Ticket #273. Introduction. I/O is . one . of the main bottlenecks in HPC applications.. Many applications or higher level libraries rely on MPI-I/O for doing parallel I/O.. Several optimizations have been introduced in MPI-I/O to meet the needs of application. Rui. Wang, . Erlin. Yao, . Pavan. . Balaji. , Darius . Buntinas. , . Mingyu. Chen, and . Guangming. Tan.
