[Halla12_software] SoLID Software Meeting on Thursday at 2pm 03/26 Room-B101

A few reactions:

- Weighted generators are problematic for some studies. They distort
distributions of secondaries. Uniform generators should be available.

- Information needed to replicate a run could be either in the output file
or in an unambiguous, immutable other location — or a combination of both.
As was pointed out in the meeting, we might not want to write e.g. field
maps to every output file. But neither do we want to have the field map in
a database table that any user can later delete or modify. Some kind of
database to which users can add information, but not delete or modify it,
would be preferred, I think, for "standard" configurations, and then
deviations from standard configurations, as well as run options etc.
(command line and gcard, in GEMC terms), ought to be in the output file
itself.

- We should consider carefully, if there is a centralized database, how to
make and use local mirrors. At times the JLab connection is interrupted and
offsite work comes to a halt if the complete, up to date database
information is not available locally.

(Our database needs remind me of a version control system. Add new
information, but old information is preserved; central repository and local
copies; etc.)

- We should talk about installation. My experience has been that installing
GEMC offsite, with its long list of dependencies, has almost every time
been plagued with difficulties. Remoll was easy. What design decisions can
be made to minimize installation headaches?

- We need to think more about what data we want in the output and how to
organize it.
