In a computing system, memory may be managed by using a distributed array, which is a global set of local memory regions. A segment in the distributed array is allocated and is bound to a physical memory region. The segment is used by a workgroup in a dispatched data parallel kernel, wherein a workgroup includes one or more work items. When the distributed array is declared, parameters of the distributed array may be defined. The parameters may include an indication whether the distributed array is persistent (data written to the distributed array during one parallel dispatch is accessible by work items in a subsequent dispatch) or an indication whether the distributed array is shared (nested kernels may access the distributed array). The segment may be deallocated after it has been used.
