Engaging a "Multirail" network is a method to by-pass this. In this paper, we design a non-threaded and a threaded approach to improve the performance of uDAPL over multirail configured clusters.  ...  The two approaches are evaluated on an InfiniBand cluster with different multirail configurations.  ...  Acknowledgment This work is part funded by Australian Research Council Grant LP0669726 and Intel Corporation, and was supported by the National Computing Infrastructure at the ANU.  ...

Region-based techniques for modeling and enhancing cluster OpenMP performance [article]

Jie Cai, University, The Australian National, University, The Australian National
To understand these systems, we evaluate their performance with different OpenMP applications, and we also develop a benchmark, called MCBENCH, to characterize the memory consistency costs.  ...  Based on the regions, we develop two region-based models to rationalize the numbers and types of the page faults and their associated costs to performance.  ...  D.5 Challenge and Conclusion In this Appendix, we have developed the non-threaded and the threaded approaches with uDAPL to explore the bandwidth improvement on multirail networks.  ...
