    • openAccess   An study of the effect of process malleability in the energy efficiency on GPU‑based clusters 

      Iserte, Sergio; Rojek, Krzysztof Springer (2019-10-21)
      The adoption of graphic processor units (GPU) in high-performance computing (HPC) infrastructures determines, in many cases, the energy consumption of those facilities. For this reason, an efficient management and ...

    • openAccess   DMR API: Improving cluster productivity by turning applications into malleable 

      Iserte, Sergio; Mayo, Rafael; Quintana-Orti, Enrique S.; Beltrán, Vicenç; Peña Monferrer, Antonio J. Elsevier (2018)
      Adaptive workloads can change on–the–fly the configuration of their jobs, in terms of number of processes. To carry out these job reconfigurations, we have designed a methodology which enables a job to communicate with ...

    • openAccess   DMRlib: Easy-coding and Efficient Resource Management for Job Malleability 

      Iserte, Sergio; Mayo, Rafael; Quintana-Orti, Enrique S.; Pena, Antonio J. IEEE (2020-09-09)
      Process malleability has proved to have a highly positive impact on the resource utilization and global productivity in data centers compared with the conventional static resource allocation policy. However, the non-negligible ...

    • openAccess   Dynamic reconfiguration of noniterative scientific applications A case study with HPG aligner 

      Iserte, Sergio; Martínez Pérez, Héctor; Barrachina Mir, Sergio; Castillo Catalán, María Isabel; Mayo, Rafael; Peña Monferrer, Antonio J. Springer (2018-09)
      Several 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 ...
