BOINC 6.6.11 is out. As stated in other threads this is a Development version. The change log is below.

6.6.11

- client: if a project is at max backoff for a resource, stop accumulating debt if it's at or around zero.

This prevents other projects from being driven unboundedly negative.

- client: if the number of overworked projects exceeds the number of device instances, clear debts; this indicates that an earlier client was buggy and produced bad debt values.

- client: new work-fetch policy:

1) if an instance is idle, get work from highest-debt project, even if it's overworked.

2) if resource has a shortfall, get work from highest-debt non-overworked project

3) if there's a fetchable non-overworked project with no runnable jobs, get from the highest-debt one
(each step is done first for GPU, then CPU)

Clause 3) is new.

It will cause the client to get jobs for as many projects as possible, even if there is no shortfall. This is necessary to make the notion of "overworked" meaningful (otherwise, any project with long jobs can become overworked). It also maintains as much variety as possible (like pre-6.6 clients).

Also (small bug fix) if a project is overworked for resource R, request work for R only in case 1).

- client: remove the "debt repair" mechanism added earlier today.

There are situations where multiple projects can legitimately have large negative LTD on a uniprocessor. Instead...

- client: add <zero_debts> option to cc_config.xml

- client: fix bug that can cause no GPU jobs to be scheduled even when a GPU is free

- client: tweak the LTD calculation so that the largest debt always tends towards zero

- client: print message if downloaded file has wrong size

- client: associate file xfer messages with a project; fixes #848

- client: more instances of showing project with message. Fixes #848

- client: fix work-fetch bug that caused infinite fetch; cleanup/reorganization of work fetch logic

- client: work-fetch bug fix: if we're fetching work for a starved project, it most have no runnable jobs for ANY resource.

- client: work-fetch bug fix: when setting requests in the shortfall case, don't request anything if project is backed off or overworked for the resource.

- scheduler: include driver version in the CUDA description string storing in the database;

- WINSCR: Fix the BOINC text displayed is the screensaver control panel applet

- WINSCR: Get rid of the 'Up to 5 second wait' for the data thread to terminate. Force terminate the thread and clean up the graphics app in a clean-up routine. Forcing the user to wait when they return to the system isn't a good idea.

- WINSCR: Fix screensaver issue where the screensaver locks up when the graphics application deadlocks for one reason or another.

- WINSCR: Clean-up some of the thread cleanup logic.

Please do not post only problems, but also successful observations of 6.6.11. A lot of people talk about problems, but no one about success.

Got it installed on 1 machine at the moment. Doesn't appear to have any problems, but I need to retest a few things that were broken in earlier 6.6 builds. Work-fetch issues usually take a couple of days of running to come out.
