Abstract: When a user program is processed on a parallel computer system, individual processes of the user program are executed concurrently on different processors. The situation may arise here that a first process requires data generated by a second process. The first process must then wait during processing until the second process makes this data available. In order not to extend the program runtime when translating such a user program, the instructions of a first process that access data generated by a second process open result cells in a memory area that is locked for the user mode, in which the data generated by the second process is then entered. During the processing of the user program after the translation for the parallel computer system, all instructions with memory access are examined to determine whether the addressed memory location is a result cell in the locked memory area.
