Hello,
----------------------------------------I have a dual boot PC with Windows 7 x64 and Windows XP x64. I use both of the operating systems depending on my work. If I install the BOINC client to both OS's, is it possible that both clients share the same data set during calculations. So that if I start to use XP and use it for one week, or for a few hours, for example, the jobs in Windows 7 will continue to be calculated in Windows XP and will not be time aborted. Thank you.

Hello sarachaneli,
I assume that the project software is the same for either Windows 7 or Windows XP, but I doubt that the 2 Managers will cooperate by running the same set of work units. Still, I have never tried it. Set your profile to only run 1 work unit, then try setting up BOINC to run in XP 64-bit and see if runs one of the work units from Windows 7. I expect it will not, but it never hurts to check Lawrence |

It "should" work but the client may get confused as to the machines identity since you'll have 2 seperate BOINC installations with different OS's and likely diffeent computer names reading from the same data directory. Try it out and see if it works.
Pick a convenient location for both the BOINC folder and BOINC data folder, then do a seperate BOINC client installation in each OS and point the installers to the same BOINC folders on the hard drive. |

Good luck with that arrangement. I tried that as a Windows 7 beta tester and the boot and password files became corrupted and I was not able to ever boot into XP again. I did report this to Microsoft and I I do not know if this situation was ever addressed especially since Windows 7 Professional has XP software emulation to run XP apps that may not work with Windows 7.

It has been my experience you can dual boot with Linux providing you install Windows first, then Linux. That order has worked best, however if you delete Linux from your hard drive, you will still have the Linux boot loader on your computer. That would need to be adjusted as well. |

PlatformX-PlatformX works fine (e.g. Windows XP-Vista/W7), long as both installs are pointed to same data_dir and the bits are same for science app, which is in WCGs case not a problem, presently ** ;o)
----------------------------------------PlatformX-PlatformY does not work (e.g. WindowsXP and Linux) for a number of reasons, one being the homogeneity rule. Different platforms (OS groups) produce slightly different results which would make them fail validation. Most importantly though the slots hold a copy of the science app, so that even an interim science upgrade such as CEP v 6.19 to CEP v 6.35 does not matter until a new task is started. Try starting the Windows Science app though and cross boot into Linux and finish with that :P Hope this clarifies in summation and adding... if you know what you're doing, it ìs OK. ** 32 bit and 64 bit science app computed results might work, but that depends on how the techs configure the distribution rules / if the output is sufficiently close... bit for bit matching. Case in point a discussion I had on CPDN, different CPUs e.g. AMD+Intel quorums don't exactly match.

There's 2 things to consider, the 1st. is homogenity. While not so common, it is possible to use very fine homogenity-grouping, meaning even both OS is win/64, the XP-64 and Win7-64 gets put in a different group. If this is the case for any of WCG's projects I've no idea, if WCG isn't using so fine-grained homogenity, it won't be a problem...
----------------------------------------The 2nd. problem is access-rights. If you configure BOINC to run as a service, BOINC will create it's own special account, and configure the BOINC-directories to be accessible only to this account. Your other OS will on installation also create it's special BOINC-account, but even both accounts has got the same "name", in reality they're different accounts, and only one of your OS can therefore successfully access the BOINC Data-direcory... To fix the access-rights problem, you'll need to manually edit the access-rights on BOINC's data-directory and it's sub-directories. The easiest is just to let "everyone" have full access-rights. And regardless of how you're setting the access-rights, it will be less secure. If you're not running as service, it's less chances to run into access-right-problems, but it's still a possibility if you're not running as administrator all the time.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

I installed BOINC client to Windows XP. I put the Data Directory into a third partition which is used to store general data. I set the client to run only one job and started a job in Windows XP and let it run half an hour. Then I switched to Windows 7 and installed BOINC client choosing the same Data Directory as in Windows XP. First I set the client to run only one job, I am not sure if this was necessary by the way, and then the job started to run and still running. I will post the result here, if it is accepted or not by the system.
