Abstract: Applications running on high performance computing systems share I/O resources, including parallel file systems. This sharing often results in inter-application I/O interference and degraded I/O performance. In this work, we study the benefits of coordinating between applications to reduce I/O interference and develop methods to perform this coordination. Our results show performance improvements of 42% over uncoordinated runs with very low overhead.
