Accelerating the SRP-PHAT algorithm on multi and many-core platforms using OpenCL

BADÍA CONTELLES, JOSÉ MANUEL; Belloch Rodríguez, José Antonio; Cobos Serrano, Máximo; IGUAL PEÑA, FRANCISCO DANIEL; Quintana-Ortí, Enrique S. (Springer-Verlag, 2019-03)

[EN] The Steered Response Power with Phase Transform (SRP-PHAT) algorithm is a well-known method for sound source localization due to its robust performance in noisy and reverberant environments. This algorithm is used in ...
Algorithm 1039: Automatic Generators for a Family of Matrix Multiplication Routines with Apache TVM

Alaejos-López, Guillermo; Castelló, Adrián; Alonso-Jordá, Pedro; Igual, Francisco D.; Martínez, Héctor; Quintana-Ortí, Enrique S. (Association for Computing Machinery, 2024-03)
Low precision matrix multiplication for efficient deep learning in NVIDIA Carmel processors

San Juan-Sebastian, Pablo; Rodríguez-Sánchez, Rafael; Igual, Francisco D.; Alonso-Jordá, Pedro; Quintana-Ortí, Enrique S. (Springer-Verlag, 2021-10)

[EN] We introduce a high performance, multi-threaded realization of the gemm kernel for the ARMv8.2 architecture that operates with 16-bit (half precision)/queryKindly check and confirm whether the corresponding author is ...
Micro-kernels for portable and efficient matrix multiplication in deep learning

Alaejos-López, Guillermo; Castelló, Adrián; Martínez, Héctor; Alonso-Jordá, Pedro; Igual, Francisco D.; Quintana-Ortí, Enrique S. (Springer-Verlag, 2023-05)

[EN] We provide a practical demonstration that it is possible to systematically generate a variety of high-performance micro-kernels for the general matrix multiplication (gemm) via generic templates which can be easily ...
Multi-threaded dense linear algebra libraries for low-power asymmetric multicore processors

Catalán, Sandra; Herrero, José R.; Igual Peña, Francisco Daniel; Rodríguez-Sánchez, Rafael; Quintana Ortí, Enrique Salvador; Adeniyi-Jones, Chris (Elsevier, 2018-03)

[EN] 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 ...
Optimized Fundamental Signal Processing Operations for Energy Minimization on Heterogeneous Mobile Devices

Belloch Rodríguez, José Antonio; Badia Contelles, J. M.; Igual Peña, Francisco Daniel; Gonzalez, Alberto; Quintana Ortí, Enrique Salvador (Institute of Electrical and Electronics Engineers, 2017-11)

[EN] Numerous signal processing applications are emerging on both mobile and high-performance computing systems. These applications are subject to responsiveness constraints for user interactivity and, at the same time, ...
Programming parallel dense matrix factorizations and inversion for new-generation NUMA architectures

Catalán, Sandra; Igual, Francisco D.; Herrero, José R.; Rodríguez-Sánchez, Rafael; Quintana-Ortí, Enrique S. (Elsevier, 2023-05)

[EN] We propose a methodology to address the programmability issues derived from the emergence of newgeneration shared-memory NUMA architectures. For this purpose, we employ dense matrix factorizations and matrix inversion ...
Programming parallel dense matrix factorizations with look-ahead and OpenMP

Catalán, Sandra; Castelló, Adrián; Igual, Francisco D.; Rodríguez-Sánchez, Rafael; Quintana Ortí, Enrique Salvador (Springer-Verlag, 2020-03)

[EN] We investigate a parallelization strategy for dense matrix factorization (DMF) algorithms, using OpenMP, that departs from the legacy (or conventional) solution, which simply extracts concurrency from a multi-threaded ...
