Probabilistic forecasting for weather prediction

Date and Time: 
Monday 2018 Apr 2nd
Location: 
CG Auditorium
Speaker: 
Luca Delle Monache

Probabilistic forecasts provide a distribution of the potential future states of the atmosphere. There are two main methods to generate probabilistic forecasts: one is to run multiple model realizations or multiple models with initial perturbations, and the second is to use analogs. The Analog Ensemble (AnEn) algorithm discussed in this presentation generates probabilistic predictions using a single deterministic NWP, a set of past forecast predictions, and their corresponding observations. The AnEn technique compensates for the model bias by taking past errors into account.

Speaker Description: 

Luca Delle Monache is the Deputy Director of the National Security Applications Program at NCAR. Dr. Delle Monache has research interests in applied mathematics, atmospheric chemistry, meteorology, probabilistic forecasting, applied research, and interdisciplinary research.

SeedMe (Stream, Encode, Explore and Disseminate My Experiments) project to support scientific data-sharing and data management

Date and Time: 
Tuesday 2018 Apr 3rd
Location: 
CG Auditorium
Speaker: 
Amit Chourasia

The need for data sharing and rapid data access has become central with the rise of collaborative research in many disciplines. For the general public, several file sharing products are available that post and share files using web browsers. But for science data and research use, these products are not well suited. While consumer products get by with manual user interfaces to add and remove a few shared files, this is not practical for sharing large numbers of science data files, like those generated during and after large-scale computation.

Speaker Description: 

Amit Chourasia is a Sr. Visualization Scientist at the San Diego Supercomputer Center, UC San Diego where he leads the Visualization Group. His work is focused on leading the research, development and application of software tools and techniques for visualization. Result and data sharing are also at a forefront of his interests, to this end he has developed a web based cloud infrastructure to enable this important and at times critical gap in scientific process via the SeedMe project.

Performance modeling results of Higher Order Symmetric Schemes

Date and Time: 
Tuesday 2018 Apr 3rd
Location: 
CG Auditorium
Speaker: 
Jack Ogaja

Performance modeling results of Higher Order Symmetric Schemes in a Limited Area model, COSMO, show that the increased stencil width associated with the schemes has insignificant impact on the computational costs when applied at climate scales. The computing time for longer time integration of the model equations is however affected by additional operations necessary for the symmetric conservative fourth order scheme.

Decoupled MapReduce using MPI one-sided communication

Date and Time: 
Tuesday 2018 Apr 3rd
Location: 
CG Auditorium
Speaker: 
Sergio Rivas-Gomez

In this talk, we present an on-going work that proposes the integration of MPI one-sided communication in MapReduce frameworks. By using a decoupled strategy, we aim to overlap computations with communications during the Map and Reduce phases. Hence, we effectively increase the performance in situations where the workload is unexpectedly unbalanced. In addition, we present a novel mechanism for decentralized job-stealing, which enables MPI processes to obtain ownership of input datasets.

Speaker Description: 

Sergio Rivas-Gomez is a Ph.D. student in High-Performance Computing at KTH Royal Institute of Technology (Sweden) under the supervision of Erwin Laure and Stefano Markidis. His research focuses on the integration of unified programming interfaces that enable new mechanisms for handling high-performance I/O on Exascale. Sergio is also part of the SAGE Project, one of the leading Exascale efforts of the European Union.
