Hi
Just upgraded my machine to Win 7 x64 and installed Boinc 6.10.43 and everthing seemed to be working ok. But once a GPU (cuda23) has finished it does not start crunching the next WU instead it downloads another 7 WUs. I've currently got about 42 cuda23 with a status of "Ready to Start" I can restart the machine and it will complete one GPU task and then download another 7 units... Any Ideas?? Message log below

Thanks

Perhaps there's not enough GPU memory available after some tasks, until a reboot clears it again. To see if that's the case, you could enable <cpu_sched_debug> logging (with cc_config.xml).

I'm getting the same error on a WinXP 32bit box. Sometimes it will download, but most of the time it backs off with an HTTP error.

That is not the same error, unless your CUDA tasks don't start either after downloading.

You are correct. I saw the HTTP error in the log and made an assumption. Mea Culpa!

Hi, sorry about the slow reply.
I've turned on the <cpu_sched_debug> (see log below) but not sure what it is telling me? When you say GPU memory do you mean my graphics card memory (Which is now 512mb) I've set my Colour Depth to "medium 16 bit" and the cuda WU's will keep running ok. But I don't really want to do that as media centre whinges... I've just upgrade my machine to a 512mb card from a 256mb card that use to run the cuda WU's ok. I'm just a bit confused as to what is going on and how I can free up some memory? Also is it a bug in the code that keeps downloading the cuda WU's when it runs out of memory as I have over 100 to crunch now.

Thanks

I've turned on the <cpu_sched_debug> (see log below) but not sure what it is telling me.

It should be telling you needed versus available GPU memory, but in the meantime, the developers have changed that to <coproc_debug>. [edit]You should enable both logging options if you still suspect problems.[/edit]

When you say GPU memory do you mean my graphics card memory (Which is now 512mb)?

Yes, since GPU stands for Graphics Processing Unit. ;-)

I've set my Colour Depth to "medium 16 bit" and the cuda WU's will keep running ok. But I don't really want to do that as media centre whinges... I've just upgrade my machine to a 512mb card from a 256mb card that use to run the cuda WU's ok. I'm just a bit confused as to what is going on and how I can free up some memory?

Since you now have more total memory (reported), I don't think it's necessary to free up even more.

Also is it a bug in the code that keeps downloading the cuda WU's when it runs out of memory as I have over 100 to crunch now.

Yes, that's a bug, which is currently addressed by the developers.
