    • E-EON : Energy-Efficient and Optimized Networks for Hadoop 

      Fischer e Silva, Renan (Universitat Politècnica de Catalunya, 2018-05-03)
      Doctoral thesis
      Open Access
      Energy efficiency and performance improvements have been two of the major concerns of current Data Centers. With the advent of Big Data, more information is generated year after year, and even the most aggressive predictions ...

    • Job scheduling for disaggregated memory in high performance computing systems 

      Vieira Zacarias, Felippe (Universitat Politècnica de Catalunya, 2023-10-09)
      Doctoral thesis
      Open Access
      (English) In a typical HPC cluster system, a node is the elemental component unit of this architecture. Memory and compute resources are tightly coupled in each node and the rigid boundaries between nodes limits compute ...
