Multi OS folding

Post by Spazturtle »

Hi is wish to set folding up so that I have a windows partitions and a linux one, and they both work on the same WU so if I switch OS's it picks up where the other left off.

Basically can I have FAH run from the same directory in multiple OS's so that I can switch OS's and continue folding?

You'll have to run the Windows client under Wine when you're using your Linux partition. The Linux client can't process a WU downloaded by the Windows client, and vice versa.

Even under Wine I think you are going to have serious problems with bonus points. The two installs are going to be considered different by the work/collection servers and if a WU is returned by an install that did not get it originally you will not get bonus points. I do not know but I suspect that the WU will not be credited to the original install which means it will likely you will have difficulties maintaining the 80% successful return rate. Also the servers may try to reissue old previously returned WU's to the original install that was returned by the other OS.

To some extent it all depends on how much you use one OS over the other. If it is 99% in one, then there will not be a lot of WU's switching between the OS's. If it is 50-50 then you will kill off virtually all the bonus points. I wouldn't do it

I believe if you export the F@h registry key as described here and import it to Wine's registry, it should work. IIRC, I have received the QRB bonus this way (though it's been a while since I tested it). I made sure to use the same directory when folding on each OS by mounting the F@h directory as a Windows file system under the non-Windows OS (the WU was not moved to another directory as described in the sneakernetting web page).

Keep in mind that no one has figured out how to run v7 under Wine, so you're limited to folding with the Windows v6 client under both OSes.

Ah well most of the time my desktop is unused but I do use it for gaming sometimes, I had heard that running FAH on linux gets you 15% more points but it sounds like its not worth folding on two os's.

I could install a linux partition and fold on there and when I want to use windows switch to windows and load the linux partition in VMWare so it continues, then switch back when done.

If you're folding on Wine, you're not actually folding on Linux. There's a pretty high probability that your information about Linux getting more points is because you're running the Linux core rather than the Windows core (the same one that you'd be using on Windows and on Wine).
