Scheduling with QoS in parallel I/O systems
Ajay Gulati, Peter Varman · 2004
Parallel I/O architectures are increasingly deployed for high performance computing and in shared data centers. In these environments it is desirable to provide QoS-based allocation of disk bandwidth to different applications sharing the I/O system. In this paper, we introduce a model of disk bandwidth allocation, and provide efficient scheduling algorithms to assign the bandwidth among the concurrent applications.
