A quick update from my last post...
Seti did indeed release the long-awaited multi-beam v7 app. This is causing a bit of confusion on what to do to upgrade, if at all.
If you don't use an app_info then you don't need to do anything. The project will simply supply the apps itself. As you can imagine there are a lot of people trying to download them now so a lot of downloads are backing off.
The CPU and OpenCL apps are not yet available from a 3rd party site. The "stock" apps are your best option for now. I would suggest you finish off any multi-beam work you have, upload and report it. After that rename app_info.xml, restart BOINC and let it get the "stock" apps. Even better if you can delay this for as long as possible due to the load on the download server.
They too release their BRP5 work units that are much larger than the BRP4 work units. As there are no optimised apps for Einstein it should simply update itself and start work. I have managed to process a few work units already on my machine with dual GTX660 cards.
