Solving Challenging Numerical Linear Algebra Algorithms Using Multiple GPU Accelerators
Abstract:

See the newest features integrated in MAGMA (Matrix Algebra on GPU and Multicore Architectures) to tackle the multiple GPU-based systems for numerical linear algebra. In this talk, we describe how we leveraged MAGMA to solve existing and new challenging numerical problems on multiple hardware accelerators. Using a hybridization methodology, the new multiGPU-enabled MAGMA is characterized by a representation of linear algebra algorithms as directed acyclic graphs, where nodes correspond to tasks and edges to data dependencies among them, and a dynamic runtime system environment StarPU used to schedule various computational kernels over hybrid architectures of GPUs and homogeneous multicores.
