The authors propose a compilation scheme for parallel processing near fine-grain tasks, each of which consists of several instructions or a statement, on a multiprocessor system called OSCAR. The scheme allows one to minimize synchronization and data transfer overheads and to optimally use registers of each processor by employing a static scheduling algorithm considering data transfer. This scheme can effectively be combined with macro-dataflow computation and with making the loop concurrent. A compiler using the proposed scheme has been implemented on OSCAR, which has been designed to take full advantage of the static scheduling. A performance evaluation of the scheme on OSCAR is also described
