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.

- Added translation awareness to view_profile.php
- Added translation awareness to show_user.php
- Added cacheability to the community_links() by splitting it into a function for getting the cacheable object "get_community_links_object()" and another for displaying it "community_links()"
- Added the community_links cacheable object to the cache in show_user.php
- Changed view_profile.php from being full-page cached to using data caching. Only the community_links object is cached as that is the only one containing heavy queries. All other queries are simple and will be cached at the SQL query cache level.

- web: check whether to show profile in separate function
from displaying profile; eliminate double headers
- scheduler: finish purge of redundant arguments

put a textual summary of them in host.serialnum (currently unused)
- web: show coprocs on host detail page
- db_dump: include coproc info in host XML

- add a "forgot email address?" link
- change text to say that the authenticator method can be used
in case of forgotten email OR forgotten password
- if bad password on login, show them the login form again
(with email field populated)
instead of a harsh failure message
- if bad email on login, show login form again instead of harsh message
- update authenticator method instructions
with new BOINC data directory paths
