    Change a flag in cc_config.xml and restart Boinc, and 2 copies of PrimaBonica restart, and 6 hours of PrimaBoinca work gone. Reboot another computer, and 8 jobs restart, and 8 hours of work gone. Is there any chance someone could take a look at why the PrimaBoinca client is not checkpointing? Or proclaim that the present behavior is a feature and not a bug?

      I have the same problem on my MACbook. I'm sorry but I'm not going to waste my CPU time like this. Each time my laptop goes to sleep, the WU starts at 0% again. This I find not acceptable and if I will leave this project shortly if it is not fixed.

        Once the checkpoints work (with preferably much longer intervals than 1s between writes to disk) I'd appreciate a message saying something to that effect. Until then I'm off the project. The last WU ran with high priority to 85%, then the app switched and I lost all the work. That was when I aborted the WU and I'm not crunching another one until this issue is resolved.

        Once it is, I'm happy to return to the project.

        Cheers

          Thanks for posting this, it explains why I am having a bunch of work units timeout. I am also off this project till it gets fixed.

            I'm done with this project as well. I cannot control the length of the WU, and since I am crunching for a lot of other projects, I need the process to switch between work.
            If the administrators don't know how to do checkpointing, or how to pause results and resume, there are pleanty of perople running sits that can help them along. Heck, Aqua has even figured out how to use multiple process cores on a single WU to help speed processing.

            It can be done
            It must be done.
            Will it be done?

                Hey, thats good to hear. I like to help with science, but I also hate to waste CPU cycles and power. I'm sure that you can figure this out and make the system and work units more stable. I'll check back in a few weeks.

                  Thanks for looking into it, Fabio. Please post here or on the home page news when you think you've got CPing working. I, too, will be glad to resume crunching then.

                          Nice to know ...

                          BTW: the linux client (version 7.06) is also checkpointing.

                              I tried it beginning of Feb or so: if you have a mac (running OS X 10.5.8) I think you are still out of luck...

                                  It seems, the problem with having no checkpoints still exists for MacOS. I have several tasks of primaboinca running, but everytime the BOINC client decides to switch to another application or I shut down my MacBook the primaboinca tasks start from zero when BOINC resumes them.

                                    Darn. I just paused a WU @75% and when I restarted it, back to 0%.

                                    So OSX checkpointing still not working. I'll finish the 2 WUs I've got then i'll be off somewhere else.
