- Add a different method to run and WUs on the CPU: don't switch between project every xx minutes, just put all WUs on a single list separating projects with a horizontal line but run the WUs of all projects indistinctly.

You think "switching between projects every X minutes" is all BOINC does? The CPU scheduler is one of the most complex parts of the client.

What are the project deadlines?

When it says "connect to the Internet every N days", set a realistic value. If you're offline for 7 days, set 7 days. Setting it too high may mean getting less work, because it may think that if you're going to be offline for too long, you won't be able to return the work in time for the deadline.

I had hoped it would be a Wiki entry, which I could edit - but it's a web php page, which I can't.

It has now been moved to the wiki: http://boinc.berkeley.edu/wiki/GPU_computing

That's particularly strange because "172.16.58.217" is not a hostname that has to be resolved... What's the master URL defined in config.xml?

As far as I can tell, BOINC 6.10.21 is only a 32-bit app in the first place. It's my understanding that 64-bit apps will give you the option of launching in 32-bit mode. i.e. Do a GET INFO on Safari on your 64-bit Mac OS 10.6.x - notice the option check-box for 32-bit mode? With BOINC, you have no such option, which, according to Apple Dev Notes means it's a 32-bit app.

The BOINC application you see in /Applications is the manager, which is a universal binary with only PowerPC and 32-bit Intel.

Inside, it contains a universal version of the BOINC client, in PowerPC, 32-bit Intel, and 64-bit Intel.

Are there any known people who have gotten their mac boinc client to recognize their GPUs on Mac OS 10.6.2?

Not until 64-bit CUDA libraries for Mac are available, which there aren't, last thing I heard.

To get rid of the debt resetting if a project runs out of work. Debt should rise to a maximum amount -> say 172800 seconds (2 days). Why 2 days? Why not.

Putting such a low limit defeats the whole point of having debt at all. If your computer runs CPDN in deadline-panic-mode for 6 months, CPDN shouldn't run for 6 months to let the other projects catch up. (I'm assuming equal resource shares here)

Fair enough, but the issue is if BOINC doesn't have any wu's cached, asks for new work, then receives none as a project is out of work then the debt is reset to 0. This is not desirable is my point.

Well, I have to admit that I don't understand debts anymore since they added GPU support and changed how the scheduler works.

Is it (hypothetically) possible? It it is, that's option that can be integrated to BOINC manager.

That option was added few years ago, but it needs server changes. SZTAKI hasn't upgraded their server for years.

My videocard is NVIDIA, not ATI. And it does not support CUDA. So these messages seem strange a bit. Maybe something is wrong?

Your video cards are detected when the client runs, not when you compile it. That would be silly. Support for both ATI and NVIDIA is always compiled.

Imagine getting a new card and having to recompile the client from source...

I dont know why some are running versions as old as 6.5.x

I'm using 6.2 because I have no intention to use my GPU for crunching, and I don't want all the new bugs that were introduced along with GPU support.

if I have this code for example:

for(int i0=0;i0<1000;i0++)
{
do_computation();
}

and i want to divide this work to four workunits or tasks (each one 250 iter), how i determine that to server???

That's not how it works. It's your job to divide it in parts. For example:
int main(int argc, char** argv) {
    /* somehow parse the command line from argv to get the initial value */
    for(int i=0; i<100; i++) {
        int x = i+initial;
        do_computation(x);
    }
}

Then you create ten workunits, giving in the command line the initial values 0, 100, 200, 300, 400, etc.

as per: http://boinc.berkeley.edu/trac/wiki/CompileClient#BuildingtheclientwithVisualStudio2008andVisualStudio2008ExpressEdition.
Got about 15 errors.

You don't need to build the client, only the libraries.

A startup delay timer that is "settable" by the user (minimum of zero, maximum of 120 or 180 seconds) to allow a delay before boinc launches any tasks.

This would allow other tasks to get started before all available "spare" cycles are taken up by tasks and allow Windows to get "less busy" before BOINC's tasks go active.

Already supported since BOINC 6.1.6. You have to add <start_delay>180</start_delay> to cc_config.xml.

See http://boinc.berkeley.edu/wiki/Cc_config.xml#Options

Thanks Richard,

I am using GridRepublic manager and had to unconnect the manager and was able to detach a project. Using the account manager again, the project I removed came back! I guess I would have to stop using the account manager and manage the projects myself.

You have to go to GridRepublic website and detach it from there.

If is it possible to edit Manager to work with some project for X sec and wait/sleep Y sec, I would like to try to edit the source code and force it to work that way. It seems like possible solution.

That's what it's doing already.
