Yesterday someone tried to force an extra large crumpet into an already toasting toaster. A fuse flipped and my servers went down. When they had recovered most workunits recovered more or less. In particular the CUL LLR and GFN18 had been almost finished. The CUL LLR went onto finish at the expected time but the GFN18 seems to have gone back to the beginning. What happened?

This is obviously just a guess.

Maybe the checkpoint file was corrupted, so it wasn't able to restart from the checkpoint and had to restart from the beginning. That would happen if the application was writing to the checkpoint about at the time the power was lost. That happens especially often if the OS is caching writes to disk and your application is writing a file frequently. I had that happen a lot with one of my personal projects – the files it wrote to would come up zeroed-out after an unexpected crash or power loss.

Unexpected power loss tends to randomly corrupt open files. Any time I lose power at my house, the not-so-critical systems not on UPSes tend to have errors on about half their tasks. Very short outages (more like an extended flicker where it's out for just a second or less) where the PSUs have enough power in the capacitors to not actually power down tend to error out most of the tasks on mine.

That works as long as the UPS isolates the toaster from the mains. You could use a super cheap one, since a pure sine wave isn't needed for toasting.

How about a redundant toaster? You can keep it at the disaster recovery centre.

I suppose one day toasters will have more computing power than the computers used on the Apollo missions. When will we be running primegrid on our toasters?
