....mismatch between the physical layout of the data and the layout required by the application program. Studies of parallel file systems available on parallel supercomputers have shown that severe mismatch between physical and logical views can result in overheads that exceed even serial performance [5]. Much of this phenomenon is due to an increase in the amount of control data passed as individual data requests become smaller. An even more extreme impact is seen in situations where data must be repeatedly fetched from the I O device because of false sharing between different application tasks. ....
