Research Abstract |
Parallel I/O interface in the MPI standard named MPI-IO provides collective parallel I/O. We have developed two pipelined processing implementations based on an existing original implementation by using(1) multithreaded technique with the help of Pthreads and (2) asynchronous I/O APIs, and both implementations have outperformed the original implementation. Furthermore, we have addressed to utilize a multiple buffering mechanism to minimize idle times of each process, and it has outperformed the original one.
