It has been sometime since I last participated with GPUGRID so I don't remember the proper procedure to reboot a machine after a kernel update and save an in progress gpu work unit. This happened a few days ago and I ended up loosing 5 hours of crunching time causing the WU to error out following the reboot.

I have checked the cpu slot using ACMED and did not see an obvious check point file so the point of this post is to inquire if it possible to reboot an in progress work unit and if so, what is the procedure? I would hate to think that I would have to suspend future work and wait until the current project completed prior to rebooting a new kernel.

I use Fedora and boinc runs as a daemon on all my systems. Any advice greatly appreciated.

Select no new work from the project. Allow existing work to complete, then update+restart before accepting work from the project again.

hm, whenever I close the BOINC Manager by pushing the "exit" button, after a reboot of the PC GPUGRID and other projects continue their work exactly where they had interrupted it before.

I was hoping to avoid having to do that but you are correct in that it appears to be the only safe way to avoid loosing time.

I have had a couple of power outages since I first posted about this and those WU's did continue where they left off upon restarting. Leads me to believe this issue could be more WU related or just an unfortunate coincident.
