Re: what does 'ready to report' mean

Ok, I've read both of Rom's attempts to dazzle with a lot of gobblygook and fancy footwork and I don't think immediate reporting costs would be all that expensive. What's the difference between reporting after transmission, and thousands of users forcing reporting by clicking on Update? Not much in my opinion... biggrin I'm half tempted to forego half the points and use cruncher3's BOINC version. He had the foresight to see the value of reporting immediately to avoid possible loss of result s credits due to any of several possible gliches.

Thanks again for all your help...

Re: what does 'ready to report' mean

There are so many x-audit controls at the Server end and the clients, that a loss of a part of the file send or received is next to absolutely negligible. If u can find posts here, that report point losses due transmission failures, I'd be obliged. That is not to say it does not happen, but at almost 61 million completed results to date, it is here.

Re: what does 'ready to report' mean

It's not impossible, because it has happene to me. I have lost credits due to weather changes affecting my satellite connection and reports being launched off to the great bit bucket in the sky... Those will and do show in "My Grid" as "Not Reported". As I said before, there are numerous possible problems the "could" arise that has the potential of lost credits. biggrin Thanks again for your comments.

Re: what does 'ready to report' mean

Split reporting does not affect network traffic significantly, the big difference is database access. The report is only a few bytes, this data would have to be passed back and forth anyway. You can see exactly how much by looking in your BOINC directory for scheduler request and scheduler reply files. Opening and closing the database is the largest part of the report, so if you can report multiple tasks in one database access it can dramatically reduce server overhead.

Re: what does 'ready to report' mean

when i used ud, the agent sent a result as soon as it was finished.

so what does this boinc thing mean? another unit has been running for 15 minutes already.

i set network communication at .1 days, and under activity i checked 'always run/always available.'


I see this subject has been brought back again. Can anyone recommend what one business PC running 24/7 should have for network communcations?

I believe that I am using the default ...
.01 days.

As I post this, I notice only one work unit being shown. Before a Boinc feeder went down a couple of days ago, I could see two work units. Once being crunched and the other waiting to be crunched.

Currently, my work unit shown will be completed in 1 hour and 20 minutes.

I am still waiting for the second work unit to be downloaded.

Thanks for any suggestions. wink

Re: what does 'ready to report' mean

The default is actually 0.1 days - 2.4 hours. This is fine for an always-on Internet connection.

If you have an unreliable connection, you might want to increase it to 0.5 days (12 hours) - a setting which can easily survive any minor blip or outage.

People on dialup should adjust the setting according to their dialling habits. 2 days is about the limit for what is practical. Beyond that, things may get messy.

There's no real reason for reducing the setting below 0.1.

Re: what does 'ready to report' mean

Johnny Cool,

The BOiNC scheduler is slow to adapt to quick WU's and quick to adapt to slow work units, a protection mechanism to prevent overcommitment. If a work unit is nearing completion, BOiNC calculates forward and sees if enough work is there, which is primary. Even if your schedule is set to 1 day, BOiNC would pull new work before the current WU is finished.

It is essential to not change the settings every other day. Some of the statistical tuning takes weeks to settle. Anyway, I've withstood the itch to interfere and I'm always crunching. The Sunday case was a bad rare exception.... WCG has an uptime of > 99.8%.

The 'Ready To Report' (part 2 of a Result reporting cycle) will happen... often before the next WU is requested, but if your buffer is set to 1 day it will take much longer than 0.1 days..... likely just before it pulls the next batch of work. The unofficial BOiNC wiki explains in detail.

Note, that because we have 8 hour FAAH, 2 hour HDC, 1.25 hour GC and 3 Hour HPF2, its very difficult for BOiNC to settle fully. Do only one type like FAAH or GC and it will become very constant....eventually when it realizes u e.g. only do GC, it will pull enough work to cover the 0.1 days or 1.0 days or whatever buffer size u set.

cheers

Re: what does 'ready to report' mean

Hi Sekerob... you're almost right. BOINC work units include a size estimate on a per-work-unit basis. There were some serious issues with duration estimation when WCG set these badly (the same for HPF and FAAH). They have fixed that ages ago, and hopefully they have estimated GC well, too. BOINC uses the DCF, the estimated length and the benchmark to estimate the duration of a work unit.

Complicated...

Re: what does 'ready to report' mean

okay, for the overkill.... the DCF correct's the Total Time to Completion projection of all the WU's in the buffer. If the DCF is going from 1 to 1.1 the TTC's get increased for all WU's by 10 percent, but when a fast one comes thru the reduction is much less than the increase.... it's all to prevent not meeting deadlines. My box has been learning of the 10 or so GC's and the projections are now very close to the actual achieved times.

Anyway, too much detail for most who want to just switch it on, 'set and forget' and truly approach it from the idle cycle view.
