Abstract: 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.

Abstract: 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.

Abstract translation: 当检测到具有信号丢失的不安全端口时，收发器可以在与不安全端口相关联的一组激光器中启用一个激光器，并且可以禁用剩余的激光器。 然后，收发器可以指示与一个激光器相关联的发射器在不安全端口上使用小于与类别1条件相关联的阈值的衰减的发射功率以及在与其他激光器中的能量激光器不同的时间 激光组。 或者，对于在其上接收有效通信的安全端口，收发器可以使得与安全端口相关联的一组激光器中的激光器成为可能。 然后，收发器可以指示与这组激光器中的激光器相关联的发射器使用大于阈值的激光器的正常发射功率在安全端口上传输光信号。
