Prefetching of memory objects in reconfigurable memory subsystems for object-based compute nodes

A compute node (500) for a multi-node computer and related prefetching method are disclosed. The compute node comprises a compute core (511) for executing tasks on memory objects, a runtime management unit (516), a memory subsystem (503; 700) with local storage controller (710), and an object management unit (502). The object management unit is configured to calculate the physical address of each memory object fragment accessible on a distributed store from a combination of an object identifier (OID) and fragment offset. The runtime management unit is configured to notify the memory subsystem of the memory object identifiers (OID) related to scheduled tasks. The local storage controller is configured to detect the object type included in the metadata portion of each notified memory object and command prefetching of a type-dependent number of fragments of the notified memory object, or another memory object referred to in the metadata portion, from a deeper level of the memory subsystem or the distributed stor
