We could have put all in gpugrid, but this project is quite innovative and also we are practicing in the use of OpenCL and AMD/ATI.
It's a kind of beta project, and the name seemed appropriate. Furthermore, we would not want to stop and start gpugrid or mess with the server in the process of getting OpenCL working, the same way we are able to do here with just few users.Donate@home is fair on other BOINC projects as well. It is giving the right amount of credits (in fact a bit less) and it does not pay the volunteers, so it cannot out-compete on grounds which are not purely the will to participate.
The only reason to participate is the cause for which it is working, if the scientists are doing good science with the fund raised, as well as any other donation. The volunteer remains volunteer and decides only based on the quality of the science they are supporting.
A common question is. Is it for profit?
It is not for profit in the same way that a charity foundation is not for profit. It receives monetary donations like here, and it uses them for the given purpose. It is however different from other projects in that the results of the calculation instead of being only a cost as usual, also generate the donations. So you should consider this when you participate it.
