Hi

I have tried to transfer the whole BOINC-folder to another faster computer. I hoped it would run faster there, but the other computer downloaded another WU instead of contiuing on the one already started. I have access to a bette PC for a while and want to speed up the crunching.

How can I let another PC finish the WU?
If it is not finished om the new PC, Can I take it back again?

Thank you

On the \'slow\' computer:
1) Click Network activity suspended. (Somewhere in the menu. Stops BOINC blabbing to the server if you do something wrong.)
2) Click Suspend in the \"run\" section. (Also somewhere in the menu.)
3) Wait until the work units (in Tasks) says Activities suspended. (NOT Activities suspended by user, which happens first.)
4) Click Exit in the menu. ( It\'s VERY important not to have BOINC running before moving!)

5) Copy the ENTIRE boinc folder to the \'fast\' computer. If you use a cd/dvd, then it\'s best to zip the lot first. This will preserve the status of the read/write flags. Otherwise you have to reset everything afterwards.

6) Download and reinstall BOINC in the BOINC folder on the new computer. This is to get the registry settings correct. (For BOINC versions of 5.*, just overwrite the existing copy moved from the \'slow\' computer.)

To put it all back onto the \'slow\' computer, just do the same as above, replacing \"fast\' with \'slow\', and \'slow\' with \'fast\'.

A possible reason for getting a new model, (as per your message), is that you put the installation into a different location on the \'fast\' computer\', so that BOINC couldn\'t find all of the files it needed, and started again.

Have you got both models on the better PC, the transferred model + the new model?

If this is the case, open your boinc manager. In the Projects tab, highlight \'climateprediction\' and click the Don\'t get new tasks button, once only.

In the Tasks/Work tab, highlight the new model you don\'t want to run and click the Suspend button.

The other (transferred) model should now start running.

When the transferred model is running properly, in the Tasks tab you could if you want highlight the unwanted model and click Abort.

It worked.
Thank you

Oke, how about a Linux-machine ?

My (single) Linux-machine no longer has access to the internet. The only option to save it\'s work (and 7 days of trickles) is to copy the project-data to a windowz-box and let it send its results to CPDN.
I\'m quite confident that data-files will be interchangeable since most files are XML-based.

Any suggestions to what files I should (not) copy ?

Thanks, Leon

I\'m not sure it\'ll be that easy. But there is one further alternative - download a linux virtual machine (such as VMWare), and run that on the windows box. Make sure the Windows boinc is suspended when you\'re doing that. Run the backup of the Linux boinc in the VM in order to get it to upload the trickles.

It might be possible Leon, and the best approach definitely includes Mike\'s advice of running a Linux virtual machine on your Windows system to reduce the amount of work you need to do.

My suggestion would be the following sequence:

• suspend computation and networking on the Linux system.
  
• copy the complete BOINC directory to the Windows system. If that\'s also running BOINC stop it (to avoid any possible conflicts).
  
• run the copied BOINC under the Linux VM. Enable networking. That should trigger all the project communication that\'s required, but if not request project updates manually. Disable networking, stop BOINC and restart the native Windows BOINC.
  
• copy the modified BOINC directory back to the Linux system (you might want to manually edit client_state.xml to restore the original <host_info> block for the system, but I don\'t think that\'ll be absolutely necessary). Restart BOINC and enable computation.

Why didn\'t I think of VMWare ... stupid me.
I surely will try doing this.

Yes, it worked. :-)

Excellent :-)
