The backend is selected at runtime via the ``MercuryProtocol`` engine parameter, with an ``SST_MERCURY_PROTOCOL`` environment-variable fallback. On Slingshot, the required OFI auth key is supplied automatically from ``SLINGSHOT_VNIS``. See the SST engine documentation for details. ====================== What's new in v2.12? ====================== Loading Loading
