Change all the PHP code to use _mysql_query() instead of mysql_query()
(and similar for other functions).
_mysql_query() uses the mysqli API if available, else the old API.
Going forward, all PHP code should the DB abstration layer if possible;
else it should use the _mysql_* functions.
On some hosts, gpu_active_frac may be much less than active_frac
(i.e., GPUs may be available much less than CPUs).
Use gpu_active_frac in the following places:
- scheduler: in estimating the elapsed time of jobs,
to decide whether they can meet deadline
- scheduler: in computing the effective speed of a (host, app version),
when deciding what size class it belongs to
- size_census: in computing effective speed of (host, app versions)
(Previously, we were just using active_frac in all these cases)
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
