  • CS Colloquium: Sangeetha Abdu Jyothi (University of Illinois at Urbana-Champaign) - Automated Resource Management in Large-Scale Networked Systems

    Tue, Feb 12, 2019 @ 11:00 AM - 12:00 PM

    Speaker: Sangeetha Abdu Jyothi, University of Illinois at Urbana-Champaign

    Talk Title: Automated Resource Management in Large-Scale Networked Systems

    Series: CS Colloquium

    Abstract: Internet applications rely on large-scale networked environments such as the cloud for their backend support. In these multi-tenanted environments, various stakeholders have diverse goals. The objective of the infrastructure provider is to increase revenue by utilizing the resources efficiently. Applications, on the other hand, want to meet their performance requirements at minimal cost. However, estimating the exact amount of resources required to meet the application needs is a difficult task, even for expert users. Easy workarounds employed for tackling this problem, such as resource over-provisioning, negatively impact the goals of the provider, applications, or both.
    In this talk, I will discuss the design of application-aware self-optimizing systems through automated resource management that helps meet the varied goals of the provider and applications in large-scale networked environments. The key steps in closed-loop resource management include learning of application resource needs, efficient scheduling of resources, and adaptation to variations in real time. I will describe how I apply this high-level approach in two distinct environments using (a) Morpheus in enterprise clusters, and (b) Patronus in cellular provider networks with geo-distributed micro data centers. I will also touch upon my related work in application-specific context at the intersection of network scheduling and deep learning. I will conclude with my vision for self-optimizing systems including fully automated clouds and an elastic geo-distributed platform for thousands of micro data centers.

    This lecture satisfies requirements for CSCI 591: Research Colloquium.

    Biography: Sangeetha Abdu Jyothi is a Ph.D. candidate at the University of Illinois at Urbana-Champaign.

    Talk Title: Catalysts and processes for the sustainable production and use of fuels and chemicals

    Abstract: Society has benefitted tremendously from the science and engineering efforts that have brought crucial fuels and chemical products to market at a global-scale based on fossil feedstocks: oil, coal, and natural gas. This includes conventional liquid fuels such as gasoline, diesel, and jet fuel, in addition to many other important products such as plastics (e.g. polyethylene) and fertilizer (i.e. ammonia, NH3). Continuing to use fossil-based resources at such high rates, however, could potentially lead to troubling consequences ahead. This motivates the development of new chemical processes to produce the same kinds of fuels and chemicals that we rely on today, however using renewable energy and sustainable feedstocks instead.

    In this talk we will discuss new processes that employ renewable energy (e.g. wind and solar) to power the production of fuels and chemicals in a sustainable manner. This effort is largely motivated by the dropping costs of renewable electricity, the growing penetration of renewables into energy markets, and the need for storing variable electricity. Central to this theme is an effort to develop catalyst materials and associated processes capable of driving important chemical transformations in a sustainable manner involving renewable energy. Specific examples include the production of hydrogen (H2),1,2 carbon-based products (e.g. hydrocarbons, alcohols),3 and ammonia (NH3) fertilizer.4

    The development of catalysts with appropriate properties can serve as the basis of new, renewable pathways to produce the large-scale fuels and chemicals that could play a major role in reaching sustainability goals for the globe.
