McCormick & Baxter site reuse assessment : Final report

128 pp. Bookmarks supplied by UO. Includes figures. Published June, 2001. Captured May 7, 2008.This report relates the progress and recommendations of a reuse assessment project for the McCormick and Baxter site. The City of Portland Bureau of Planning coordinated the project under contract with the U.S. Environmental Protection Agency (EPA). The reuse assessment is one of ten pilot projects being implemented around the country to launch EPA’s Superfund Redevelopment Initiative.

GPU-Accelerated Large-Eddy Simulation of Turbulent Channel Flows

High performance computing clusters that are augmented with cost and power efficient graphics processing unit (GPU) provide new opportunities to broaden the use of large-eddy simulation technique to study high Reynolds number turbulent flows in fluids engineering applications. In this paper, we extend our earlier work on multi-GPU acceleration of an incompressible Navier-Stokes solver to include a large-eddy simulation (LES) capability. In particular, we implement the Lagrangian dynamic subgrid scale model and compare our results against existing direct numerical simulation (DNS) data of a turbulent channel flow at Reτ = 180. Overall, our LES results match fairly well with the DNS data. Our results show that the Reτ = 180 case can be entirely simulated on a single GPU, whereas higher Reynolds cases can benefit from a GPU cluster

Automatic and Portable Mapping of Data Parallel Programs to OpenCL for GPU-Based Heterogeneous Systems

General-purpose GPU-based systems are highly attractive, as they give potentially massive performance at little cost. Realizing such potential is challenging due to the complexity of programming. This article presents a compiler-based approach to automatically generate optimized OpenCL code from data parallel OpenMP programs for GPUs. A key feature of our scheme is that it leverages existing transformations, especially data transformations, to improve performance on GPU architectures and uses automatic machine learning to build a predictive model to determine if it is worthwhile running the OpenCL code on the GPU or OpenMP code on the multicore host. We applied our approach to the entire NAS parallel benchmark suite and evaluated it on distinct GPU-based systems. We achieved average (up to) speedups of 4.51× and 4.20× (143× and 67×) on Core i7/NVIDIA GeForce GTX580 and Core i7/AMD Radeon 7970 platforms, respectively, over a sequential baseline. Our approach achieves, on average, greater than 10× speedups over two state-of-the-art automatic GPU code generators

City of Portland asset status and conditions report

46 pp. Bookmarks supplied by UO. Tables, charts, appendices. Published December, 2006; Director's draft January 1, 2007. Captured August 24, 2009.This is the fourth year of reporting on the status and condition of the City's physical infrastructure. In 2005, the City changed from focusing on a single condition of assets (deteriorating infrastructure) to a more holistic asset management approach. This approach seeks to ensure that the City’s assets are adequate to provide desired levels of service. This report describes the status of built improvements. Land/plants, rights-of-way, and human resources are excluded. [From the document

Infill and redevelopment strategies

116 pagesThe Infill and Redevelopment Strategies project consists of: analyzing the demand for housing and mixed residential/commercial uses and identifying those factors that may be expected to affect demand for such development within the City of Portland; analyzing the capacity of the City of Portland to accommodate such demand; identifying neighborhood characteristics that affect the feasibility of infill and redevelopment; and developing a program of strategies that can be undertaken by citizens, the City, other public agencies and the private sector to promote infill and redevelopment. [From the document]"Funding for the Bureau of Planning's participation in the development of this plan was provided as part of the Portland Office of Transportation funding in addition to the City of Portland's General Fund.

Fire station #1 relocation real estate / economic impact report

105 pp. Bookmarks supplied by UO. Maps, tables, figures, appendices. Published April 13, 2004. Captured February 26, 2009.Based upon the findings presented in this report, if the relocation of Fire Station No. 1 occurs, the introduction of a new state-of-the-art fire station and headquarters, learning center and fire museum should benefit not only those businesses and properties immediately adjacent to the station, but also those in the surrounding neighborhood. The addition of such a facility along with the redevelopment and renovation of the historic Globe Hotel Building, with street-level retail and either upper floor office or residential space, should stimulate improvement of the tenant profile, quality of surrounding land uses, and building conditions in the study area.

Central Gateway redevelopment strategy : Final report

121 pp. Bookmarks supplied by UO. Maps, tables, charts, figures, appendices. Published July, 2007. Captured February 27, 2009.The Central Gateway Redevelopment Strategy was initiated by the Portland Development Commission (PDC) to create a vision and implementation strategy to guide the area's growth and development for the next 15 years.... The strategy is intended to build on previous planning and analysis, refine and update that work, and to ultimately stimulate private investment in Central Gateway. [From the document

Food cartology : Rethinking urban spaces as people places

52 pp. Bookmarks supplied by UO. Maps, charts, tables, figures, forms, appendices, illus. Not dated; most recent activity 2008. Captured May 4, 2009.The Urban Vitality Group (UVG) partnered with the City of Portland, Bureau of Planning to study the effects that food carts have on street vitality and neighborhood livability. The number of food carts within the city seems to be growing, while the City lacks sufficient knowledge about the industry to guide policy. The purpose of the study was to assess the benefits and negative consequences of allowing food carts within the city and to ascertain what economic opportunities may be offered by food carts, especially for low-income and minority entrepreneurs. The findings indicate that food carts have significant community benefits to neighborhood livability by fostering social interactions, walkability, and by providing interim uses for vacant parcels. Additionally, carts provide good employment opportunities for immigrants and low-income individuals to begin their own businesses, although there are significant barriers to continued stability and success.

City of Portland asset status and conditions report

62 pp. Bookmarks supplied by UO. Charts, tables, appendices. Published December, 2008. Captured August 20, 2009.This sixth report on the status and condition of the City's physical infrastructure takes a holistic approach to ensure that the City’s assets are adequate to provide desired levels of service. This report seeks to provide coordinated, integrated, fact-based information about the City of Portland’s physical assets that will enhance a ‘whole-of-city’ approach to asset management (AM). It provides an accounting of the number of assets, replacement value, condition, and unmet funding needs. Information in the report will assist the City's efforts to ensure infrastructure is in good condition and that operation, maintenance, rehabilitation, and development programs are as efficient and effective as possible.
