First, we characterize application performance on dedicated clusters and cloud to obtain application signatures. ... This paper presents a scheme to optimize the mapping of HPC applications to a set of hybrid dedicated and cloud resources. ... In the future, we plan to extend the mapping tool to also perform a dynamic adjustment of the static mapping through run-time monitoring.

Ensuring good performance for Hadoop is paramount for the wide-range of applications built on top of it. In this paper we analyze Hadoop's behavior under failures involving compute nodes. ... The reason is that Hadoop focuses on extreme scalability and thus trades off possible improvements resulting from sharing failure information between tasks. ...
