Projects will need to update DB and recompile all back-end programs.
Summary:
- new way of computing credit
- "reliable host" mechanism is per app version
- "host punishment" mechanism is per app version
- adjustment of wu.rsc_fpops_est provides the
equivalent of per app version DCF
- max jobs in progress is now per app
- max jobs per RPC is now per app
TODO:
- reliable mechanism:
- populate and use host_app_version.error_rate
- populate host_app_version.turnaround
- host punishment:
- populate host_app_version.max_jobs_per_day
- populate host_app_version.n_jobs_today
- use app.max_jobs_per_day_init
- job limits:
- use app.max_jobs_in_progress, max_gpu_jobs_in_progress
- use app.max_jobs_per_rpc
- adjust wu.rsc_fpops_est
- remove old credit stuff
fpops_cumulative, credit_multiplier
credit computation in scheduler
- AVERAGE class: use the Knuth algorithm (Wikipedia)
svn path=/trunk/boinc/; revision=21021
- scheduler: fix bug in adaptive replication:
if send an unreplicated job to untrusted host,
set both wu.target_nresults and wu.min_quorum to app.target_nresults.
svn path=/trunk/boinc/; revision=15762
(attempt to send big jobs to fast hosts, small jobs to slow hosts).
- have "census" compute mean/stdev of host speeds,
write it to a file perf_info.txt
- have feeder compute mean/stdev of sizes of jobs in shmem
- have feeder read perf_info.txt into shmem
- scheduler: add some debugging messages for app version selection
- Add LGPL license to a few files
- upgrade/setup scripts: copy census to bin/
svn path=/trunk/boinc/; revision=15136
to allow validator to assign different credit
to different instances of a job
- Scheduler: if can't open DB, return <project_is_down/>
(fixes#578)
- clean up logic of modify_claimed_credit
- feeder: for -priority_order_create_time, use workunitid
rather than create time (faster for the DB)
