I updated the message to explain the flags (instead of a numerical value) for OMPI v5. In brief:
#define PRRTE_NODE_FLAG_DAEMON_LAUNCHED 0x01 // whether or not the daemon on this node has been launched #define PRRTE_NODE_FLAG_LOC_VERIFIED 0x02 // whether or not the location has been verified - used for // environments where the daemon's final destination is uncertain #define PRRTE_NODE_FLAG_OVERSUBSCRIBED 0x04 // whether or not this node is oversubscribed #define PRRTE_NODE_FLAG_MAPPED 0x08 // whether we have been added to the current map #define PRRTE_NODE_FLAG_SLOTS_GIVEN 0x10 // the number of slots was specified - used only in non-managed environments #define PRRTE_NODE_NON_USABLE 0x20 // the node is hosting a tool and is NOT to be used for jobs On Apr 13, 2020, at 2:15 PM, Mccall, Kurt E.

The flags in the error message below may give a clue as to why. What is the meaning of the flag values 0x11 and 0x13? ====================== ALLOCATED NODES ====================== n006: flags=0x11 slots=3 max_slots=0 slots_inuse=2 state=UP n005: flags=0x13 slots=3 max_slots=0 slots_inuse=1 state=UP n004: flags=0x13 slots=3 max_slots=0 slots_inuse=1 state=UP n003: flags=0x13 slots=3 max_slots=0 slots_inuse=1 state=UP n002: flags=0x13 slots=3 max_slots=0 slots_inuse=1 state=UP n001: flags=0x13 slots=3 max_slots=0 slots_inuse=1 state=UP I’m using OpenMPI 4.0.3.
