DON'T ADD ANYTHING TO HERE. USE THE TASKBASE INSTEAD.
|
|
|
|
File upload handler should check for disk full,
|
|
return transient error, alert admins
|
|
If there are no active tasks, should start downloading
|
|
only the files for a particular result (avoid idle CPU)
|
|
Scheduler: don't send results whose deadlines will be missed.
|
|
This must take into account:
|
|
- pending work on host
|
|
- speed of host
|
|
- active fraction of host
|
|
- network speed of host
|
|
- results already in reply
|
|
Web site:
|
|
show mean, stddev of stats of active hosts
|
|
show max potential cobblestones (and percentage achieved)
|
|
Web site:
|
|
show table of size, MD5 of all executable files
|
|
break down by platform
|
|
Each RPC should contain a list of projects the host is attached to,
|
|
and their resource shares
|
|
Add field to user for the above list
|
|
Show above info on the web site
|
|
Implement coprocessor stuff (see platform.html)
|
|
add platform_details field to client state file
|
|
pass it in to every app
|
|
app can modify it if it wants
|
|
send back platform_details field with RPC
|
|
store in host table (and in result? make new host if it changes?)
|
|
add disk_avail field to host
|
|
send in RPC
|
|
use this in scheduling
|
|
Make sure "update prefs" works even if suspended
|
|
In GUI, show "suspended" on tasks and transfers if suspended
|
|
Clarify once and for all messages and other logs on Windows;
|
|
policy for truncating log files?
|
|

-----------------------
|
|
BUGS (arranged from high to low priority)
|
|
-----------------------
|
|
|
|
- reset/quit
|
|
- Resetting project should delete old project files
|
|
|
|
-----------------------
|
|
HIGH-PRIORITY (should do for beta test)
|
|
-----------------------
|
|
|
|
|
|
HTTP stuff
|
|
test HTTP redirect mechanism for all types of ops
|
|
finish SOCKS implementation, test
|
|
use HTTP 1.1
|
|
test w/ Apache 2.x
|
|
|
|
|
|
-----------------------
|
|
THINGS TO TEST (preferably with test scripts)
|
|
-----------------------
|
|
server stuff
|
|
implement server watchdogs
|
|
|
|
Add project w/ bad URL or account ID should report error
|
|
test this on Win, UNIX
|
|
|
|
backend stuff
|
|
- result reissue
|
|
(timeout_check should eventually create new results)
|
|
- WU failure: too many errors
|
|
- WU failure: too many good results
|
|
- credit is granted even if result arrives very late
|
|
|
|
- shared memory and CPU time measurement, with and without the BOINC API
|
|
- ensure cpu time doesn't reset if app is killed rather than quitting
|
|
- CPU accounting in the presence of checkpoint/restart
|
|
|
|
Platform-specific stuff
|
|
- timezone on all platforms
|
|
- make get_local_ip_addr() work in all cases
|
|
|
|
per-WU limits
|
|
abort result if any file exceeds max_nbytes
|
|
max disk
|
|
max CPU
|
|
max VM size
|
|
abort app if excess memory used
|
|
|
|
Windows screensaver functionality
|
|
idle-only behavior without screensaver - test
|
|
|
|
-----------------------
|
|
MEDIUM-PRIORITY (should do before public release)
|
|
-----------------------
|
|
|
|
add an RPC to verify an account ID (returns DB ID for user)
|
|
needed for multi-project stats sites
|
|
|
|
implement a "fetch prefs" command (regular RPC w/o work request)
|
|
|
|
all RPCs should return a "user-specific project URL"
|
|
to be used in GUI (might refer to user page)
|
|
|
|
in GUI, project name should hyperlink to a project-specified URL
|
|
(typically user page for that project)
|
|
|
|
let user choose language files in installation process
|
|
|
|
write general language file manipulation functions
|
|
|
|
use https to secure login pages, do we care about authenticator
|
|
being transmitted without encryption from the client?
|
|
|
|
write docs for project management
|
|
how to start/stop server complex
|
|
what needs to be backed up and how
|
|
|
|
account creation: show privacy/usage policies
|
|
|
|
decide what to do with invalid result files in upload directory
|
|
|
|
think about sh_fopen related functionality in BOINC client
|
|
|
|
Implement FIFO mechanism in scheduler for results that can't be sent
|
|
|
|
user profiles on web (borrow logic from SETI@home)
|
|
|
|
Devise system for porting applications
|
|
password-protected web-based interface for
|
|
uploading app versions and adding them to DB
|
|
XXX should do this manually since need to sign
|
|
|
|
Add 2-D waterfall display to Astropulse
|
|
|
|
Deadline mechanism for results
|
|
- use in result dispatching
|
|
- use in file uploading (decide what to upload next)
|
|
- use in deciding when to make scheduler RPC (done already?)
