Hi,

I have a laptop with dual boot... Win XP (on C:) and 2k3 (on E:)... I have boinc installed in both partitions, independently from each other.

Since I have been working lately in the office, so the work done has been from the w2k3 partition. When I go home and go into the wxp partition, all work units reported as 'expired' and so, I deleted them all and lost all those cpu time (and score!).

So, is there any way to have the project folder shared between partitions and opsys? I am even planning to install linux or solaris10 for i386 soon...

Regards,

Leo

Just install BOINC in the same directory for all the operating systems you use.
You can still lose work though, if you don't switch between the OSes often enough.

But if you just install BOINC for all OSes in e.g. C:\BOINC, then all will run from there.

Thanks! but my point was to not lose work... so, let's say I install boinc for the first time in wxp, under c:\boinc, attach all projects, run a few days...

then, I install w2k3 in e:, but I install boinc in the same c:\boinc...

will this second install recognize my previous work? I mean, will it add all my projects automagically, and will it start working after finishing the install process???

Or, shall it start blank, so I have to re-attach to all projects, and re-download new work, when I already have a lot half-way???

It won't recognize the work you are doing under the other OS, but the account_*.xml files should take care of your computer auto-attaching to all the projects. Just for each OS with its own host ID.

So your best course of work is to use a low connect to in your preferences and possibly, before you go switch OSes, put BOINC on No New Tasks and run the cache dry, upload & report. That way you won't lose work.

Don't rely on projects having cross-platform checkpoints!

Do you have (or could you make) a third 'data' partition visible to both OSs? Or are you saying that the same C:\BOINC folder is visible all the time, whichever OS is in control?

Provided you do have a single folder which is visible all the time, and both OSs are flavours of Windows, you should be able to install BOINC to the common repository from both OSs, and crunch the same WUs with the same apps in either mode. Wouldn't work for a Linux/Windows dual boot, though.

Thanks a lot for all your responses... it seems boinc manager is not yet ready to multiboot, although, I'd like to see that in an upcoming release.

In one of my previous laptop (a few years ago), I had seti@home installed three times (under winxp, win2k, and linux)... however, there was no "too late" warning with that program, so I could run any OS for a month, then the next one for another week, and so on, and never lose any work unit or score.

Maybe some admin here could put this feature into the wish list ????

at least for win flavors, it should be able, if installed in the same folder as an existing version, to recognize the existing projects AND work units and continue with those...

Projects set deadlines. They're not set by the BOINC core client.

Deadlines range from hours (some resends from PrimeGrid) to a year or more (CPDN).

One issue i can see with this is its going to be a lot of work. When i change Linux kernels it often decides its a new machine and i haven't lost work yet but expect i would and thats basically the same OS. Projects use different app for different OS's due to different things being supported by the different OS. Imagine someone trying to make the same science app do the same thing on Win98 and Vista. Everything would have to be dumbed down to 98 standards.
A lot of projects don't support more than the current 'doze platforms XP and some Vista so i cant see them making the app support 9x and Vista.
I know those are two very closely related Operating Systems yes but im certain things that worked on Vista don't always work on XP or the other way around otherwise you wouldn't need to dual boot anyway and this is the same problem thats going to go on with the science apps.
