System and method for supporting sma level abstractions at router ports for enablement of data traffic in a high performance computing environment

A method for supporting SMA level abstractions at router ports for enablement of data traffic in a high performance computing environment, comprising:

• providing, at one or more computers, including one or more microprocessors,
• a first subnet, the first subnet comprising
• one or more switches, the one or more switches comprising at least a leaf switch, wherein each of the one or more switches comprise a plurality of switch ports,
• a plurality of host channel adapters, each host channel adapter comprising at least one host channel adapter port,
• a plurality of end nodes, wherein each of the end nodes are associated with at least one host channel adapter of the plurality of host channel adapters, wherein each of the end nodes are associated with a local identifier (LID) of a plurality of local identifiers, and
• a subnet manager, the subnet manager running on one of the one or more switches and the plurality of host channel adapters;
• configuring a switch port of the plurality of switch ports on a switch of the one or more switches as a router port;
• logically connecting the switch port configured as the router port to a virtual router;
• and
• providing at the switch of the one or more switches that comprises the switch port of the plurality of switch ports configured as a router port a data attribute;
• wherein the data attribute comprises information about allowed and disallowed end nodes.

A non-transitory computer readable storage medium, including instructions stored thereon for supporting SMA level abstractions at router ports for enablement of data traffic in a high performance computing environment, which when read and executed by one or more computers cause the one or more computers to perform steps comprising:

• providing, at one or more computers, including one or more microprocessors,
• a first subnet, the first subnet comprising
• one or more switches, the one or more switches comprising at least a leaf switch, wherein each of the one or more switches comprise a plurality of switch ports,
• a plurality of host channel adapters, each host channel adapter comprising at least one host channel adapter port,
• a plurality of end nodes, wherein each of the end nodes are associated with at least one host channel adapter of the plurality of host channel adapters, wherein each of the end nodes are associated with a local identifier (LID) of a plurality of local identifiers, and
• a subnet manager, the subnet manager running on one of the one or more switches and the plurality of host channel adapters;
• configuring a switch port of the plurality of switch ports on a switch of the one or more switches as a router port;
• logically connecting the switch port configured as the router port to a virtual router;
• and
• providing at the switch of the one or more switches that comprises the switch port of the plurality of switch ports configured as a router port a data attribute;
• wherein the data attribute comprises information about allowed and disallowed end nodes.
