Reservation-based I/O Performance Guarantee for MPI-IO Applications using Shared Storage Systems

Presentation Type: 

There is a big problem in concurrent use of the parallel storage systems on HPC Clusters. This might spoil the performance improvement that might otherwise be obtained by optimizations of MPI-IO, such as data sieving, two-phase collective I/O and etc.
Our approach to achieve performance guarantees is to allow users / applications to explicitly reserve I/O throughput of the storage system in advance, with start and end time of the access.
