How can I share my Burst Buffer persistent reservation with my collaborators?

If you set access permissions correctly, you can open your Burst Buffer persistent reservation with your collaborators. For example, if your reservation is called “myBBname” you can do: “chmod 770 $DW_PERSISTENT_STRIPED_myBBname/” (note that this opens the reservation to all NERSC users in your unix group). You collaborators can then access the directory via the variable $DW_PERSISTENT_STRIPED_myBBname in the usual way.
