CALCioM: Mitigating I/O Interference in HPC Systems through Cross-Application Coordination

Matthieu Dorier, Gabriel Antoniu, Rob Ross, Dries Kimpe, Shadi Ibrahim
2014 2014 IEEE 28th International Parallel and Distributed Processing Symposium  
This paper focuses on CALCioM, a framework that aims to mitigate I/O interference through the dynamic selection of appropriate scheduling policies.  ...  Unmatched computation and storage performance in new HPC systems have led to a plethora of I/O optimizations ranging from application-side collective I/O to network and disk-level request scheduling on  ...  We also thank Michel Raynal for our fruitful discussion on mutex algorithms, Rob Latham and the PVFS2 and Mpich developers for their help in understanding their tools.  ...

Client-side Straggler-Aware I/O Scheduler for Object-based Parallel File Systems [article]

Neda Tavakoli, Dong Dai, Yong Chen
2018 arXiv   pre-print
First, we introduce a client-side, log-assisted, straggler-aware I/O scheduler architecture to tackle the storage straggler issue in HPC systems.  ...  In this paper, we introduce a log-assisted straggler-aware I/O scheduling to mitigate the impact of storage server stragglers. The contribution of this study is threefold.  ...  CALCioM [25] mitigates I/O interferences in HPC systems through a cross-application coordination.  ...

Omnisc'IO: A Grammar-Based Approach to Spatial and Temporal I/O Patterns Prediction

Matthieu Dorier, Shadi Ibrahim, Gabriel Antoniu, Rob Ross
2014 SC14: International Conference for High Performance Computing, Networking, Storage and Analysis  
In order to further improve these techniques, modeling and predicting spatial and temporal I/O patterns of HPC applications as they run has became crucial.  ...  In this paper we present Omnisc'IO, an approach that builds a grammar-based model of the I/O behavior of HPC applications and uses it to predict when future I/O operations will occur, and where and how  ...  This work was done in the framework of a collaboration between the KerData joint Inria -ENS Rennes -Insa Rennes team and Argonne National Laboratory within the Joint INRIA-UIUC-ANL Laboratory for Petascale  ...

Using Formal Grammars to Predict I/O Behaviors in HPC: The Omnisc'IO Approach

Matthieu Dorier, Shadi Ibrahim, Gabriel Antoniu, Rob Ross
2016 IEEE Transactions on Parallel and Distributed Systems  
In order to further improve these techniques, modeling and predicting spatial and temporal I/O patterns of HPC applications as they run has become crucial.  ...  In this paper we present Omnisc'IO, an approach that builds a grammar-based model of the I/O behavior of HPC applications and uses it to predict when future I/O operations will occur, and where and how  ...  In our previous work [4] we advocated for crossapplication coordination to mitigate I/O interference.  ...
