Optimizing parallel I/O performance of HPC applications
No full textParallel I/O is an essential component of modern High Performance Computing (HPC). Obtaining good I/O performance for a broad range of applications on diverse HPC platforms is a major challenge, in part because of complex inter-dependencies between I/O middleware and hardware. The parallel file system and I/O middleware layers all offer optimization parameters that can, in theory, result in better I/O performance. Unfortunately, the right combination of parameters is highly dependent on the application, HPC platform, and problem size/concurrency. Scientific application developers do not have the time or expertise to take on the substantial burden of identifying good parameters for each problem configuration. They resort to using system defaults, a choice that frequently results in poor I/O performance. We expect this problem to be compounded on exascale class machines, which will likely have a deeper software stack with hierarchically arranged hardware resources.
We present a line of solution to this problem containing an autotuning system for optimizing I/O performance, I/O performance modeling, I/O tuning, I/O kernel generation, and I/O patterns. We demonstrate the value of these solution across platforms, applications, and at scale.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2017-12-01The student, Babak Behzad, accepted the attached license on 2015-11-20 at 13:31.The student, Babak Behzad, submitted this Dissertation for approval on 2015-11-20 at 13:45.This Dissertation was approved for publication on 2015-11-23 at 13:41.DSpace SAF Submission Ingestion Package generated from Vireo submission #8816 on 2016-03-02 at 14:06:01Made available in DSpace on 2016-03-02T20:23:36Z (GMT).

Competition in dual-channel supply chains: The manufacturers' channel selection
No full text© 2020 The Author(s) Innovative selling channels have brought about opportunities as well as challenges for upstream manufacturers. The past few years have witnessed both the success and failure of manufacturers with different channel strategies. To explore the rationale of different channel strategies in various contexts, we develop a model to analyze a manufacturer's channel selection decision among three channel strategies, i.e., a direct-channel strategy, a retail-channel strategy, and a dual-channel strategy consisting of both direct and retail channels. The model rests on the channel differentiation in terms of consumers’ channel preferences and operating costs of retail and direct channels. Specifically, we incorporate the action of a competitor and track down its influence on the focal manufacturer's channel preference. Our research clarifies the role of competition in the market and offers insights into the competitive nature of business in real life. Results show that the manufacturer's channel preference depends not only on the channels’ operating costs and consumers’ channel preferences but also on the competitor's channel strategy. We find that symmetric manufacturers can adopt asymmetric strategies as Nash equilibria and also that there are situations where no Nash equilibrium exists. We characterize the Nash equilibria in the channel selection game based on the exogenous parameters of the model
Experimental Evaluation of Chemical Reactions Involved in Ultrasonic-Assisted Absorption of Bulk CO2
No full textAs the most mature natural gas sweetening process, absorption has always been improved to meet the separation requirement. Recently, ultrasonic irradiation has been proposed as a technique that can intensify CO2 absorption. However, further studies are still required, particularly focusing on the sonochemical effect. Since the influence of the sonochemical effect on the reaction pathway is still debatable, attention must be given to verifying the influence of ultrasonic irradiation on the chemical reactions of CO2 absorption. Hence, this work aims to evaluate the influence of OH˙ radicals generated by the sonochemical effect on the chemical reactions involved during CO2 absorption using promoter-free methyldiethanolamine (MDEA). For the evaluation, various samples under irradiated and non-irradiated conditions are analyzed using the HPLC characterization technique. The results show that the hypothesis of changing the reaction pathway due to the presence of the sonochemical effect is invalid. However, it can accelerate the generation of hydroxyl radicals (OH˙) via water sonolysis. Thus, the origin of sonochemistry in aqueous solutions is defined as water sonolysis. The analysis of the CO2 absorption rate also demonstrates the presence of accelerated chemical reactions (contributed by the OH˙ radicals), which could potentially make the slow kinetic MDEA more practical for industrial application
Prediction of hydrate formation conditions based on the vdWP-type models at high pressures
No full textGas Hydrate Equilibrium Measurement of Methane + Carbon Dioxide + Tetrahydrofuran+ Water System at High CO2 Concentrations
No full textAbstractApplication of gas hydrate in separation of carbon dioxide (CO2) form nitrogen in Carbon Capture and Storage (CCS) chain is recently studied by many researchers. Tetrahydrofuran (THF) is suggested as promoter for this process. The same process can be suggested for separation of CO2 from methane (CH4) for gas treatment and sweetening, especially for high CO2 content mixtures such as landfill gas. The first step in development of such process is understanding of the phase boundary of this mixture at different pressure-temperature condition and gas/liquid composition. In this work, gas hydrate phase boundary of CH4, CO2, THF and water at different pressure from 4.5 to 8.1 MPa is experimentally measured. CO2 mole fraction in gas phase is fixed at 0.7 and THF concentration in the liquid phase set at 0.03 mole fraction. Results show that presence of THF in the mixtures shift the phase boundary to the lower pressure / higher temperature condition. This effect is favorable for industrial applications
Cytokine-mediated FOXO3a phosphorylation suppresses FasL expression in hemopoietic cell lines: Investigations of the role of Fas in apoptosis due to cytokine starvation
No full textWe have investigated phosphatidylinositol 3-kinase (PI3K)-dependent survival signalling pathways using several cytokines in three different hemopoietic cell lines, MC/9, FDC-P1, and TF-1. Cytokines caused PI3K- and PKB-dependent phosphorylation of FOXO3a (previously known as FKHRL1) at three distinct sites. Following cytokine withdrawal or PI3K inhibition, both of which are known to lead to apoptosis, there was a loss of FOXO3a phosphorylation, and a resulting increase in forkhead transcriptional activity, along with increased expression of Fas Ligand (FasL), which could be detected at the cell surface. Concurrently, an increase in cell surface expression of Fas was also detected. Despite the presence of both FasL and Fas, there was no detectable evidence that activation of Fas-mediated apoptotic events was contributing to apoptosis resulting from cytokine starvation or inhibition of PI3K activity. Thus, inhibition of FOXO3a activity is mediated by the PI3K–PKB pathway, but regulation of FasL is not the primary means by which cell survival is regulated in cytokine-dependent hemopoietic cells. We were also able to confirm increased expression of known FOXO3a targets, Bim and p27kip1. Together, these results support the conclusion that mitochondrial-mediated signals play the major role in apoptosis of hemopoietic cells due to loss of cytokine signalling.
