Abstract

Current parallel scientific applications generate a huge amount of data that must be managed efficiently for the HPC storage systems. However, the I/O performance depends on the application I/O behavior and the configuration of the underlying I/O system. To understand the I/O behavior in the software stack and its impact on the I/O operations defined in the application logic, we propose a design framework named PIOM-PX, which allows to define an I/O behavior model based on the I/O phases of HPC applications at POSIX-IO level. We validate our framework using the IOR benchmark for four I/O patterns and we analyze the I/O behavior of NAS BT-IO.
