- client: make GPU enumeration warnings more consistent
(e.g., "NVIDIA" instead of "CUDA").
- scheduler: get rid of ati13 plan class.
Require 1.4+ driver for plan class ati.

and <ati_backoff> elements to scheduler reply.
These specify backoffs for the resource types,
overriding the existing backoff mechanism.
Projects can supply these if they don't have apps of a particular type
and don't want to get periodic requests for them.

start only enough jobs to fill CPUs per project,
not all the CPU jobs at once.
I'm not sure how much difference this makes,
but this is how it's supposed to work.
- client: if app_info.xml doesn't specify flops,
use an estimate that takes GPUs into account.
- client: if it's been more than 2 weeks since time stats update,
don't decay on_frac at all.

is running a graphics application.
Change the semantics of the "don't use GPU while computer in use" pref
to "don't use a GPU that's running a graphics app while
computer is in use".
This will increase GPU utilization on multi-GPU systems.

make sure they're the same (i.e., enforce file immutability).
TODO: do this for input files too
- client: check return values from CUDA device detection functions

e.g. the Milkyway@home ATI app, of which we can typically run
2 or 3 instances at once on a GPU.
Changes include:
- In APP_VERSION, don't use a COPROCS to represent the GPU
requirements; just use doubles ncudas and natis.
- sufficient_coprocs() etc. are no longer members of COPROCS
- in HOST_USAGE, ncudas and natis are doubles
- in scheduler request, req_instances is now a double
This checkin doesn't include the job scheduling logic,
i.e. assigning jobs to GPUs. That will follow.

don't modify user preferences or CPID.
- client: fix bug that shows ATI version incorrectly
- database: host.posts has been repurposed as a salt (or seqno)
for a new type of weak authenticator that won't depend on password
- web code:
modify forum_preferences.posts instead of host.posts.
(actually, the former isn't used either, we just do a select count(*);
should fix this at some point).

for showing how GPU instances are being reserved
- scheduler: add "sse3" plan class example
- web: add option (NO_TEAMS constant) for suppressing teams

After finding the "most capable" GPU,
ignore FLOPS in deciding what GPUs are equivalent to it.
This opens up the possibility that the client will get jobs
that it won't be able to finish in time.
But it still avoids getting jobs that will crash.
svn path=/trunk/boinc/; revision=17875
old: find fastest GPU, and pretend that others are the same.
Problem: other GPUs might be less capable,
and not able to handle jobs sent by server.
new: find the most "capable" GPU, use others that are equivalent,
don't use those that are not.
"Capable" is defined by
- compute capability (i.e., hardware version)
- driver version
- memory size
- FLOPs
in that priority order.
See comments in lib/coproc.h
svn path=/trunk/boinc/; revision=17855
(say what kind of job and why we're scheduling it)
- client: log messages describing GPUs: one line per GPU; fixes#879
svn path=/trunk/boinc/; revision=17847
(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
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.
