摘要： System and method for supporting flexible partition key (P_Key) mapping in a high performance computing environment. In accordance with an embodiment, when such computer environments comprise more than one subnet and/or forwarding domain that support inter-subnet partitions, the P_Keys comprising such inter-subnet partitions can change across domain boundaries. In such situations, a partition key of a packet can be updated upon entry to a new subnet and/or forwarding domain.

摘要： When an unsafe port with a loss of signal is detected, a transceiver may enable one laser in a group of lasers associated with the unsafe port and may disable the remaining lasers. Then, the transceiver may instruct a transmitter associated with the one laser to transmit an optical signal on the unsafe port using a reduced transmit power that is less than a threshold value associated with the Class 1 conditions and at a different time than enabled lasers in other groups of lasers. Alternatively, for a safe port on which valid communication is received, the transceiver may enable lasers in a group of lasers associated with the safe port. Then, the transceiver may instruct transmitters associated with the lasers in this group of lasers to transmit optical signals on the safe port using a normal transmit power for the lasers that is greater than the threshold value.
