EXA2PRO-EoCoE joint workshop

Contribution List

1. EXA2PRO framework overview & success stories

Lazaros Papadopoulos (ICCS/NTUA)

2/22/21, 9:30 AM

EXA2PRO

Overview of the EXA2PRO project and EXA2PRO framework

2. EXA2PRO High-level programming interface: SkePU and ComPU

Christoph Kessler (Linköping University)

2/22/21, 10:00 AM

EXA2PRO

We shortly present the main concepts of the EXA2PRO high-level programming model: SkePU skeletons (i.e., generic C++ program constructs with multiple backends supporting heterogeneous systems and clusters), multi-variant software components with explicit metadata annotation, smart data-containers for array-based data types, and the XPDL platform modeling...

3. EXA2PRO Runtime system: StarPU

Samuel Thibault (University of Bordeaux)

2/22/21, 11:15 AM

EXA2PRO

We present the concepts of the EXA2PRO low-level programming model: StarPU task-based programming (https://starpu.gitlabpages.inria.fr/), which provides optimized execution on clusters of heterogeneous platforms. We will start with the basic principles of task-based programming. We will then bring an overview of the set of features and optimizations which are thus made possible at little...

Edouard Audit (CEA)

2/22/21, 2:00 PM

EoCoE

Overview of the EoCoE project

6. EoCoE - FTI - State-of-the-art multi-level checkpointing library

Leonardo Bautista-Gomez (Barcelona Super-Computing Center)

2/22/21, 3:45 PM

EoCoE

Large scale infrastructures for distributed and parallel computing offer thousands of computing nodes to their users to satisfy their computing needs. As the need for massively parallel computing increases in industry and development, cloud infrastructures and computing centers are being forced to increase in size and to transition to new computing technologies. While the advantage for the...

15. Solving large linear systems with parallel solvers designed on top of runtime systems

Florent Pruvost (INRIA)

2/24/21, 2:00 PM

EoCoE

The HiePACS Inria team co-develops linear algebra libraries to solve very large numerical systems on supercomputers. To get good performances whatever the computing machine, these libraries are designed as task-based algorithms and make use of runtime systems such as OpenMP (task), Parsec or...

3.Individual work session
(90min, A. Ernstsson, J. Ahlqvist, C. Kessler)

For this session we expect that participants install or have installed SkePU on some Linux system accessible to them (GPU or cluster architecture is not required). For fast installation we provide a binary x86-64 Linux distribution of SkePU (for ubuntu 18.04...
