1) Questions and Answers : Windows : LONG time between work unit downloads... (Message 37866)

If you are seeing your client request work, but none is downloaded, and the message says there was work, but your machine doesn't have enough memory, then that is the topic discussed at length here and here. In short, things should have improved now, and any such message should be pretty rare.

If your machine is not requesting xxxx seconds of new work when it connects to Rosetta, or is just NOT connecting to Rosetta, then this requires an explaination of how the BOINC scheduler works. With that many projects, your BOINC scheduler has it's "hands full" trying to figure out how to schedule your machine's time. This topic is discussed further here in this QA item.

I think between these three references, your questions should be addressed. But if not, please post questions to one of those existing threads, or a new one in the Number Crunching message board.

Q: Why won't BOINC download more Rosetta Work units?

A: It is possible the servers are down for some reason (quite rare). You should check the server status.

But it is more likely you are seeing a message in the BOINC Manager saying "...not requesting new work". If so, then your PC is actually not asking for more work.

If you are running multiple BOINC projects, the BOINC manager plans out what will be crunched next, and balances goals like the deadlines of the work units, and your preferences as to resource share to devote to each project. In this balancing act, it sometimes crunches a project more than it's normal share in order to meet a deadline. When this occurs, the project being crunched incurs a "debt" to the other projects. BOINC will take this debt in to account when requesting new work. It is not uncommon, especially when running 3 or more projects, for BOINC to decide to crunch other projects for a period of a day or two in order to pay back such debts. And so during that time it will not order more work for projects that it does not plan to be crunching for a while.

In the end, if you leave things alone and resist the temptation to try and FORCE BOINC to do work for a specific project, it will work itself back in to balance and again download work for each project.

If you want to increase the resource share for Rosetta, you can increase the value in your Rosetta preferences, and then update to the project. You can view the present resource share in the Projects tab of the BOINC manager. The BOINC Wiki has more discussion of how resource share works.

Rosetta, of the seven different programs BOINC is running, does not download new work units to start either after current work units have been completed and reported. Nor does the program download new work units to start on just prior to the current work unit completing its task. Is there a problem, a solution, or is it something that can be worked on by Rosetta staff for correction in the future?


What is your "Connect to network about every" setting in General preferences?

It had been set to make a connection every .1 days. I've gone back and read other posts which seemed to suggest increasing the connection time to get more work, (I did so)but I would expect doing that will only serve to lengthen time between connections; not solve the problem. With it having been set so frequently before, I would have expected it to connect and download as the others do; ie: just before they run out of work, they've connected and downloaded the next work unit to be done. It frequently goes eight or ten hours before connecting and downloading Rosetta. Since I posted the inquiry, it just downloaded work about a half hour ago.

There have been instances of when seven of the eight programs running will exhaust work units and nothing new downloads until it had run out of work entirely for single program running in BOINC and twice in the past year when the only thing that would get the program to take on new work was to detach from everything, delete BOINC and reinstall from scratch. However, deleting the old BOINC program and installing the most current version appears to have stopped the problem of no work for anything whatsoever.

So, my inquiry at present: Are others frequently experiencing slow downloads from Rosetta (6 - 12 hrs. of nothing at all before new work arrives) for no obvious reason such as a comment noted in the 'message' section of BOINC that there is work but that it exceeds memory available, or that there is no work to be obtained.
