Good day,

My finished WU's would not upload due to "HTTP error".
Any workaround?

Cheers

What I don't have the resources to do is to distribute the fix to - what was it at the last count - 800,211 users worldwide.

But as they are not experiencing the problem, then they don't the fix.

But Igor experienced the problem. Martin experienced the problem. Heck, last week I managed to download an 8 month SETI work cache on two machines!

So that means there are 800,208 people that don't appear to be experienceing the problem. As you are one of the 3, that means you only need to distribute it to 2 other people at this stage.
Compared to 800,000 or so, 2 doesn't sound like that much of a big deal to me.


What I did was to change the default of (0.1 days) for the "Connect to network about every" parameter to (0.2 days). The result I got is that the BOINC manager immediately downloaded the entire daily quota. However, I expected it would load 2 WU's instead of 1 as it usually does.

It was reproducible with 2 versions of the client, including 5.4.11, 2 different computers, 2 OS's and 4 projects.

I think the algorithm that does the calculation in the client is the issue. Should be something simple, like integers instead of floating point.

This should be fixed, as it causes a lot of extra load on the servers and the processing is slowed down due to those WU's that only wait for their deadline to expire.

Well, I installed 5.6.5, and it does not reproduce the problem. I presume it has been fixed. ;-)

Hi,

The other day I tried to change the default setting of "Connect to network about every" "0.1 days" in "General Preferences" to something else; this caused the BOINC manager to immediately load a total number of work units equal to "Maximum daily WU quota per CPU", which was "100/day" or something similar, depending on the computer and the project.

This is an obvious error, because:
1) There is no way my computer could process that many WU's before the deadline;
2) I could not discover any obvious way to change the value of the "Maximum daily WU quota per CPU" parameter.

I noticed that I'm not the only one to have this problem, which causes a lot of extra unnecessary internet traffic and eventually slows down the processing.

I hope someone will look at this issue, which should be common to all the projects that use BOINC framework.

Cheers,
Igor

Several days ago boinc stopped to receive work from seti@home. I suspect this is due to the introduction of the ADVANCED version, as Einstein is working, and boinc on a second computer is OK too. What should I do?
