Abstract
A method for memory access is applied in a cluster of computers linked by a network. For a given computer, a respective physical memory range is defined including a local memory range within the local RAM of the given computer and a remote memory range allocated to the given compute within the local RAM of at least one other computer in the cluster, which is accessible via the network using the network interface controllers of the computers. When a memory operation is requested at a given address in the respective physical memory range, the operation is executed on the data in the local RAM of the given computer when the data at the given address are valid in the local memory range. Otherwise the data are fetched from the given address in the remote memory range to the local memory range before executing the operation on the data.
