Talk Title: Adaptability techniques for QoS and distributed management of MPSoCs
Abstract: Adaptability techniques - With the significant increase in the number of processing elements in NoC-Based MPSoCs, communication becomes, increasingly, a critical resource for performance gains and QoS guarantees. The main gap observed in the NoC-Based MPSoCs literature is the runtime adaptive techniques to meet QoS. In the absence of such techniques, the system user must statically define, for example, the scheduling policy, communication priorities, and the communication switching mode of applications. The goal of this research is to investigate the runtime adaptation of the NoC resources, according to the QoS requirements of each application running in the MPSoC. The present work adopts a NoC architecture with duplicated physical channels, adaptive routing, support to flow priorities and simultaneous packet and circuit switching. The monitoring and adaptation management is performed at the operating system level, ensuring QoS to the monitored applications. The QoS acts in the flow priority and the switching mode. Monitoring and QoS adaptation were implemented in software, resulting in flexibility to apply the techniques to other platforms or include other adaptive techniques, as task migration or DVFS. Applications with latency and throughput deadlines run concurrently with best-effort applications. Results with synthetic and real application reduced in average 60% the latency violations, ensuring smaller jitter and throughput. The execution time of applications is not penalized applying the proposed QoS adaptation methods.
Distributed Management - Scalability is an important issue in large MPSoCs. MPSoCs may execute several applications in parallel, with dynamic workload, and tight QoS constraints. Thus, the MPSoC management must be distributed to cope with such constraints. This talk presents a distributed resource management in NoC-Based MPSoC, using a clustering method, enabling the modification of the cluster size at runtime. This work addresses the following distributed techniques: task mapping, monitoring and task migration. Results show an important reduction in the total execution time of applications, reduced number of hops between tasks (smaller communication energy), and a reclustering method through monitoring and task migration.
Biography: Fernando Moraes received the Electrical Engineering and M.Sc. degrees from the Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, Brazil, in 1987 and 1990, respectively. In 1994 he received the Ph.D. degree from the Laboratoire d ÌInformatique, Robotique et Microélectronique de Montpellier (LIRMM), France. He is currently at PUCRS. From 1998 to 2000 he joined the LIRMM as an Invited Professor for 3 months each year. He has authored and co-authored 24 peer refereed journal articles in the field of VLSI design, comprising the development of networks on chip and telecommunication circuits. One of these articles, HERMES: an Infrastructure for Low Area Overhead Packet-switching Networks on Chip, is cited by more than 500 other papers. He has also authored and co-authored more than 180 conference papers on these topics. He has advised 23 MsC, advised 4 PhD and co-advised 3 PhD works. His primary research interests include Microelectronics, FPGAs, reconfigurable architectures, NoCs (networks on chip) and MPSoCs (multiprocessor system on chip). SBC, SBMICRO and IEEE Senior Member.

NL Seminar- Multi-site genetic analysis of the brain’s white matter: ENIGMA-DTI

Speaker: Neda Jahanshad, (USC/ISI)
Talk Title: Multi-site genetic analysis of the brainâs white matter: ENIGMA-DTI
Series: Natural Language Seminar
Abstract: The functioning regions of the brain are connected through a complex network of fibers, described by the brainâs white matter. Non-invasive imaging using MRI-based diffusion imaging can help capture important characteristics of the connections by describing the strength and directionality profile of water diffusion along white matter fibers. Variability in these connections have been noted in many neurological, degenerative, and psychiatric disorders where ultimately information transfer from on brain region to the other may be weakened or completely compromised. To discover genetic risk factors for altered connectivity and common genetic variants which put the brain at subtle risk for weakened connections, we find power in sample size and pool multiple datasets from around the world to determine common effects in all populations. However, there is no standard method for acquiring diffusion images and standardizing measures across datasets is an ongoing challenge. The Enhancing Neuro Imaging Genetics through Meta Analysis group on Diffusion Tensor Imaging has established a set of basic protocols to overcome a portion of these challenges, which I will describe, along with works-in-progress to tackle additional obstacles to reveal critical details of the brains network.
Biography: Neda Jahanshad is an assistant professor of Neurology at USC in the Imaging Genetics Center at ISI. She received her PhD in Biomedical Engineering at UCLA in 2012 where she worked on optimizing diffusion imaging protocols to map structural brain connections in large populations. She has since extended the work to explore methods of pooling such imaging data from across the world and determine genetic and environmental contributions to the connectivity of the brain and determine how these effects vary across the lifespan. She is coordinating one of the largest studies of the brain's white matter through the ENIGMA Consortium http://enigma.ini.usc.edu.
