Work stealing and persistence-based load balancers for iterative overdecomposed applications

Jonathan Lifflander, Sriram Krishnamoorthy, Laxmikant V. Kale
2012 Proceedings of the 21st international symposium on High-Performance Parallel and Distributed Computing - HPDC '12  
The work to be performed is overdecomposed into tasks, enabling automatic rebalancing by the middleware.  ...  In this paper, we consider the design and evaluation of two distinct approaches to addressing this challenge: persistence-based load balancing and work stealing.  ...  HPDC'12, June 18-22, 2012, Delft, The Netherlands.

Exploring the performance and mapping of HPC applications to platforms in the cloud

Abhishek Gupta, Laxmikant V. Kalé, Dejan S. Milojicic, Paolo Faraboschi, Richard Kaufmann, Verdi March, Filippo Gioachin, Chun Hui Suen, Bu-Sung Lee
2012 Proceedings of the 21st international symposium on High-Performance Parallel and Distributed Computing - HPDC '12  
This paper presents a scheme to optimize the mapping of HPC applications to a set of hybrid dedicated and cloud resources.  ...  We also find that the execution overhead in cloud can be minimized to a negligible level using thin hypervisors or OS-level containers.  ...  In the future, we plan to extend the mapping tool to also perform a dynamic adjustment of the static mapping through run-time monitoring.
