Abstract
Systems and methods for providing RDMA (remote direct memory access) read requests as a restricted feature in a high performance computing environment. An exemplary method can provide, at one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, a plurality of host channel adapters, wherein each of the host channel adapters comprise at least one host channel adapter port, and wherein the plurality of host channel adapters are interconnected via the plurality of switches, and a plurality of end nodes, including a plurality of virtual machine. The method can associate a host channel adapter with a selective RDMA restriction. The method can host a virtual machine of the plurality of virtual machines at the host channel adapter that comprises a selective RDMA restriction.
