Co-Design of the Dense Linear AlgebravSoftware Stack for Multicore Processors
Héctor Martínez, Sandra Catalán, Francisco D. Igual +3
This paper advocates for an intertwined design of the dense linear algebra software stack that breaks down the strict barriers between the high-level, blocked algorithms in LAPACK…
Programming Parallel Dense Matrix Factorizations with Look-Ahead and OpenMP
Sandra Catalán, Adrián Castelló, Francisco D. Igual +2
We investigate a parallelization strategy for dense matrix factorization (DMF) algorithms, using OpenMP, that departs from the legacy (or conventional) solution, which simply extra…
A Case for Malleable Thread-Level Linear Algebra Libraries: The LU Factorization with Partial Pivoting
Sandra Catalán, José R. Herrero, Enrique S. Quintana-Ortí +2
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…
Architecture-Aware Optimization of an HEVC decoder on Asymmetric Multicore Processors
Rafael Rodríguez-Sánchez, Enrique S. Quintana-Ortí
Low-power asymmetric multicore processors (AMPs) attract considerable attention due to their appealing performance-power ratio for energy-constrained environments. However, these p…
Performance and Energy Optimization of Matrix Multiplication on Asymmetric big.LITTLE Processors
Sandra Catalán, Francisco D. Igual, Rafael Mayo +3
Asymmetric processors have emerged as an appealing technology for severely energy-constrained environments, especially in the mobile market where heterogeneity in applications is m…
