3 The VELaSSCo project General information VELaSSCO is a EC funded Project which deals with end-user visualization of huge simulation data (Big Data). 3 years project ( ) By 2020, most crucial simulation results such as those from the aeronautic industry or automotive, will not be able to be stored in a single machine or server. How to store, access, simplify and manipulate billion of records to extract the relevant information? How to represent information in a feasible and flexible way? How to visualise and interactively inspect the huge quantity of information they produce taking into account end-user's needs? Benoit Lange - VELaSSCo - KGT2 - [email protected] - Xi'An 7 May

6 Motivations of the project The simulation data are naturally linked to: High Performance Computing Simulation has already been introduced in Big Data area very traditional supercomputer manufacturers such as SGI companies oriented to massive number of customers such as Amazon, offering very attractive solutions for simulation software vendors (Elastic Compute Cloud, EC2, Simple Storage Service, S3) well-known simulation suites such as Matlab or OpenFOAM (precisely through Amazon services) How Big is the current Simulation Data? Some examples include: weather & climate (400 PB/year, now) nuclear & fusion energy (2PB/time step, now, and 200 PB/time step by 2020) high-energy physics, Materials, Chemistry, Biology, fluid dynamics Benoit Lange - VELaSSCo - KGT2 - [email protected] - Xi'An 7 May

7 Objectives of the project Target data DEM FEM Total size 50 GB à 1 PB 30 GB à 50 TB Partitions 1 à 10,000 Particles / elements 10 million 8 million à 1 billion Time-steps 1 billion 40 à 25,000 Variables per node 10 variables 2-8 scalars, 1-2 vectors,?1 tensor?

8 Objectives of the project Nowadays the huge amount of data provided by the solver in HPC cannot be stored in one single machine, so it is mandatory: Distributed post-processing Distributed visualization Problems if a calculation node fails in HPC. Need a redundancy for the data Big Data The main objective of VELaSSCo project is to build the VELaSSCo Platform, a system that performs distributed post-processing operations and visualization of very large simulations. To address this objective, VELaSSCo brings together Simulation and Big Data. Develop a platform which targeted most of IT system Benoit Lange - VELaSSCo - KGT2 - [email protected] - Xi'An 7 May

9 The VELaSSCo architecture Big Data, what does it mean? Big Data refers to data sets whose size is beyond the ability of typical database software tools to capture, store, manage and analyze. (McKinsey Global Institute) Big Data is the term for a collection of data sets so large and complex that it becomes difficult to process using onhand database management tools or traditional data processing applications.

An innovative approach, adopting big data best practices, to handle large scale simulation data sets that have to be stored on multiple servers. A framework equipped with advanced in-situ processing tools to analyse the output of parallel distributed simulation solvers. An analysis platform to analyse and visualize large-scale data sets interactively. This builds on leading edge graphics hardware. Benoit Lange - VELaSSCo - KGT2 - [email protected] - Xi'An 7 May
