Have you ever wondered how to reduce scientific data size for storing, handling, and transmitting content? The answer is lossy compression! It’s becoming an essential tool in the efforts to manage and understand the imposing volumes of data that will be produced by exascale simulations and experiments.

This week we encourage you to attend Ben Whitney’s seminar on Feb 18, 2021 at 16:00 CET about “MGARD: Hierarchical Compression of Scientific Data”. Be sure to register here.

Ben Whitney is a postdoc in the Computer Science and Mathematics Division at Oak Ridge National Laboratory. He focuses on compression methods for scientific data and scientific software development.

One of the project he is currently working on is FASTMath, a project which uses scalable mathematical algorithms and software tools for reliable simulation of complex physical phenomena and collaborates with application scientists to ensure the usefulness and applicability of FASTMath technologies.

Ben, during his talk, will share an introduction to MGARD (MultiGrid Adaptive Reduction of Data) which is one of a new generation of scientific data compressors aiming to win the trust of domain scientists with rigorous mathematical underpinnings and guaranteed error bounds.

His presentation will start with the hierarchical decomposition algorithm comprising the core of the method and its ties to the theories of finite element methods, multigrid solvers, and wavelet analysis. He will then discuss quantization techniques enabling bounds on the compression error as measured both in the original data and in quantities of interest computed from the data.

At the end of his seminar, Ben will treat us with a variety of numerical examples and a demonstration of the use of MGARD’s publically available implementation.

Stay in touch with the HPC community by joining our monthly seminars. Each month we invite a bright scientific minds to talk about their current projects during Virtual ICM Seminars in Computer and Computational Science.

About Virtual ICM Seminars
Virtual ICM Seminars in Computer and Computational Science are a continuation of the Supercomputing Frontiers Europe conference, which took place virtually in March 2020 and will be back with the new HPC trends to explore in the summer 2021.

Dates to remember:

  • Supercomputing Frontiers Europe 2021 Conference: July 19-23, 2021
  • Call for Paper deadline: May 16, 2021

Worldwide Open Science online meetings in HPC, Artificial Intelligence, Quantum Computing, BigData, IoT, computer and data networks are a place to meet and discuss with such personalities as Hiroaki Kitano (Systems Biology Institute, Tokyo / Sony Computer Science Laboratories), Stephen Wolfram (Founder & CEO, Wolfram Research), Alan Edelman (MIT), Aneta Afelt (ICM University od Warsaw, Espace-DEV, IRD Montpellier France), Simon Mutch (University of Melbourne) or Scott Aaronson (University of Texas at Austin).

For the listing of all ICM seminars please check this link with recordings.

Since March 2020, over 2400 people have participated in virtual meetings organized by ICM (SCFE + 14 seminars) from almost all the time zones. The https://supercomputingfrontiers.eu/ website with access to the SCFE and seminars’ recordings, has been viewed by more than 15k visitors from 122 countries.

The organizer of meetings with outstanding scientists is the Interdisciplinary Centre for Mathematical and Computational Modelling (ICM), University of Warsaw.
