Reservation Required for Modes Other than Quad,Cache on Cori KNL

http://www.nersc.gov/users/announcements/new-policy-changes-in-allocation-year-2018/

All KNL nodes in Cori will be provisioned in Quad,Cache mode beginning January 9, 2018. Users who want to run in other KNL modes must request a reservation in advance. NERSC is requiring this because most codes run well in Quad,Cache and changing KNL modes requires a lengthy reboot that makes less compute time available to users.

At the start of AY18 on January 9, batch jobs still in the queue requesting any modes other than quad,cache will be removed, and new jobs requesting such will fail at submission.

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.
