GPU option

It might just be me, but when I run the updated CharityEngine App it never uses more than 10% of my GPU. Is this a bug or will more WUs in the future make the usage go up? I have a NVidia graphics card.

Upcoming work will make better use of GPUs (*especially Nvidia) -- stay tuned.

I've got an existing BOINC 7.0.64 manager that runs Charity Engine and a few other projects, and I've opted in to run Beta test applications in my settings.

Q: As per your recent email, do I HAVE to download the latest version of Charity Engine application, or will the BOINC manager make use of any GPU accelerated applications from CE automatically?

I don't really want to stop my other projects.

Anything v7+ should be ok -- so you don't need to update from your BOINC v7.0.64 if you don't want to.

currently, we do not have an application that is making use of your GTX 470 card very well right now - but like Matt says, this is going to change very soon (probably early in the week).


one of your hosts (a laptop) only has an Intel GPU card, which sadly is not supported at this point and will not receive tasks for it. Another host might have a supported card, but you have to reinstall BOINC and disable "protected application execution" within the installer as that prevents use of GPU applications - or you can simply install the latest Charity Engine client. You can still keep running your other projects even with this setting - but please note that they will not give you any jackpot points.

Talking about GPU WUs.

Would it be possible to increase the number of WUs we can get or to increase drastically the time they take until they complete?

I have a crossfire of 7970 (2 radeon HD 7970). BOINC pull 2 work units, crunch them simultaneously and send them alsmot simultaneously, but fails, sometimes, to request new WUs which leave my GPUs hungry until one of my CPU task get sent and boinc request new work.

Do you have any other suggestion to solve this issue?

I have increased limits on server and you should now get 4 tasks at once. Please let me know if it solves your issue.
