Currently ompi-restart does not know how to deal with an absolute or
relative path in the command line argument for the global snapshot
handle. It will always prepend the value of the MCA parameter:
snapc_base_global_snapshot_dir
Which defaults to $HOME.
So what you are seeing is (currently) to be expected. If you set the
MCA parameter to the path you are trying for as an argument to ompi-
restart then it should work (something like the below):
ompi-restart -mca snapc_base_global_snapshot_dir $HOME
ompi_global_snapshot_7056.ckpt
I opened a bug to add this capability to orte-restart. You can track
it at the link below:
https://svn.open-mpi.org/trac/ompi/ticket/1924
I am not 100% sure when I will have a chance to get to it, but
hopefully in the next few weeks.
As a side note, if you want to move the global snapshot directory to
another location you will need to update the
'global_snapshot_meta.data' file located at the root of the global
snapshot directory to reflect the path changes for the 'Snapshot
Location:' key.
Cheers,
Josh

Hello,
I think that there is a problem with the ompi-restart from the
release r-21197.
in fact ompi-restart can restart only if the checkpoint directory
is $HOME.
For example the checkpoint folder is $HOME.
if i try ompi-restart -i $HOME/ompi_global_snapshot_7056.ckpt/ it
doesn't work and i get
msbouguerra@sol-5:~$ ompi-restart -i $HOME/
ompi_global_snapshot_7056.ckpt/
--------------------------------------------------------------------------
Error: The filename (/home/grenoble/msbouguerra/
ompi_global_snapshot_7056.ckpt/) is invalid because either you have
not provided a filename
or provided an invalid filename.
Please see --help for usage.
--------------------------------------------------------------------------
and when i try : ompi-restart -i
ompi_global_snapshot_7056.ckpt/ it works and i get
msbouguerra@sol-5:~$ ompi-restart -i ompi_global_snapshot_7056.ckpt/

So when i use another folder as checkpoint directory the restart
failed
