Hi I'm looking for some advice...

I am hoping to change my base machine from Windows to Ubuntu. I currently have a folder on Drive F: called boinc containing many files and the subdirectories projects, slots, symbols.

Can I copy this directory straight to an ubuntu installation and continue processing in Linux Boinc where I stopped in Windows Boinc...?

Or will I have to finish all Windows models and start a fresh in my new Ubuntu install?

Thanks

The executables for Windows/Linux/Mac are all different.
Finish what you've got, report them, then switch.

BTW

If I already have 4 models that Boinc has downloaded in anticipation of starting but they have not started is there any way I can 'return' those fresh models to the server for someone else to do?

Obviously I don't expect to send the files back but can I notify the server that they will not be executed and hopefully another machine can get them?

Cheers

Aborting each task should allow for the resend to occur.

OK, I have aborted four models before they started and selected 'No new Tasks' while my current models continue crunching.

Thanks

Digby, fyi, I've been running ubuntu and cpdn on an Intel platform for a while now. I don't look at the ubuntu box very often, it's the print server, and it ticks along for weeks without any help. However there are two noticeable issues:

1. Cpdn runs about 30% slower on ubuntu than on XP-doze, with the current hadam and hadcm models.

2. The gnome desktop occasionally likes to go to sleep, although cpdn tasks are still running in the background. To get it's attention, if all else fails, "Raising skinny elephants" usually does the trick to safely quiesce everything and restart.
