I don't know if someone has already asked this question, so: is there any plan for a gpu application?

Source code is very enlarged, so it will take a lot of time to create this type of app. And writing a CUDA program is slightly different from writing a CPU app.

Source code is not (yet) open, so it's impossible to help the development.

P.S. OpenCl is preferable, 'cause it runs on all hw.

Small update

After this weekend is possibility that we start testing GPU app :)

Great!!
What we have to do? Is universe@home test site online?

First test I will do myself obviously. After it I will add GPU application as "test" and it will be available only for persons who mark test applications in their settings.
Especially on first revisions it will be very unstable as GPU coding is completely new area for us, so advice to use it only by volunteers who can accept risk of crashes...

After this tests we will see how it's going and decide about next steps...

Will the GPU app being doing the same type of work as the CPU app (only faster), or will it being doing different things entirely?

Same job but more deeply (bigger precision).

We still work on it but have some problems with results accuracy...

If I may offer a suggestion, if it is a question of AMD vs. Nvidia, then just choose one and go with it. Sometimes (very too often) projects bend over backwards to be compatible with everyone, and that compromises the science, or at least the development. It would be much better to have either brand of GPU than no GPU at all.

This is why we work on OpenCL :)
But, the problem isn't in compatibility (at the moment) but in result accuracy...

We will continue the fight until we get app working ;)

Sorry, cannot find a checkbox for testapps.
My settings simply say run all applications.

I also prefer OpenCL apps; if it runs as fine as on Einstein this would be one of the real great projects!

At the moment we haven't released GPU app (even for testers) as we still working on it. The process going very slowly as algorithm never was predicted to work on GPU's.

As soon as we get in working more or less properly I will publish info about it.

I would also be interested in running a GPU application.

I send positive thoughts.

Yes, it did ;)

But we still not finish yet GPU version...
