Fields from health care to social media benefit from leveraging big data, and there are many parallel world-class research efforts underway here at U of T to address the challenges. This one-day workshop unites investigators from across the university, who share the common goal of tackling high-impact societal problems in need of multi-faceted solutions. Discovering new and valuable approaches to these complex issues demands cross-disciplinary collaboration between fields ranging from engineering to astrophysics, mathematics to public health.
Faculty and graduate students are invited to join us on Thursday, July 3, 2014 at the Bahen Centre for Information Technology, room 1130. Attend the talks or submit posters for presentation.

Abstract: This talk will provide an overview of the work that we have been conducting over the last ten years on collecting, storing and analyzing social media data. I will present an overview of the BlogScope system an early social media analytics platform, Grapevine a social news system and Peckalytics. In each case we will outline the main challenges and technology we developed to address them. These include both algorithmic challenges as well as system and design optimizations that enabled us to support real-time analysis at scale.

Abstract: I will provide an overview of the BrainCODE neuroscience data repository being developed for the Ontario Brain Institute (OBI) by a consortium of Ontario research groups including the Ontario Cancer Biomarker Network, Rotman Research Institute (RRI), Baycrest, the Electronic Health Information Laboratory, Ottawa, and the High Performance Computing Virtual Laboratory, Kingston. Within BrainCODE we are developing both standardized processing and analysis pipelines, without restricting the broader range of tools that researchers may wish to use. I will illustrate such pipelines with the specific goal of optimizing processing and analysis of BOLD fMRI data to discover reliable brain networks that support task performance, and are linked with behavioral responses.

Abstract: Neuroscience applications process large data sets consisting in functional Magnetic Resonance Imaging (fMRI) brain images, through a set of pipelined parametrized operations. Overall, a brain model is built for determining correlations across brain images of several patients (subjects) with given accuracy and reproducibility optimizations goals. While the application may process large amounts of data, the operations performed are also compute and memory intensive e.g., Eigen Value Decomposition. We study methods for scheduling tasks efficiently as well as optimizing the task selection for the purposes of reducing the overall run-time and allowing interactive modelling. Our platform is a Cloud infrastructure we have built ourselves on top of a heterogeneous cluster of multi-core CPU and GPU components.

Abstract: Implementing computations in hardware vs. software can provide orders of magnitude improvement in computational speed and energy efficiency. However, hardware design is challenging compared to writing software, and hardware expertise is comparatively rare. In this talk, we will describe a high-level synthesis tool, called LegUp, being developed at the University of Toronto. LegUp accepts a standard C soft program as input and automatically compiles the program to a hybrid architecture containing a processor and custom hardware accelerators. LegUp, along with a set of benchmark C programs, is open source and freely downloadable, providing a powerful platform that can be leveraged for new research on a wide range of high-level synthesis topics. The tool has been downloaded by over 1000 groups from around the world since its initial release in March 2011. The talk will overview LegUp’s current capabilities, as well as current research directions underway.
Bio: Jason Anderson received the B.Sc. degree in computer engineering from the University of Manitoba, and the M.A.Sc. and Ph.D. degrees in electrical and computer engineering (ECE) from the University of Toronto (U of T). He is an Associate Professor with the Department of ECE, U of T. From 1997-2008, he was with the field-programmable gate array (FPGA) implementation tools group at Xilinx, Inc., in San Jose, CA, and Toronto, ON. From 2005 to 2008, he managed groups at Xilinx focused on placement, routing, and strategic projects. He became a Principal Engineer at Xilinx in 2007. He joined the ECE Department at Toronto in 2008. He has received five awards for excellence in undergraduate teaching, holds 25 U.S. patents, and has authored over 60 papers in refereed journals and symposia. His research interests include all aspects of computer-aided design (CAD), architecture and circuits for FPGAs.
Abstract: Field-Programmable Gate Arrays (FPGAs) have been used successfully as accelerators for many applications because of the ability to build application-specific engines and memory systems. FPGAs are particularly well-suited to the processing of fine-grain data, pattern matching, streaming data applications, and networking. FPGAs have also been shown to have significant advantages from the power perspective. In this talk, I will present an overview of FPGA capabilities and work we are doing that we believe could be useful in the Big Data field. While we believe there can be significant benefit to using FPGAs in Big Data applications, we lack knowledge about real applications and seek possible collaborations.

Prior to joining UofT in 1988 he was at the Computer Systems Laboratory at Stanford University, Stanford, CA, as a Research Associate, where he was a major contributor to an early RISC microprocessor design called MIPS-X, one of the first microprocessors with an on-chip instruction cache and the root of many concepts used in processors today. His research interests include high performance computer architectures, reconfigurable computing, embedded and application-specific processors, and field-programmable gate array architectures and applications.
