Dear Offline folks,
Chip and I had a discussion this morning about what is an acceptable 
scope and schedule for data challenge tests of your analysis frameworks. 
The definitive tests should be done at JLab using the systems on which 
the final analysis will be done, i.e. the ENP analysis cluster (Farm). 
The suggested scope and schedule is based upon the dates that you have 
given for the first major bumps in computing requirements, 5000 cores 
for GLUEX in Q2 of 2015 and 2400 for CLAS12 in Q2 of 2016:

  * 10% of final scale 24 months in advance.
  * 25% of final scale 18 months in advance.
  * 50% of final scale 12 months in advance.

Each test should last for 2-4 days depending upon how many problems are 
encountered. The larger scale tests will require significant resources 
which Chip proposes that he will loan to us from the LQCD clusters so as 
not to significantly disturb other Farm users. He proposes moving the 
resources to us on a Monday then moving them back to LQCD on a Friday 
giving us up to four work days for testing.

I spoke with Mark this morning and he agreed that this is a reasonable 
schedule and that GLUEX have already met the 24 month test requirement. 
However the 25% scale test will be due in the next few months.

Chip and I both think that this is a reasonable schedule and not 
difficult to meet. We would like you to consider it as you prepare 
presentations for the review.

Regards to all,
Graham