|
|
|
|
Testing framework
|
|
better mechanisms to model server/client/communication failure
|
|
better mechanisms to simulate large load
|
|
do client/server on separate hosts?
|
|
|
|
CPU benchmarking
|
|
review CPU benchmarks - do they do what we want?
|
|
what to do when tests show hardware problem?
|
|
How should we weight factors for credit?
|
|
run CPU tests unobtrusively, periodically
|
|
check that on/conn/active fracs are maintainted correctly
|
|
check that bandwidth is measured correctly
|
|
measure disk/mem size on all platforms
|
|
get timezone to work
|
|
|
|
Redundancy checking and validation
|
|
test the validation mechanism
|
|
make sure credit is granted correctly
|
|
make sure average, total credit maintained correctly for user, host
|
|
|
|
Scheduler
|
|
Should dispatch results based on deadline?
|
|
test that scheduler estimates WU completion time correctly
|
|
test that scheduler sends right amount of work
|
|
test that client estimates remaining work correctly,
|
|
requests correct # of seconds
|
|
test that hi/low water mark system works
|
|
test that scheduler sends only feasible WUs
|
|
|
|
Scheduler RPC
|
|
formalize notion of "permanent failure" (e.g. can't download file)
|
|
report perm failures to scheduler, record in DB
|
|
make sure RPC backoff is done for any perm failure
|
|
(in general, should never make back-to-back RPCs to a project)
|
|
make sure that client eventually reloads master URL
|
|
|
|
Application graphics
|
|
finish design, implementation, doc, testing
|
|
size, frame rate, whether to generate
|
|
|
|
Work generation
|
|
generation of upload signature is very slow
|
|
|
|
Add batch features to ops web
|
|
|
|
The Windows installer sometimes leave boinc.# files in the BOINC
|
|
directory. This is likely due to the installer not being able to
|
|
delete the old boinc.dll file
|
|
|
|
If a client connects to the scheduling server using default prefs,
|
|
use the stored user prefs for determining how much work to send
|
|
|
|
get preferences works, but is slightly confusing - you have to go to
|
|
projects, right click on "get preferences", and then exit/restart boinc
|
|
before I get to see my new pretty underwater colors.
|
|
|
|
"suspend" seems to suspend, but after restart the CPU time jumped up
|
|
by a significant amount. This is because Windows 9x uses GetTickCount
|
|
for CPU time.
|
|
|
|
"Retry transfers now" feature, especially for dialup users
|
|
|
|
-----------------------
|
|
LONG-TERM IDEAS AND PROJECTS
|
|
-----------------------
|
|
|
|
CPU benchmarking
|
|
This should be done by a pseudo-application
|
|
rather than by the core client.
|
|
This would eliminate the GUI-starvation problem,
|
|
and would make it possible to have architecture-specific
|
|
benchmarking programs (e.g. for graphics coprocessor)
|
|
or project-specific programs.
|
|
|
|
investigate binary diff mechanism for updating persistent files
|
|
|
|
verify support for > 4 GB files everywhere
|
|
|
|
Local scheduling
|
|
more intelligent decision about when/what to work on
|
|
- monitor VM situation, run small-footprint programs
|
|
even if user active
|
|
- monitor network usage, do net xfers if network idle
|
|
even if user active
|
|
|
|
The following would require client to accept connections:
|
|
- clients can act as proxy scheduling server
|
|
- exiting client can pass work to another client
|
|
- client can transfer files to other clients
|
|
|
|
User/host "reputation"
|
|
keep track of % results bad, %results claimed > 2x granted credit
|
|
both per-host and per-user.
|
|
Make these visible to project, to that user (only)
|
|
|
|
Storage validation
|
|
periodic rehash of persistent files;
|
|
compare results between hosts
|
|
|
|
WU/result sequence mechanism
|
|
design/implement/document
|
|
|
|
Multiple application files
|
|
document, test
|
|
|
|
Versioning
|
|
think through issues involved in:
|
|
compatibility of core client and scheduling server
|
|
compatibility of core client and data server
|
|
compatibility of core client and app version
|
|
compatibility of core client and client state file?
|
|
Need version numbers for protocols/interfaces?
|
|
What messages to show user? Project?
|
|
|
|
Persistent files
|
|
test
|
|
design/implement test reporting, retrieval mechanisms
|
|
(do this using WU/results with null application?)
|
|
|
|
NET_XFER_SET
|
|
review logic; prevent one stream for starving others
|
