Dear Collaborators,

The first part of the first full reconstruction launch over this year’s 
data (2017-01 ver01) is complete. It comprises all 234 production runs 
between 30274 and 30788, before we increased the beam current and hence 
the trigger rate. The launch was running for about 20 days, but the Jlab 
Scientific Computing group reported at least 2 incidents during this 
time which slowed down the processing. The integrated CPU time was 1.6Mh 
(or 180a). 33 out of 22965 (0.14%) data files could not be processed due 
to a problem in the tracking. We will start the second half later today 
with updated software.

All REST files (22,932 files, 63TB) are pinned to the cache disk for the 
next 60 days:

The histograms and efficiency trees can be found here:

A subfolder with merged histograms and trees is included in each folder.

The results are also visible on the usual monitoring web-pages:


Details of the launch analysis can be found here:


Best regards,
