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

- AVERAGE class: use the Knuth algorithm (Wikipedia)

10000*major + 100*minor + release,
rather than 100*major + minor.
Sometimes you need release-level resolution.
This affects:
- app_version.min_core_version
- config: min_core_client_version_announced
- config: min_core_client_version
Projects using these must multiply them by 100.

- remove obsolete and buggy code from transitioner (create_result() in backend_lib)
- account for 'mixed' scheduling in explain_to_user() in sched_send.cpp
- finish transition to configurable patterns for distinguishing files reported by the client
in the Einstein@home-specific part of send_work_locality in sched_locality
(removed previous hardcoded strcmps)

to accept CPU, NVIDIA and ATI jobs.
These prefs are shown only where relevant:
e.g., only for processor types for which the project has app versions,
and if it has versions for only one type, no pref is shown.
These prefs affect both client and scheduler.
The client won't ask for work for a device blocked by prefs,
and the scheduler won't send it.
This replaces earlier optional project-specific prefs for
"no CPU jobs" and "no GPU jobs".
(However, these prefs continue to be honored on the server side).
- client: if NVIDIA driver is unknown, say that rather than 0
svn path=/trunk/boinc/; revision=19194
elapsed_time: the elapsed time (runtime) as reported by client
flops_estimate: the app's estimated FLOPS as reported by app_plan()
app_version_id: the DB ID of the app_version used
(or -1 if anonymous platform)
TODO: show these in the web interfaces,
and use them where appropriate

Old:
1) check deadline based on wu.delay_bound
2) in add_result_to_reply(), potentially modify wu.delay_bound,
e.g. because of retry acceleration
problem: reducing delay bound may cause deadline miss
New:
1) new function get_delay_bound_range()
(called from wu_is_infeasible_fast())
returns optimistic and pessimistic delay bounds.
Retry acceleration logic is here.
2) check deadline based on optimistic bound;
if that fails, check based on pessimistic bound.
Set wu.delay_bound to the one that worked.
Notes:
- get_delay_bound_range() needs result priority and report deadline,
and it's called before we read the full result.
So add these items to WORK_ITEM and WU_RESULT.
- get_delay_bound_range() could be customized for
project-specific deadline policy.
- add_result_to_reply() was becoming a toxic waste dump.
Deadline-related stuff should have been factored out in any case.

feature without requiring use of score-based scheduling.
So add a new customizable function, wu_is_infeasible_custom(),
where projects can put job-specific checks.
Also, move customizable functions (of which there are now 4)
to a new file, sched_customize.cpp.

The limit on jobs in progress is now
max_wus_in_progress * NCPUS
+ max_wus_in_progress * NGPUS
where NCPUS and NGPUS reflect prefs and are capped.
Furthermore: if the client reports plan class for in-progress jobs
(see checkin of 31 May 2009)
then these limits are enforced separately;
i.e. the # of in-progress CPU jobs is <= max_wus_in_progress*NCPUS,
and the # of in-progress GPU jobs is <= max_wus_in_progress_gpu*NGPUS
- scheduler config: rename <cuda_multiplier> to <gpu_multiplier>
- scheduler: <max_wus_to_send> is now scaled by
(NCPUS + gpu_multiplier*NGPUS)
- scheduler: don't keep scanning array if !work_needed()
- scheduler: moved array-scan logic from sched_send.cpp to sched_array.cpp
- scheduler: don't say "no work available" if jobs are available
but work_needed() is initially false

Useful if you're mixing locality and regular scheduling.

(app versions don't have a <coprocs> around coproc elements,
may an oversight but let's stick with it).
Anyway, I think it's working now.
- lib: remove "owner" array from COPROC.
This was used in client to keep track of assignment of
coprocessors to tasks, but we got rid of the reserve/free scheme.
NOTE: this breaks the mechanism for passing --device N to apps;
I'll have to do this another way. Stay tuned.
svn path=/trunk/boinc/; revision=17543
Old: although the request message contained all info
about the app version (flops, coproc usage etc.)
the server ignored this info,
and assumed that all anonymous platform apps where CPU.
With 6.6 client, this could produce infinite work fetch:
- client uses anon platform, has coproc app
- client has idle CPU, requests CPU work
- scheduler sends it jobs, thinking they will be done by CPU app
- client asks for more work etc.
New: scheduler parses full info on anon platform app versions:
plan class, FLOPS, coprocs.
It uses this info to make scheduling decisions;
in particular, if the request is for CUDA work,
if will only send jobs that use a CUDA app version.
The <result> records it returns contain info
(plan_class) that tells the client which app_version to use.
This will work correctly even if the client has multiple app versions
for the same app (e.g., a CPU version and a GPU version)

when to do a scheduler RPC:
if user request or acct mgr request, ignore backoff and suspend via GUI;
in all other cases honor both of these.
svn path=/trunk/boinc/; revision=17504
which of those files to include
- Modified MAC address check to work on some non-Linux unixes.
(mac_address.cpp)
- Added suggested change to "already attached to project" checking.
(ProjectInfoPage.cpp)
- changed includes of standard c header files to their c++ equivalents
(i.e. replaced <stdio.h> with <cstdio>) for namespace protection.
- replaced "using namespace std;" with more explicit "using std::function" in
several files.
- Fixed bug in checking whether the os is OS/2 and added conditional OS_OS2
to the build environment. (boinc_platform.m4,configure.ac)
- Changed build environment to not use -nostandardlibs unless we are using
G++ and static linkage is specified. (configure.ac)
- Added makefiles and package building files for solaris CSW package manager.
- Fixed bug with attempting to find login name using logname. (configure.ac)
- Added ifdef HAVE_* protection around some include files commonly found in
sys.
- Added support for unified binary for x86_64/i686-pc-solaris.
(cs_platforms.cpp)
- generate_host_cpid() now uses MAC address on non-linux unix.
(hostinfo_network.cpp)
- Macro BOINC_SET_COMPILE_FLAGS now doesn't check gcc only flags on non-gcc
compilers. (boinc_set_compile_flags.m4)
- Library compiles no longer depend upon the library extension or require
the library to be prefixed with lib.
- More fixes for fcgi builds.
- Added declaration of "struct ether_addr" and ether_ntoa(). Have not yet
implemented ether_ntoa() for machines that don't have it, or where it is
buggy. (unix_util.h)
- Added FCGI::perror() which calls FCGI_perror(). (boinc_fcgi.{h,cpp})
- Fixed library Makefiles so that all required headers get installed.
