Kevin Jorissen

Prior to joining Amazon Web Services (AWS) Kevin Jorissen worked as an academic research scientist in X-ray and electron spectroscopy and computational materials science. He was the lead developer of the FEFF code. He developed a “Scientific Cloud Computing” platform for high-accuracy calculations of spectroscopy that are too big for a user’s computer system. He organized a planning meeting on policies to professionalize materials science computing. He believes that science will flourish if we can give all researchers access to state-of-the-art computational tools. Jorissen’s current position is business development manager with the Scientific Compute (SC) group of AWS meets that goal by creating cloud-based resources for typical SC workflows – immediately available to any researcher anywhere. The accessibility offered by cloud-based SC becomes increasingly important as non-traditional SC users emerge in applied sciences and sciences that were until very recently not quantitative or data-driven.

ParaView Catalyst Tutorial

As supercomputing moves towards exascale, scientists, engineers and medical researchers will look for efficient and cost effective ways to enable data analysis and visualization for the products of their computational efforts. The ‘exa’ metric prefix stands for quintillion, and the proposed exascale computers would approximately perform as many operations per second as 50 million laptops. Clearly, typical spatial and temporal data reduction techniques employed for post processing will not yield desirable results where reductions of 10e3, 10e6, or 10e9 may still produce petabytes, terabytes or gigabytes of data to transfer or store. Since transferring or storing data may no longer be viable for many simulation applications, data analysis and visualization must now be performed in situ. ParaView Catalyst is an open-source data analysis and visualization library, which aims to reduce IO by tightly coupling simulation, data analysis and visualization codes. This tutorial presented the architecture of ParaView Catalyst and the fundamentals of in situ data analysis and visualization. Attendees learned the basics of using ParaView Catalyst with hands-on exercises. The tutorial featured detailed guidance in implementing C++, Fortran and Python examples. Attendees installed a VirtualBox image from the ‘Download File’ link below for demonstrations and the exercises. Flyer
