A Case for Malleable Thread-Level Linear Algebra Libraries: The LU Factorization With Partial Pivoting
Catalán, Sandra; Herrero Zaragoza, José R.; Quintana-Orti, Enrique S.; Rodríguez Sánchez, Rafael; Van de Geijn, Robert A. IEEE (2019-01)We propose two novel techniques for overcoming load-imbalance encountered when implementing so-called look-ahead mechanisms in relevant dense matrix factorizations for the solution of linear systems. Both techniques target ... -
Energy Balance between Voltage-Frequency Scaling and Resilience for Linear Algebra Routines on Low-Power Multicore Architectures
Catalán, Sandra; Herrero Zaragoza, José R.; Quintana-Orti, Enrique S.; Rodríguez Sánchez, Rafael Elsevier (2017)Near Threshold Voltage (NTV) computing has been recently proposed as a technique to save energy, at the cost of incurring higher error rates including, among others, Silent Data Corruption (SDC). In this paper, we evaluate ... -
Multi-threaded dense linear algebra libraries for low-power asymmetric multicore processors
Catalán, Sandra; Herrero Zaragoza, José R.; Igual, Francisco; Rodríguez Sánchez, Rafael; Quintana-Orti, Enrique S.; Adeniyi-Jones, Chris Elsevier (2018-03)Dense linear algebra libraries, such as BLAS and LAPACK, provide a relevant collection of numerical tools for many scientific and engineering applications. While there exist high performance implementations of the BLAS ...
