    Topology-aware distributed graph processing for tightly-coupled clusters

    No full text
    Cloud applications have burgeoned over the last few years, but they are typically written for loosely-coupled clusters such as datacenters. In this thesis we investigate how one can run cloud applications in tightly-coupled clusters and network topologies, namely super-computers. Specifically, we look at a class of distributed machine learning systems called distributed graph processing systems, and run them on NCSA Blue Waters. Partitioning the graph is key to achieving performance in distributed graph processing systems. We present new topology-aware partitioning techniques that better exploit the structure of the network topologies in supercomputers. Compared to existing work, our new Restricted Oblivious and Grid Centroid partitioning approaches produce 25-33% improvement in makespan, along with a sizable reduction in network traffic. We also discuss optimizations such as smart network buffers that further amplify the improvement. To help operators select the best graph partitioning technique, we culminate our experimental results into a decision tree.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-05-01The student, Mayank Bhatt, accepted the attached license on 2018-04-23 at 17:13.The student, Mayank Bhatt, submitted this Thesis for approval on 2018-04-23 at 17:20.This Thesis was approved for publication on 2018-04-24 at 15:21.DSpace SAF Submission Ingestion Package generated from Vireo submission #12435 on 2018-08-31 at 17:21:19Made available in DSpace on 2018-09-04T20:36:52Z (GMT).

    The Dementia Dilemma in India: Addressing the Care Challenges with a Layered Interventional Model (LIM)

    No full text
    This project presents a literature review focused on the growing public health challenge of dementia in India. With the aging population increasing rapidly, the burden of dementia-related care is expected to intensify in coming decades. The review examines existing research, health system gaps, and sociocultural challenges related to dementia care across urban and rural settings. The core contribution of this work is a proposed layered interventional model designed to strengthen dementia care through a combination of community-based services, caregiver support, primary health integration, and policy-level reforms. The goal of this project is to: Highlight critical gaps in dementia care infrastructure and awareness Synthesize research on existing care models and interventions Propose a strategic, layered approach to improve dementia outcomes in India.

    The Physiological Roles of Rhopr-kinins and the Molecular Characterization of their Gene in the Blood-gorging Insect, Rhodnius prolixus

    No full text
    The dramatic feeding-related activities of the Chagas' disease vector, Rhodnius prolixus are under neurohormonal regulation of serotonin and various neuropeptides. One such family of neuropeptides, the insect kinins, possesses diuretic, digestive and myotropic activities in many insects. In R. prolixus, they co-localize with the corticotropin-releasing factor (CRF)-like diuretic hormone (DH) in neurosecretory cell bodies and their abdominal neurohaemal sites. Additionally, kinins are present in endocrine cells of the midgut and are known to stimulate hindgut and midgut contractions. Through the experimentation presented in this dissertation, the cloning and spatial expression of the R. prolixus kinin (Rhopr-kinin) transcript is described. Physiological bioassays demonstrate the myostimulatory effects of selected Rhopr-kinin peptides and also illustrate the augmented responses of hindgut contractions to co-application of Rhopr-kinin and Rhopr-CRF/DH. The irreversible effects of two synthetic kinin analogs on the hindgut relative to the native kinins also exhibit the prospective biotechnological significance of this study.MAS

    Background: Second-hand smoke (SHS) has enormous adverse health impacts with grave health implications for the next generation. Section 4 of Indian legislation, Cigarettes and Other Tobacco Products Act, prohibits smoking at public places, thus protecting people from SHS. Objective: The objective of present study was to assess the exposure to SHS at home and working areas in Punjab, India. Methods: The present cross-sectional study was conducted from December 2015 to March 2016. A three-stage sampling technique was used for collecting data from three randomly selected districts representing three major regions of Punjab, India. A sample size of 510 individuals was divided equally into an urban and rural area with proportionate sampling on the basis of subsets of age groups and gender. The questionnaire based on tobacco questions for the survey, a subset of key questions from global adult tobacco survey was used. Results: At home, the odds of exposure to SHS exposure was higher (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 0.6–7.3) in urban area, females, low educational status, and nongovernment employee as compared to their counterparts. At workplace, (OR = 3.9 and 95% CI = 1.11–14.3) SHS exposure was higher in rural area, among males, primary and middle education and nongovernment or self-employed occupation. Conclusion: SHS exposure was low in Punjab, India especially in females as compared to other states of the country. The socio-economic disadvantaged groups and people with low education were more likely to experience exposure to SHS at workplace, which should be targeted to reduce tobacco consumption
