See http://boinc.berkeley.edu/trac/wiki/MultiSize
The components of this include:
- DB changes:
add size_class to workunit and result
n_size_classes to app; >1 means multi-size
- size_regulator daemon program: change results states
from INACTIVE to UNSENT carefully
- size_census program; writes quantile info in flat files
- transitioner: when creating results for multi-size apps,
set server state to INACTIVE
- sched shmem (feeder): read quantile info from flat files,
store in shared memory
- scheduler (score-based scheduling): for multi-size apps,
add component to score function for size class.
- show_shmem: show result size class
- make_work (and other callers of count_unsent_results()):
count both INACTIVE and UNSENT
- create_work: add --size_class cmdline option
Also:
- if get MySQL errors in upgrade, don't rewrite db_version
