Performance improvement of the triangular matrix product in commodity clusters Santamaría Valenzuela, María Inmaculada Carratalá Sáez, Rocío Torres de la Sierra, Yuri Llanos Ferraris, Diego Rafael González Escribano, Arturo Informática There are many works devoted to improving the matrix product computation, as it is used in a wide variety of scientific applications arising from many different fields. In this work, we propose alternative data distribution policies and communication patterns to reduce the elapsed time when computing triangular matrix products in distributed memory environments. In particular, we focus on commodity clusters, where the number of nodes is limited, proposing alternatives to traditional approaches in order to improve this operation’s performance. Our proposal overcomes the performance results associated with the state-of-the-art libraries, such as ScaLAPACK and SLATE, offering execution times that are up to 30% faster. 2024-09-15T08:52:24Z 2024-09-15T08:52:24Z 2024 info:eu-repo/semantics/article Performance improvement of the triangular matrix product in commodity clusters, I.
