now, I set $HOME as shared directory, but when doing ompi-checkpoint, it
shows:(nimbus1 is the remote machine in
[nimbus1:12630] opal_os_dirpath_create: Error: Unable to create the
sub-directory (/home/mpiu/ompi_global_snapshot_1662.ckpt/0) of
[nimbus1:12630] Error: No metadata filename specified!
why is that?
