In one embodiment, a virtual NUMA machine is formed from multiple computers coupled to a network. Each computer includes a memory and a hardware device coupled to the memory. The hardware device is configured to communicate on the network, and more particularly is configured to perform remote direct memory access (RDMA) communications on the network to access the memory in other computers. A guest physical address space of the virtual NUMA machine spans a portion of the memories in each of the computers, and each computer serves as a home node for at least one respective portion of the guest physical address space. A software module on a first computer uses RDMA to coherently access data on a home node of the data without interrupting execution in the home node. |
