System and method for supporting router sma abstractions for smp connectivity checks across virtual router ports in a high performance computing environment

A method for supporting SMP-based connectivity checks across virtual router ports in a high performance computing environment, comprising:

• providing, one or more computers include a microprocessor;
• providing a first subnet, the first subnet comprising
• a switch of the first subnet comprising a plurality of switch ports and a subnet management agent (SMA) of the first subnet, wherein a switch port of the switch of the first subnet is configured as a router port of the first subnet,
• a plurality of host channel adapters of the first subnet, each host channel adapter comprising at least one host channel adapter port, and
• a subnet manager of the first subnet;
• and
• providing a second subnet, the second subnet comprising
• a switch of the second subnet comprising a plurality of switch ports, wherein a switch port of the switch of the second subnet is configured as a router port of the second subnet;
• interconnecting the first subnet with the second subnet via the router port of the first subnet;
• sending, by the subnet manager of the first subnet, a first request packet to the router port of the first subnet;
• creating, by a SMA of the first subnet operating as a proxy, a new request packet, and
• forwarding, by the SMA of the first subnet operating as the proxy, the new request packet to the second subnet.

A non-transitory computer readable storage medium, including instructions stored thereon for supporting SMP-based connectivity checks across virtual router ports 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, one or more computers include a microprocessor;
• providing a first subnet, the first subnet comprising
• a switch of the first subnet comprising a plurality of switch ports and a subnet management agent (SMA) of the first subnet, wherein a switch port of the switch of the first subnet is configured as a router port of the first subnet,
• a plurality of host channel adapters of the first subnet, each host channel adapter comprising at least one host channel adapter port, and
• a subnet manager of the first subnet;
• and
• providing a second subnet, the second subnet comprising
• a switch of the second subnet comprising a plurality of switch ports, wherein a switch port of the switch of the second subnet is configured as a router port of the second subnet;
• interconnecting the first subnet with the second subnet via the router port of the first subnet;
• sending, by the subnet manager of the first subnet, a first request packet to the router port of the first subnet;
• creating, by a SMA of the first subnet operating as a proxy, a new request packet, and
• forwarding, by the SMA of the first subnet operating as the proxy, the new request packet to the second subnet.
