  2. 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….

  3. 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

  4. 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”)

  5. Software on Beamlines • Software is being made available through the ‘module’ system • Data processing packages available include: • Mosflm • XDS • HKL2000 • D*trek being investigated

  6. 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

  7. 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.

  8. 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)

  9. 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.

  10. 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?
