A task-based data-flow methodology for programming heterogeneous systems with multiple accelerator APIs

Aleix Boné, Alejandro Aguirre, David Álvarez +2

Heterogeneous nodes that combine multi-core CPUs with diverse accelerators are rapidly becoming the norm in both high-performance computing (HPC) and AI infrastructures. Exploiting…

Rethinking Thread Scheduling under Oversubscription: A User-Space Framework for Coordinating Multi-runtime and Multi-process Workloads

Aleix Roca, Vicenç Beltran

The convergence of high-performance computing (HPC) and artificial intelligence (AI) is driving the emergence of increasingly complex parallel applications and workloads. These wor…

Extending the OmpSs-2 Programming Model for Hybrid Quantum-Classical Programming

Philip Döbler, David Álvarez, Lucas J. Menger +3

The OmpSs-2 programming model is used in HPC programs to parallelize code and offload code to accelerators. In this work, we extend the offloading capability to quantum computers.…

Distributed and heterogeneous tensor-vector contraction algorithms for high performance computing

Pedro J. Martinez-Ferrer, Albert-Jan Yzelman, Vicenç Beltran

The tensor-vector contraction (TVC) is the most memory-bound operation of its class and a core component of the higher-order power method (HOPM). This paper brings distributed-memo…

Improving the performance of classical linear algebra iterative methods via hybrid parallelism

Pedro J. Martinez-Ferrer, Tufan Arslan, Vicenç Beltran

We propose fork-join and task-based hybrid implementations of four classical linear algebra iterative methods (Jacobi, Gauss-Seidel, conjugate gradient and biconjugate gradient sta…
