[Users] simfactory job restart

[Vassilios Mewes]

Hello Ian,

yes, this has happened to me.. I didn't use a shred checkpoint directory,
and some runs have started from the initial data again..deleting all
folders output-NNNN without a valid termination checkpoint will remedy this?

to use a shared checkpoint directory for future runs: is it sufficient to
just use

io::checkpoint_dir                    = "../checkpoints"
io::recover_dir                         = "../checkpoints"

??

best wishes,

Vassili
