Wes Bethel
Group Leader, Visualization

 

Wes is a Senior Computer Scientist at Lawrence Berkeley National
Laboratory, where he is a researcher and technical manager of
research and production programs in visualization and analytics. 
His research interests include architectures for  high performance 
visual data analysis,  computer graphics, and remote/distributed
visualization.
He was the Coordinating Principal Investigator for DOE's Scientific
Discovery through Advanced Computing (SciDAC)'s Visualization and
Analytics Center for Enabling Technologies, which produced production-quality,
petascale-capable visual data analysis software infrastructure, and
collaborated with several different science application domains to apply it
to some of the world's most challenging scientific data understanding
problems.

 

Wes Bethel, a senior computer scientist, is the Group Lead for the Visualization Group. He earned a B.S. and an M.S. in computer science from the University of Tulsa in 1984 and 1986, and a Ph.D. in computer science from UC Davis in 2010. Bethel and his team conduct applied research and development on techniques and tools for enabling scientific knowledge discovery in some of the world's largest collections of scientific data generated by computational models and simulations. This work lies at the nexus of data management, data analysis, scientific visualization, and high performance computing. He was the Coordinating Principal Investigator for the SciDAC Visualization and Analytics Center for Enabling Technology (VACET) which made production-quality, petascale-capable visualization a reality at DOE supercomputing facilities, and has produced software tools in use by a worldwide scientific community in disciplines ranging from high energy physics to climate modeling. His research interests include software architecture, high performance computing, scientific and information visualization, and computer graphics. He is an ACM Distinguished Scientist.

Kesheng Wu, Wes Bethel, Ming Gu, David, Oliver Rubel, "A Big Data Approach to Analyzing Market Volatility", Algorithmic Finance (2013), 2:3-4, 241-267, 2013, LBNL LBNL-6382E, doi: 10.3233/AF-13030

Understanding the microstructure of the financial market requires the processing of a vast amount of data related to individual trades, and sometimes even multiple levels of quotes. Analyzing such a large volume of data requires tremendous computing power that is not easily available to financial academics and regulators. Fortunately, public funded High Performance Computing (HPC) power is widely available at the National Laboratories in the US. In this paper we demonstrate that the HPC resource and the techniques for data-intensive sciences can be used to greatly accelerate the computation of an early warning indicator called Volume-synchronized Probability of Informed trading (VPIN). The test data used in this study contains five and a half year's worth of trading data for about 100 most liquid futures contracts, includes about 3 billion trades, and takes 140GB as text files. By using (1) a more efficient file format for storing the trading records, (2) more effective data structures and algorithms, and (3) parallelizing the computations, we are able to explore 16,000 different ways of computing VPIN in less than 20 hours on a 32-core IBM DataPlex machine. Our test demonstrates that a modest computer is sufficient to monitor a vast number of trading activities in real-time -- an ability that could be valuable to regulators.

Our test results also confirm that VPIN is a strong predictor of liquidity-induced volatility. With appropriate parameter choices, the false positive rates are about 7% averaged over all the futures contracts in the test data set. More specifically, when VPIN values rise above a threshold (CDF > 0.99), the volatility in the subsequent time windows is higher than the average in 93% of the cases.

100Gbps networking has finally arrived, and many research and educational in- stitutions have begun to deploy 100Gbps routers and services. ESnet and Internet2 worked together to make 100Gbps networks available to researchers at the Super- computing 2011 conference in Seattle Washington. In this paper, we describe two of the first applications to take advantage of this network. We demonstrate a visu- alization application that enables remotely located scientists to gain insights from large datasets. We also demonstrate climate data movement and analysis over the 100Gbps network. We describe a number of application design issues and host tuning strategies necessary for enabling applications to scale to 100Gbps rates.

We present TECA, a parallel toolkit for detecting extreme events in large climate datasets. Modern climate datasets expose parallelism across a number of dimensions: spatial locations, timesteps and ensemble members. We design TECA to exploit these modes of parallelism and demonstrate a prototype implementation for detecting and tracking three classes of extreme events: tropical cyclones, extra-tropical cyclones and atmospheric rivers. We process a modern TB-sized CAM5 simulation dataset with TECA, and demonstrate good runtime performance for the three case studies.
