  • Active measurement of memory resource consumption 

    Casas, Marc; Bronevetsky, Greg (IEEE, 2014)
    Conference report
    Open Access
    Hierarchical memory is a cornerstone of modern hardware design because it provides high memory performance and capacity at a low cost. However, the use of multiple levels of memory and complex cache management policies ...
  • Active Measurement of the Impact of Network Switch Utilization on Application Performance 

    Casas, Marc; Bronevetsky, Greg (IEEE, 2014)
    Conference report
    Open Access
    Inter-node networks are a key capability of High-Performance Computing (HPC) systems that differentiates them from less capable classes of machines. However, in spite of their very high performance, the increasing ...
  • Coherence protocol for transparent management of scratchpad memories in shared memory manycore architectures 

    Álvarez, Lluc; Vilanova, Lluís; Moreto Planas, Miquel; Casas, Marc; González Tallada, Marc; Martorell Bofill, Xavier; Navarro, Nacho; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2015)
    Conference report
    Open Access
    The increasing number of cores in manycore architectures causes important power and scalability problems in the memory subsystem. One solution is to introduce scratchpad memories alongside the cache hierarchy, forming a ...
  • Evaluation of HPC applications’ Memory Resource Consumption via Active Measurement 

    Casas, Marc; Bronevetsky, Greg (IEE, 2016)
    Article
    Open Access
    As the number of compute cores per chip continues to rise faster than the total amount of available memory, applications will become increasingly starved for memory storage capacity and bandwidth, making the problem of ...
  • Simulating whole supercomputer applications 

    González García, Juan; Casas, Marc; Giménez Lucas, Judit; Moreto Planas, Miquel; Ramírez Bellido, Alejandro; Labarta Mancho, Jesús José; Valero Cortés, Mateo (2011-06)
    Article
    Restricted access - publisher's policy
    Detailed simulations of large scale message-passing interface parallel applications are extremely time consuming and resource intensive. A new methodology that combines signal processing and data mining techniques plus a ...
