Open AccessSeveral studies have proved the benefits of job malleability, that is, the capacity of an application to adapt its parallelism to a dynamically changing number of allocated processors. The most remarkable advantages of ...
Iserte, Sergio; Mayo, Rafael; Quintana-Ortí, Enrique S.; Beltran Querol, Vicenç; Peña, Antonio J. (IEEE, 2017-09-07)
Open AccessIn this paper we introduce a methodology for dynamic job reconfiguration driven by the programming model runtime in collaboration with the global resource manager. We improve the system throughput by exploiting malleability ...
