Energy Balance between Voltage-Frequency Scaling and Resilience for Linear Algebra Routines on Low-Power Multicore Architectures
Catalán, Sandra; Herrero, José R.; Quintana-Orti, Enrique S.; Rodríguez Sánchez, Rafael Elsevier (2018)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 ... -
Look-ahead in the two-sided reduction to compact band forms for symmetric eigenvalue problems and the SVD
Rodríguez Sánchez, Rafael; Catalán, Sandra; Herrero, José R.; Quintana-Orti, Enrique S.; Tomás Domínguez, Andrés Enrique Springer Verlag (2019)We address the reduction to compact band forms, via unitary similarity transformations, for the solution of symmetric eigenvalue problems and the computation of the singular value decomposition (SVD). Concretely, in the ... -
Static scheduling of the LU factorization with look-ahead on asymmetric multicore processors
Catalán, Sandra; Herrero, José R.; Quintana-Orti, Enrique S.; Rodríguez Sánchez, Rafael Elsevier (2018)We analyze the benefits of look-ahead in the parallel execution of the LU factorization with partial pivoting (LUpp) in two distinct “asymmetric” multicore scenarios. The first one corresponds to an actual hardware-asymmetric ... -
Two-sided orthogonal reductions to condensed forms on asymmetric multicore processors
Alonso-Jordá, Pedro; Catalán, Sandra; Herrero, José R.; Quintana-Orti, Enrique S.; Rodríguez Sánchez, Rafael Elsevier (2018)We investigate how to leverage the heterogeneous resources of an Asymmetric Multicore Processor (AMP) in order to deliver high performance in the reduction to condensed forms for the solution of dense eigenvalue and ...
