to the users through their data.
  • But can anyone be bothered?
