US 2018/0324094 A1 · SYSTEM AND METHOD FOR SUPPORTING INTER SUBNET PARTITIONS IN A HIGH PERFORMANCE COMPUTING ENVIRONMENT

Abstract

Systems and methods for supporting inter subnet partitions in a high performance computing environment. In accordance with an embodiment, a fabric manager can define a range of P_Key values, among a plurality of P_Key values, as a inter subnet partition (ISP) P_Key range. The fabric manager can communicate this defined range of P_Key values to a number of subnets, via their subnet managers. The subnet managers in each subnet retain management over their subnets. As there is no central management that configures each side of inter subnet communication, subnet managers on within participating subnets can set up ISP membership, and then exchange information with the other subnet.

Dependent claims

A system for supporting inter subnet partitions in a high performance computing environment, comprising:

one or more microprocessors;
a first subnet, the first subnet comprising
a plurality of switches,
a plurality of host channel adapters,
a subnet manager, and
an inter subnet manager;
a fabric manager, the fabric manager residing in the high performance computing environment;
wherein a switch port on a 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 fabric manager defines a range of partition key (P_Key) values within a plurality of partition key values, the defined range of partition key values comprising an Inter Subnet Partition (ISP) P_Key range;
and
wherein the fabric manager communicates to the subnet manager the ISP P_Key range.
