System and method for supporting dual-port virtual router in a high performance computing environment

A method for supporting dual-port virtual router in a high performance computing environment, comprising:

• providing, at one or more computers, each computer comprising one or more microprocessors,
• a first subnet, the first subnet comprising
• a plurality of switches, wherein each of the plurality of switches comprises a plurality of switch ports,
• a plurality of host channel adapters, and
• a subnet manager;
• configuring a switch port on a switch of the plurality of switches as a router port;
• logically connecting the switch port configured as the router port to a virtual router, the virtual router comprising at least two virtual router ports, the switch port configured as a router port being connected to a first virtual router port of the at least two virtual router ports of the first subnet;
• and
• interconnecting the first subnet with a second subnet via a physical link, a first end of the physical link being attached to a second virtual router port of the at least two virtual router ports of the first subnet, a second end of the physical link being attached to a virtual router port of the second subnet.

A non-transitory computer readable storage medium, including instructions stored thereon for supporting dual-port virtual router 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, each computer comprising one or more microprocessors,
• a first subnet, the first subnet comprising
• a plurality of switches, wherein each of the plurality of switches comprises a plurality of switch ports,
• a plurality of host channel adapters, and
• a subnet manager;
• configuring a switch port on a switch of the plurality of switches as a router port;
• logically connecting the switch port configured as the router port to a virtual router, the virtual router comprising at least two virtual router ports, the switch port configured as a router port being connected to a first virtual router port of the at least two virtual router ports of the first subnet;
• and
• interconnecting the first subnet with a second subnet via a physical link, a first end of the physical link being attached to a second virtual router port of the at least two virtual router ports of the first subnet, a second end of the physical link being attached to a virtual router port of the second subnet.
