Speaker: 
Joe Schoonover
Speaker Description: 
Dr. Joseph Schoonover holds degrees in Applied Mathematics, Physics, and Geophysical Fluid Dynamics from Florida State University. His graduate studies focused on Gulf Stream separation dynamics and high order methods for computational fluid dynamics. After graduating from FSU, he held a post-doc position at the Center for Non-Linear Studies at Los Alamos National Laboratory. This is where his interest in GPU acceleration was born through mentorship activities at the Parallel Computing Summer Research Internship. After leaving CNLS and LANL, Joe became an associate scientist at CU Boulder to work at NOAA's Space Weather Prediction Center to accelerate the operational WAM-IPE code for modeling ionosphere phenomena. Joe has since moved on to a startup company, Fluid Numerics, founded with Guy Thorsby and Elizabeth Simons, that aims to help domain scientists and software developers leverage the latest compute technologies and cloud computing platforms for high performance computing.

This talk will focus on the set of features available in MVAPICH2 and MVAPICH2-GDR MPI libraries to exploit overlap of computation and communication on modern clusters. Sample features will include: job start-up, point-to- point operations, RMA operations, kernel-based collectives, and non-blocking collectives (with and without core- direct support). For MVAPICH2-GDR, we will additionally focus on the use of GPU Direct RDMA, kernel-based reduction and datatype operations. Performance benefits of these features will be presented.

He has published over 400 papers in the area of high-end computing and networking. The MVAPICH2 (High Performance MPI and PGAS over InfiniBand, Omni-Path, iWARP and RoCE) libraries, designed and developed by his research group (http://mvapich.cse.ohio-state.edu), are currently being used by more than 2,875 organizations worldwide (in 86 countries). More than 451,000 downloads of this software have taken place from the project's site. This software is empowering several InfiniBand clusters (including the 1 st , 9 th , 12 th , 17 th , and 48 th ranked ones) in the TOP500 list. The RDMA packages for Apache Spark, Apache Hadoop and Memcached together with OSU HiBD benchmarks from his group (http://hibd.cse.ohio-state.edu) are also publicly available. These libraries are currently being used by more than 275 organizations in 34 countries. More than 25,300 downloads of these libraries have taken place. A high-performance and scalable version of the Caffe framework is available from https://hidl.cse.ohio-state.edu. Prof. Panda is an IEEE Fellow.

Keynote: Designing HPC, Big Data, Deep Learning, and Cloud Middleware for Exascale Systems: Challenges and Opportunities

Date and Time: 
Tuesday 2018 Apr 3rd
Location: 
CG Auditorium
Speaker: 
DK Panda

This talk will focus on challenges and opportunities in designing HPC, Big Data, Deep Learning, and HPC Cloud middleware for Exascale systems with millions of processors and accelerators. For the HPC domain, we will discuss about the challenges in designing runtime environments for MPI+X (PGAS - OpenSHMEM/UPC/CAF/UPC++, OpenMP, and CUDA) programming models by taking into account support for multi-core systems (KNL and OpenPower), high-performance networks, GPGPUs (including GPUDirect RDMA), and energy-awareness.

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.
