wish to use it.
- The script calculate_credit_multiplier (expected to be run daily as
a config.xml task) looks at the ratio of granted credit to CPU time
for recent results for each app. Multiplier is calculated to cause
median hosts granted credit per cpu second to equal to equal that
expected from its benchmarks. This is 30-day exponentially averaged
with the previous value of the multplier and stored in the table
credit_multplier.
- When a result is received the server adjusts claimed credit by the
value the multiplier had when the result was sent.

and change the correspending structure field from 64KB to 256KB
(could increase this if needed).
This is needed to handle app versions with lots (> 100) of files
- change LARGE_BLOB_SIZE to BLOB_SIZE a bunch of places
- Change COPROCS from vector<COPROC> to vector<COPROC*>.
Otherwise the right virtual functions of COPROCs don't get called

- update_versions: use __ (not :) as separator for plan class
- client: add plan_class to APP_VERSION;
an app version is now identified by platform/version/plan_class
- client CPU scheduler: don't assume apps use 1 CPU
- client: add avg_ncpus, max_cpus, flops, cmdline to RESULT
- scheduler: implement app planning scheme
Other changes:
- client: if symlink() fails, make a XML soft link instead
(for Unix running off a FAT32 FS)
- client: don't accept nonpositive resource share from AMS
- daemons and DB: check for error returns from enumerations,
and exit if so. Thus, if the MySQL server goes down,
all the daemons will soon exit.
The cron script will restart them every 5 min,
so when the DB server comes back up so will the project.
- web: show empty max CPU % as ---
- API: get rid of all_threads_cpu_time option (always the case now)
svn path=/trunk/boinc/; revision=14966
and apps that use coprocessors.
There now can be several app_versions for the same
(app, platform, version_num) combination.
This changes a number of things.
- Added app_version.plan_class field to DB
- update_versions now looks for a :plan-class in the
file or directory name, and puts it in the app_version's DB record
- Change uniqueness constraint to include plan_class
- Feeder: the feeder was putting non-deprecated app_versions
in shared mem, and leaving it to the scheduler to
find the latest version for a given platform.
This is dumb.
Instead, for each app/platform pair the feeder now
finds the highest version number of a non-deprecated app version,
and enumerates all non-deprecated app_versions with that
app/platform/version
- Scheduler: add a BEST_APP_VERSION data structure that keeps track,
for each app, what the best app_version is for this host.
This saves the work of recomputing it for each job.
svn path=/trunk/boinc/; revision=14906
The design has been changed to constant #threads per app version
Various changes from Kevin Reed/WCG:
- server: add workunit.rsc_bandwidth_bound: if nonzero,
send this WU only to hosts with that much download bandwidth
- assimilators: if a handler returns DEFER_ASSIMILATION,
the WU remains in INIT state and will be handled when the
next instance completes.
Useful if you want the assimilator to see all instances.
- scheduler: when setting result.outcome = DETACHED,
set received_time to now
- scheduler: removed the reliable_time and reliable_min_avg_credit
options
- scheduler/web: add optional <allow_non_preferred_projects>
in project preferences.
If present, user will accept work from non-selected apps
if no work is available for selected apps
- scheduler: improved messages for projects with multiple apps
- scheduler: added config options
<granted_credit_weight> and <granted_credit_ramp_up>.
Used in calculating host.claimed_credit_per_cpu_sec,
but I'm not sure how.
- Added two new credit-granting formulas (validate_util.C):
stddev_credit() and two_credit()
- server DB: add rollback_transaction() and affected_rows() to DB_CONN
NOTE: DB update required

But if we do, set their transitioner time to plus infinity
so that we don't see them again.
(otherwise we go into an infinite loop)
- DB code: remove "high_priority" from queries not from scheduler
(should probably remove them from there too)
- file_deleter: print error msg if apache user doesn't exist

Lets you assign a WU to a particular host,
to one or all hosts belonging to a user or team, or to all hosts.
See http://boinc.berkeley.edu/trac/wiki/AssignedWork
Disabled unless you include <enable_assignment> in config.xml
Uses a new DB table.
Tested but only a little.
- Server: code cleanup; moved result-handling to a new file,
and removed the PLATFORM_LIST arg to everything
(put it in SCHEDULER_REQUEST instead)

on successive calls, scans through ALL the sendable
jobs satisfying the select clause
(it does this by ID order, so there's no order clause)
This is used for HR, so that if a job has been committed
to an HR class, we eventually get it.
With extremely minimal testing, the new HR stuff seems to work.

there is for each HR class, and writes it to a file.
This will be used soon for HR support in the feeder.
- split the HR code into hr.C,h (stuff used by both census and scheduler)
and sched_hr.C (stuff used only by the scheduler)
- database: change DB_CREDITED_JOB to treat workunitid
as a double (which it is) rather than a long.
BTW, long == int.
- fixed lots of compile warnings in the server code

which may modify an EXISTING & OVER result in the database.
file_upload_handler: check for 'stop_upload' trigger file in the
project root directory. If so, return ERR_TRANSIENT to hosts which
attempt uploads. This is the equivalent of 'stop_sched' for the
scheduler. (Eric, you may want to check that this is FCGI compatible).
