One of the best ways of improving utilization is to balance the load by taking into account the heterogeneity of these clusters. This article presents a novel way of expressing computational capacity, more adequate for heterogeneous clusters, and also advocates for task migration in order to further improve the utilization. The experimental evaluation shows that both proposals are advantageous and allow improving the utilization of heterogeneous clusters and reducing the makespan to 16.7% and 17.1%, respectively.}, organization = {This work has been supported by the Spanish Science and Technology Commission under contracts TIN2016-76635-C2-2-R and TIN2016-81840-REDT (CAPAP-H6 network) and the European HiPEAC Network of Excellence}, publisher = {Kluwer Academic Publishers}, publisher = {J Supercomput 76, 8787-8800 (2020)}, title = {Improving utilization of heterogeneous clusters}, author = {Stafford Fernández, Esteban and Bosque Orero, José Luis}, }
