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.

There are two mechanisms to prevent the scheduler from
sending jobs that won't finish by their deadline.
Simple mechanism:
The client sends the interval x for which CPUs are projected
to be saturated.
Given a job with estimated duration y,
the scheduler doesn't send it if x + y exceeds the delay bound.
If it does send it, x is incremented by y.
Complex mechanism:
Client sends workload description.
Scheduler does EDF simulation, sees if deadlines are missed.
The only project using this AFAIK is BOINC alpha test.
Neither of these mechanisms takes coprocessors into account,
and as a result jobs could be sent that are doomed to
miss their deadline.
This checkin adds coprocessor awareness to the Simple mechanism.
Changes:
Client:
compute estimated delay (i.e. time until non-saturation)
for coprocessors as well as CPU.
Send them in scheduler request as part of coproc descriptor.
Scheduler:
Keep track of estimated delays separately for different resources
- client: fixed bug that computed CPU estimated delay incorrectly
- client: the work request (req_secs) for a resource is the min
of the project's share and the shortfall.

- client: restore notion of overworked;
if a project is overworked for a resource R,
don't fetch work for R unless there are idle instances

but we don't need to send any more CUDA jobs,
delete the BEST_APP_VERSION record and look for another app version.
This lets the scheduler send both CUDA and CPU app versions
for a given app in a single RPC.

1) net adjustment for eligible projects is zero;
2) max LTD is zero
- scheduler: fix msgs so disk size is shown in GB

and add <cuda_multiplier>.
The latter is used in calculating max jobs/day for a host;
namely, it's host.max_results_day * (NCPUS + NCUDA*cuda_multiplier).
Set it to 10 or so if you have CUDA apps.
- scheduler: don't overload effective_ncpus();
instead, add two new functions,
max_results_day_multiplier() and max_wus_in_progress_multiplier()
- scheduler: don't reduce max_results_day if we get an aborted job
(it might have been aborted by the project;
not appopriate to punish host in this case)
svn path=/trunk/boinc/; revision=16959
- Update to libtool 1.5.24
- build environment: Major automake changes that I've been warning about
for some time.
- Now uses libtool to build libraries.
- Builds separate boinc_fcgi and sched_fcgi libraries for use with
FCGI server components.
- New macro "BOINC_CHECK_LIB_WITH" that executes a "AC_CHECK_LIB" on
a library only if --with-libname[=DIR] is specified on the configure
command line. This is to allow inclusion of libraries when the
ssl, gtk, wxWidgets, or other configuration is incorrect for static
libraries.
- Added a lot of "--with-*" for some libraries that might be required for
static builds.
- The sea directory has been moved to packages/generic. Changes to sea
and the associated scripts might be required to better make use of the
staging mechanism and shared libraries.
- Fixed includes of boinc_fcgi.h in many files.
- Fixed places where FCGI_FILE needs to be used implicitly.
- Fixed missing define of _SC_PAGESIZE on hosts that define only
_SC_PAGE_SIZE.
- Moved build of boinc_cmd (and source file) from lib to client
svn path=/trunk/boinc/; revision=16904
- parse new request message elements
(CPU and coproc requested seconds and instances)
- decide how many jobs to send based on these params
- select app version based on these params
(may send both CPU and CUDA app versions for the same app!)

exceptional cases (e.g., send at least one job to a host with no work)

for the selected APP_VERSION, rather than on the CPU benchmarks.
Otherwise estimates are wrong for GPU or multi-thread apps.
- scheduler: start switching from having SCHED_REQUEST and
SCHED_REPLY as globals instead of passing them around as args;
to be continued.
svn path=/trunk/boinc/; revision=16691
- scheduler: fix egregious bug where wu_is_infeasible_fast() result
is ignored, and we send jobs to hosts that can't handle them.
- scheduler: don't check for disk space in work_needed();
do it in check_disk(), which generates a message to user.
- scheduler: add -debug_log flag, which sends stderr to
"debug_log" rather than scheduler_log.txt (for debugging)
