I/O scheduling strategy for HPC applications

With the ever-growing need of data in HPC applications, the congestion at the I/O level becomes critical in supercomputers. Architectural enhancement such as burst buffers and pre-fetching are added to machines, but are not sufficient to prevent congestion. Recent online I/O scheduling strategies have been put in place, but they add an additional congestion point and overheads in the computation of applications.

In this project, we studied application pattern (such as periodicity), in order to develop efficient scheduling strategies [7], [32] for their I/O transfers.
