JLab Farm Mini Data Challenge
Mark gave a snapshot of the current mini challenge. See his wiki page for details.
- The current set of jobs has been able to saturate the Hall D share of the farm, which is only about 4% at this point.
- Most of the analysis jobs (HD_ROOT) crashed due to the self-declared memory limit of 2 GB. Paul Mattione has checked in an option to cut-off reconstruction of high multiplicity events. This may help.
- One of the next steps is to produce output data in REST format.
