Provided are a method, system, and program to allocate tasks among a plurality of processes within a distributed processing environment. Each process secures a list of elements and performs a first operation on an element of the list to produce a result corresponding to one of the processes. If the result corresponds to the process processing the element, the process performs a second operation on the element. Each process then processes the next element on the list until all the elements of the list are processed. After the process processes all the elements on the list it further processes each element remaining on the list and performs the second operation on the elements remaining on the list. In one implementation, the distributed processing environment is a peer-to-peer virtual storage system and each process runs on a controller controlling a plurality of storage systems.
