Recovery Monitoring of Tsunami Damaged Area using Remote Sensing
On March 11, 2011, Great East Japan Earthquake struck Tohoku Region of Japan. Huge area in the northeast coast of Japan was seriously damages by the magnitude 9.0 earthquake and subsequent tsunami. In late of the year, the author has set up a project for monitoring the recovery of the tsunami damaged area of Miyagi Prefecture by ground survey and satellite image data analysis. Environmental education is another important aspect of this project. The project was funded by Japan Society for the Promotion of Science(JSPS). The first term was from 2012 to 2016, and we are now in the second term which will last until 2021. In this project, we have been monitoring the recovery status of various damaged areas of Miyagi Prefecture by visiting the areas twice a year and comparing multi temporal satellite images. We are also involving students for environmental education. In my talk, various onsite photos and satellite images, which reflect the dramatically recovery of the areas, will be presented. The time series of various satellite images showed how the seriously destroyed paddy fields near the mouth of Kitakami River rapidly recovered by the landfilling. Multi temporal analysis of MODIS NDVI was also very useful for evaluating the recovery status of paddy fields. We cannot stop disasters. Disasters will come suddenly. However, by proper preparation, we may minimize the damages of disasters. Several ways to utilize remote sensing technology for quick disaster monitoring will also be proposed.

The European Open Science Cloud on a global stage
Over the past years, numerous policy makers from around the world have articulated a clear and consistent vision of global Open Science as a driver for enabling a new paradigm of transparent, data-driven science as well as accelerating innovation. In Europe, this vision is being realised through an ambitious programme under the heading of the European Open Science Cloud (EOSC). The EOSC will offer 1.7 million European researchers and 70 million professionals in science, technology, the humanities and social sciences a virtual environment with open and seamless services for storage, management, analysis and re-use of research data, across borders and scientific disciplines by federating existing scientific data infrastructures, currently dispersed across disciplines and the EU Member States. The research communities that EOSC aims to serve span the globe and so EOSC cannot operate in isolation but must find ways to be part of the broader, international open science movement. This presentation will give an update on the status of EOSC and the approaches being considered for how EOSC can engage at a global level.

Recent Trends in HPC Architecture and Random Number Generation in the Exascale Era
The number of nodes/cores of the HPC systems has been increasing rapidly in recent years; some currently available systems are already equipped with more than one million cores. As the degree of parallelism in the system reaches this level, the performance of some of the traditional numerical algorithms need to be re-examined, due to a widening imbalance between the computational capability vs available memory size per core and /or inter-processor communication bandwidth. In this regard, the Monte Carlo Methods (MCMs) possess the following advantageous characteristics:
(1) Very high degree of parallelism exists inherently, where very few information is exchanged across nodes/cores,
(2) Required memory size per node/core can be smaller than some deterministic mesh-based algorithms
(3) Due to statistical nature of MCM algorithms, fault resilience is expected to some extent.
Therefore, we should give more considerations in expanding the application areas of MCMs such as the solution of the elliptic partial differential equations, for example. In order to conduct the Monte Carlo calculations correctly and efficiently, the capability to generate high quality pseudo-random number sequence is crucial. The desirable features are:
(1) Long period of the sequence,
(2) High statistical qualities both with serial and across the multiple sequences,
(3) Fast computation in generating the random number sequences,
(4) Efficient initialization of multiple sequences for millions of cores.
We have been developing the “Multiple Recursive Generators (MRG)” based on the 8-th order full polynomials with a large modulus (2^31-1), which can generate statistically high-quality random number sequences with very long periods(~10^74), and easily implementable jump-ahead scheme for effective parallelization. We have recently reformulated the MRG8 for Intel’s KNL and NVIDIA’s P100 GPU – named MRG8-AVX512 and MRG8-GPU, respectively.
