The BOINC software should be able to take care of this without intervention from you.

A power failure took down my two machines early this summer. When I started them back up, BOINC picked up the in-progress WUs at the most recent checkpoint and continued on without generating errors.

several weeks to a few months ago, my computer returned an "invalid" result for no apparent reason. Do you recommend that I reset the project? since then, projects other than dddt2 have returned several valid results. (I don't know about ddd2 because workunits for ddd2 are so rare.) Thanks!

I am surprised that so few people have their machines powered by an Uninterruptable Power Supply (UPS). For me, the problem does not arise, even though I lose power for a second or two very frequently, and for 10 minutes or so from time to time. The record was power loss for about 4 days.

In all these cases, if the interruption is short, the UPS just coasts over the interval and the computer gets power continuously. If the power loss is too long for the UPS, the ups signals the computer to do a controlled shutdown.

gb009761, count yourself blessed in that respect although, I must say, I prefer my climate!

Over the years I've gone through four or five UPS's as we often have spikes and dips in the electricity. A few years ago the national supply situation resulted in regular "load-shedding" of whole towns or suburbs for two or more hours at a time, every two or three days. The UPS would then run flat. I do not recall any issues with BOINC. One does need to bear in mind applications which have long gaps in checkpointing, like Clean Energy.
