I don't know of any such specific documentation but the flag values are defined in: orte/util/attr.h:54 (openmpi-3.1.4) The difference between your nodes (bit value 0x2) means: #define ORTE_NODE_FLAG_LOC_VERIFIED 0x02 // whether or not the location has been verified - used for // environments where the daemon's final destination is uncertain I do not know what that means exactly but it is not related to pinning on or off. Seems to indicate a broken launch and/or install and/or environment. /Peter K
