PSBLAS 3.6 - Sparse Matrices Computation & Iterative Solvers for HPC

Date: January 20th, 2020

speaker: Fabio Durastante (CNR, Naples, Italy)

abstract: This tutorial will address the basic functionalities of the PSBLAS library for the parallelization of computationally intensive scientific applications.

We will delve into the parallel implementation of iterative solvers for sparse linear systems in a distributed memory paradigm, and look at the routines for multiplying sparse matrices by dense matrices, solving block diagonal systems with triangular diagonal entries, preprocessing sparse matrices, and several additional routines for dense matrix operations.

We will discuss both the direct usage of the library in Fortran2003 and the usage of the C interfaces.

The tutorial will include examples relative to the EoCoE-II application areas, and highlight how the PSBLAS environment can be used to obtain scalable parallel codes.

EoCoE is a European Horizon 2020 funded project of Centre of Excellence in computing applications. It is designed to enhance numerical simulation efficiency in the international context of the High Performance Computing (HPC) challenges. It focusses its application scope towards low carbon energy domains.

To measure solar energy's profound impact, we must contemplate the “carbon footprint” — a metric that quantifies the total greenhouse gas emissions caused by an individual, organization, event, or product. Traditional electricity production contributes heavily to a nation's footprint, with fossil fuels being the predominant energy source. By harnessing solar energy, we offset these emissions and aid in the progressive decline of our collective carbon footprint.

Switching to solar is more than energy change it's a commitment to a future with reduced carbon emissions

Our Role in Solar Advancement

To measure solar energy's profound impact, we must contemplate the “carbon footprint” — a metric that quantifies the total greenhouse gas emissions caused by an individual, organization, event, or product. Traditional electricity production contributes heavily to a nation's footprint, with fossil fuels being the predominant energy source. By harnessing solar energy, we offset these emissions and aid in the progressive decline of our collective carbon footprint.

In the battle against climate change, the shift towards renewable energy sources plays a pivotal role. Among these, solar energy emerges as a beacon of hope and innovation. Positioned as both a clean and inexhaustible source of power, solar energy has shown significant promise in reducing global carbon emissions. Let’s explore how the adoption of solar power is making strides in the journey towards a more sustainable future.

Active participation from both consumers and industries in the solar movement is imperative. It includes transitioning to solar power where feasible, supporting policies that encourage
