Update</span></h3>
<p>David reported that the next project at NERSC, a
monitoring run on the Spring 2018 data got underway
today. We are interested in how many jobs we can get
running simultaneously. He will be running 10 files per
run this time. Merging of the results will be done after
the files are brought back to the lab. This is version
17 in the line of monitoring launches.

<p>Mark described a new version of the script to build
private versions of Hall D software. The script formerly
known as my_sim-recon_jlab.sh is now
my_halld_build_jlab. There are new user options, among
them the ability to build only a selected set of
packages. See the documentation on the <a
