Upgrade problem fixed - FYI

I have 3 computers which I upgraded from BOINC 5.4.11 to 5.10.13. Two of them encountered no problems, but the third, my work laptop would not download work orders. In the Transfers tab, everything just said "Download Pending."
My job let me install BOINC on the laptop, but wouldn't let me use their bandwidth to up- or download anything, so I have it get 10 days worth of work (which is really 5 with dual cores), work all week, then bring it home and let it upload the results on the weekend.
With BOINC 5.4.11, I had overridden the settings from BOINCstats with a cc_config.xml file. BOINC 5.10.13 doesn't seem to like that file. Once I removed cc_config.xml, the agent downloaded new work orders.
Just in case anyone else encounters this type of problem.

Re: Upgrade problem fixed - FYI

Hi garoob.

Thanks for that. As for the cc_config.xml, i think that is one multiplier parm that worked in prior versions has been disabled in the newer versions. 5.10 has now the "additional buffer" option in the local preferences. Be though aware that they do not work proper, not even in 5.10.18 which i think got worse instead of better.... latest discovery: enter project switching at 480 minutes as in 480.00 minutes and it will switch every 480 seconds.... its a little messy.

cheers

Re: Upgrade problem fixed - FYI

garoob,
The fact that you can see only 5 days of work is not because you have a dual-core machine. If you had a single core you would see half of them! The reason is due to the way Boinc integrates your connection rate and the deadlines of the jobs for evaluating how many WUs it can stack without missing deadlines. To make it a little more complex (you are allowed to read it "unpredictable") this algorithm is not the same in all versions of Boinc. The practical bottom line is that you will hardly ever get more than 5 days of work in Boinc's queue for WCG projects. So if you are already getting that much you are already at your best!

Cheers. Jean.

Re: Upgrade problem fixed - FYI

JmBoullier - Actually, I don't have a problem with number of work orders in queue. For example, I have 84 work orders right now, which should be about 7 days worth of work. That's enough to keep it going while I'm at work. I didn't know that the algorithms that calculate that differ! Thanks for that!

Sekerob - Did the documentation for 5.10.13 say that cc_config.xml didn't work in that version? Because I didn't read it anyway! Sounds like they may need another new version to fix stuff soon. I like having the local preferences GUI rather than cc_config, though.

Re: Upgrade problem fixed - FYI

It's undocumented and only found out thru asking. The cc_config.xml is still very much valid in itself. Use it all the time and it should be there to control the level of messaging detail you get. Maybe you have it malformed somehow.

Here's a good sample with the iimmobilized line struck-out.
<cc_config>
<log_flags>
<checkpoint_debug>1</checkpoint_debug>
<cpu_sched>1</cpu_sched>
<file_xfer>1</file_xfer>
<sched_ops>1</sched_ops>
<task>1</task>
<cpu_sched_debug>0</cpu_sched_debug>
<rr_simulation>0</rr_simulation>
<debt_debug>0</debt_debug>
<task_debug>0</task_debug>
<work_fetch_debug>0</work_fetch_debug>
<unparsed_xml>0</unparsed_xml>
<state_debug>0</state_debug>
<file_xfer_debug>0</file_xfer_debug>
<sched_op_debug>0</sched_op_debug>
<http_debug>0</http_debug>
<proxy_debug>0</proxy_debug>
<time_debug>0</time_debug>
<http_xfer_debug>0</http_xfer_debug>
<poll_debug>0</poll_debug>
<guirpc_debug>0</guirpc_debug>
<scrsave_debug>0</scrsave_debug>
<app_msg_send>0</app_msg_send>
<app_msg_receive>0</app_msg_receive>
<mem_usage_debug>0</mem_usage_debug>
<network_status_debug>0</network_status_debug>
</log_flags>
<options>
<work_request_factor>0.5</work_request_factor>
<save_stats_days>90</save_stats_days>
</options>
</cc_config>


With the Additional Buffer of 5.10.x you can get real maximum 10 days worth of work in the buffer. Just set connect to 1.0 days (default WCG 0.3, default BOINC 0.1) and additional buffer from 1.00 to 10.00 days (WCG has no default yet, BOINC default is 0.25 days). What you will find if you stretch the value toward the max, your client will run continuously in "running, high priority" (5.10.x series only message). Not recommended to do unless you really need it. The lengths of work are highly variable. Just uploaded FAAH jobs from 1 client that varied from 4:25 to 7:20 hours. BOINC continuously adjust it's estimations on last work completed for a project. Suggest you visit the various wikis out there for elaborations. They are not up to snuff with latest scheduler logic, so just take it as a broad line informational.
