Data-Driven Spectral Prediction for Accelerating Large-Scale Electronic Structure Calculations
Abhiram Badrinarayanan, Davor Davidovic, Edoardo Di Napoli +4
Simulating large molecular systems comprising thousands of atoms requires highly scalable methodologies. While modern Density Functional Theory (DFT) codes exhibit linear scaling,…
QR factorization of ill-conditioned tall-and-skinny matrices on distributed-memory systems
Nenad Mijić, Abhiram Kaushik, Davor Davidović
In this paper we present a novel algorithm developed for computing the QR factorisation of extremely ill-conditioned tall-and-skinny matrices on distributed memory systems. The alg…
ChASE -- A Distributed Hybrid CPU-GPU Eigensolver for Large-scale Hermitian Eigenvalue Problems
Xinzhe Wu, Davor Davidovic, Sebastian Achilles +1
As modern massively parallel clusters are getting larger with beefier compute nodes, traditional parallel eigensolvers, such as direct solvers, struggle keeping the pace with the h…
Accelerating the computation of FLAPW methods on heterogeneous architectures
Davor Davidović, Diego Fabregat-Traver, Markus Höhnerbach +1
Legacy codes in computational science and engineering have been very successful in providing essential functionality to researchers. However, they are not capable of exploiting the…
INDIGO-DataCloud:A data and computing platform to facilitate seamless access to e-infrastructures
DataCloud Collaboration, Davide Salomoni, Isabel Campos +61
This paper describes the achievements of the H2020 project INDIGO-DataCloud. The project has provided e-infrastructures with tools, applications and cloud framework enhancements to…
Hybrid CPU-GPU generation of the Hamiltonian and Overlap matrices in FLAPW methods
Diego Fabregat-Traver, Davor Davidović, Markus Höhnerbach +1
In this paper we focus on the integration of high-performance numerical libraries in ab initio codes and the portability of performance and scalability. The target of our work is F…
Solving Dense Generalized Eigenproblems on Multi-threaded Architectures
José I. Aliaga, Paolo Bientinesi, Davor Davidović +3
We compare two approaches to compute a portion of the spectrum of dense symmetric definite generalized eigenproblems: one is based on the reduction to tridiagonal form, and the oth…
Three-Level Parallel J-Jacobi Algorithms for Hermitian Matrices
Sanja Singer, Sasa Singer, Vedran Novakovic +3
The paper describes several efficient parallel implementations of the one-sided hyperbolic Jacobi-type algorithm for computing eigenvalues and eigenvectors of Hermitian matrices. B…
