  • A trace-scaling agent for parallel application tracing. 

    Freitag, Fèlix; Caubet Serrabou, Jordi; Labarta Mancho, Jesús José (IEEE, 2002)
    Conference report
    Open Access
    Tracing and performance analysis tools are an important component in the development of high performance applications. Tracing parallel programs with current tracing tools, however, easily leads to large trace files with ...
  • Exploring the predictability of MPI messages. 

    Freitag, Fèlix; Caubet Serrabou, Jordi; Farreras Esclusa, Montserrat; Cortés, Toni; Labarta Mancho, Jesús José (IEEE, 2003-04)
    Conference report
    Open Access
    Scalability to a large number of processes is one of the weaknesses of current MPI implementations. Standard implementations are able to scale to hundreds of nodes, but no beyond that. The main problem of current ...
  • On the scalability of tracing mechanisms. 

    Freitag, Fèlix; Caubet Serrabou, Jordi; Labarta Mancho, Jesús José (Springer Verlag, 2002)
    Conference report
    Open Access
    Performance analysis tools are an important component of the parallel program development and tuning cycle. To obtain the raw performance data, an instrumented application is run with probes that take measures of specific ...
