Server-side I/O coordination for parallel file systems
2011
Proceedings of 2011 International Conference for High Performance Computing, Networking, Storage and Analysis on - SC '11
Preserved Fulltext
Recognizing that an I/O request will not complete until all involved file servers in the parallel file system have completed their parts, in this paper we propose a serverside I/O coordination scheme for ...
Experimental results also show that the server-side I/O coordination scheme has good scalability. ...
ACKNOWLEDGMENTS The authors are thankful to Jibing Li from Illinois Institute of Technology and Robert Ross from Argonne National Laboratory for their constructive and thoughtful suggestions toward this ...

This characterization of workloads could then be used to intelligently schedule the I/O requests in the parallel file system (PFS) that most HPC systems use. ...
We also show that the I/O scheduling based on such a characterization can substantially increase the available I/O bandwidth and thus reduce the latencies for the HPC workloads. ...

We need more interaction between application I/O requirements and system software tools to help alleviate the I/O bottleneck, moving towards I/O-aware job scheduling. ...

So, I/O requests in each file domain do not necessarily issue to the parallel file system simultaneously unless they are carried out within the same iteration step. ...
Based on that observation, this paper proposes a new collective I/O strategy that reorganizes I/O requests within each file domain instead of coordinating requests across file domains, such that we can ...
These file systems provide significant parallelism by distributing data across I/O servers so that I/O requests can be served at the different I/O servers at the same time. ...

In this study, we propose a caching strategy for the TC server side based on data block relevance, which is called the correlation pattern-based caching strategy (CPCS). ...
