Claim of US Patent No. 10,536,374

1. A system for supporting SMA level abstractions at router ports for inter-subnet exchange of management information in a high performance computing environment, comprising:one or more microprocessors;
a first subnet, the first subnet comprising
a plurality of switches of the first subnet, wherein each of the plurality of switches comprise a plurality of switch ports,
a plurality of host channel adapters of the first subnet, each host channel adapter comprising at least one host channel adapter port,
a plurality of end nodes of the first subnet, wherein each of the end nodes are associated with at least one host channel adapter of the plurality of host channel adapters, and
a subnet manager of the first subnet, the subnet manager running on a switch of the plurality of switches, wherein the subnet manager configures the connectivity of the first subnet such that the plurality of end nodes are, via each respective host channel adapter, interconnected via the plurality of switches, wherein such configuration of the connectivity of the first subnet comprises a connectivity information of the first subnet;
wherein a switch port of the plurality of switch ports on another switch of the plurality of switches is configured as a router port;
wherein the switch port configured as the router port is logically connected to a virtual router;
wherein the another switch of the plurality of switches that comprises the switch port of the plurality of switch ports configured as a router port comprises a remotely accessible attribute;
wherein the remotely accessible attribute comprises information about the first subnet, the information about the first subnet comprising at least the connectivity information of the first subnet; and
wherein, in response to a receiving a query, at the another switch of the plurality of switches, from a subnet manager of a second subnet, the connectivity information contained in the remotely accessible attribute is provided to the subnet manager of the second subnet.
