ABSTRACT:
In a computer including an operating system comprising a virtual storage organization concept providing storage space for parallel program execution in pre-allocated partitions of a virtual address storage containing shared areas and private areas in several address spaces, there are provided dynamic partitions (P1, P2, . . . N1, N2, . . . O1, O2, . . . ) that are allocatable in addition to the pre-allocated partitions (F1-F8, FA, FB, BG), in dependance from the job to be performed and that are de-allocated after job termination to free the storage area for subsequent use. This concept enlarges the virtual storage area, uses the provided space more effectively and allows the parallel execution of more programs.
