Input/output for fine grain multiprocessor systems

While extensive investigations on how multiple processing elements (PEs) in a parallel system can be utilized efficiently have been carried out, the I/O (input/output) into and from the system has been ignored in most cases. However, the time for downloading input data or uploading results would not be negligible, especially when a large number of PEs such as those in a massively parallel system and/or a large volume of data are involved. Results from a preliminary study on how I/O can be efficiently realized in a fine-grain multiprocessor system without any hardware change are reported
