YO9-91-007 SCIENTIFIC VISUALIZATION SYSTEM ABSTRACT OF HE DISCLOSURE A multiprocessor data processing system (10), and a method of operating same, so as to provide efficient bandwidth utilization of shared system resources (24, 26). The system includes a plurality of processor nodes, each of which includes a data processor (22a, 28a). In accordance with a method of the invention a first step buffers data written by a data processor to a first bus (23a), prior to the data being transmitted to a second bus (32). A second step also buffers byte enable (BE) signals generated by the data processor in conjunction with the data written by the data processor. A third step performs a main memory (26) write operation by the steps of: transmitting the buffered data to the second bus; responsive to the stored BE signals, also transmitting a control signal for indicating if a memory write is to be accomplished as a read-modify-write (RMW) type of memory operation; and transmitting the stored BE signals to the second bus. A further step couples the data, the RMW signal, and the BE signals from the local bus to a third bus (24) for reception by the main memory. Interface circuitry (34) associated with the main memory is responsive to the RMW signal for (a) reading data from a specified location within the main memory, (b) selectively merging the transmitted data in accordance with the BE signals, and (c) storing the previously read and merged data back into the specified location.
