It allows the user to discover geo-temporal trends, patterns, and behaviors over very large regions down to specific sites as well as user-defined time periods. This datamining capability has the capacity to make trend analysis possible for users who would have found it otherwise impossible to manually extract the necessary information from a large database and/or a merged collection from multiple data sources. Although the TIMECOP system was initially tuned to operate on a single large database, it is actually data agnostic and has been modified to serve the needs of other users operating on data from different sources. Users connect either to remote or local TIMECOP servers depending on their needs and restrictions. The database is selected from a pull-down menu and the query options matching the database’s contents are dynamically populated. The user makes their query choices and submits the request. The TIMECOP server passes the query to the respective database and returns a formatted Keyhole Markup Language (KML) file or network link for GoogleEarth to display. Users can examine the data statically or in a movie-like fashion, which allows them to engage in geo-temporal trend analysis. Users may then refine the query parameters and resubmit if necessary. The TIMECOP system can operate under low bandwidth conditions, allowing it to transmits query results via a network link to the user’s GoogleEarth client. Depending on the query, the resulting KML file transmitted is typically in the kB range. TIMECOP users can further modify their queries to limit the number of results returned if they are in a low bandwidth environment.","PeriodicalId":268639,"journal":{"name":"2009 DoD High Performance Computing Modernization Program Users Group Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129453805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important then to consider the appropriateness of architectures with respect to applications to make the most efficient use of available resources. However, the number of applications currently used on systems within the High Performance Computing Modernization Program (HPCMP) is very large. This paper, therefore, focuses solely on codes within the HPCMP Technology Insertion 2009 (TI-09) Applications Benchmarking Suite. These codes include Adaptive Mesh Refinement (AMR), Air Vehicles Unstructured Solver (AVUS), CTH, General Atomic and Molecular Electronic Structure System (GAMESS), HYbrid Coordinate Ocean Model (HYCOM), Improved Concurrent Electromagnetic Particle In Cell (ICEPIC), and Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS). This paper evaluates the parallel performance-per-processor of each of these seven codes on major systems within the Program. This, in turn, can guide users and developers in selecting appropriate architectures for each code.","PeriodicalId":268639,"journal":{"name":"2009 DoD High Performance Computing Modernization Program Users Group Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126115580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several scenarios are investigated, all with waves that are individually statically stable (Ri≥0.25). Nevertheless, turbulence outbreaks are observed as the periodic motion of the larger GW induces a parametric instability in the shorter wavelength fine structure wave, and the coupling produces a massive instability response at multiple scales, yielding a layering of the potential temperature field resembling \"sheet and layer\" structures observed in the atmosphere and oceans. Such interactions among large-scale GWs and fine structure due to small-scale inertia-GWs or superposed regions of decaying or fossil turbulence events are likely ubiquitous throughout the atmosphere and may account for sporadic bursts of turbulence and its persistence in regions of high apparent static stability. The implications for these new results are discussed for our probabilistic turbulence forecasting methods.","PeriodicalId":268639,"journal":{"name":"2009 DoD High Performance Computing Modernization Program Users Group Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122587626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the increasing domain size and resolution needs of the modeling applications, it is no longer feasible to execute the pre- and post-processing of the models, such as mesh generation, boundary condition assignment, and visualization, on a single-processor desktop computer. Thus, a cross-platform suite of tools, the Computational Model Builder (CMB), is being developed to allow modelers to create scenes, generate solids from the scenes, and assign boundary conditions and materials on the solids. This greatly reduces the memory footprint of the problem from that required for manipulation of a full three-dimensional mesh, allowing pre- and postprocessing to be performed easily on a desktop. The tagged geometry can then be sent to HPC machines for mesh generation. This paper will discuss the requirements and design decisions for the CMB framework.","PeriodicalId":268639,"journal":{"name":"2009 DoD High Performance Computing Modernization Program Users Group Conference","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115041066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The biological function of a protein is inextricably linked to its three-dimensional (3D) atomic structure. Traditional structure determination methods, such as X-ray and nuclear magnetic resonance techniques, are time-consuming, expensive, and infeasible for the millions of proteins that have been sequenced so far from various organisms. Alternatively, computational structure prediction methods provide a faster and more cost-effective, albeit approximate, alternative to experimental structure determination. We present a high-throughput protein structure prediction pipeline (dubbed “PSPP”), which given input protein sequences infers their 3D atomic structures. The pipeline was designed to be used with high performance computing clusters and to scale with the number of processors. The pipeline encompasses a core Perl module, a parallel job manager, and a Web browser graphical user interface accessible at our Website (www.bhsai.org). The software is currently installed at the Department of Defense (DoD) Maui High Performance Computing Center, and it is available for download along with its associated databases from our site. Currently, DoD scientists are using the pipeline in basic science and drug and vaccine development projects.","PeriodicalId":268639,"journal":{"name":"2009 DoD High Performance Computing Modernization Program Users Group Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132273113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These tools are used to build, test, and package C/C++ and FORTRAN software in a cross platform manner. By using CMake, a software project can be built just as easily on a Windows PC as on a Cray XT5 super computer. In addition, CMake’s CTest facility can test and then populate the testing dashboard CDash (www.cdash.org), which is a web-based tool used to monitor and display the “health” of a software system. In combination with CTest, CDash provides a continuous integration testing system. Finally, CPack can be used to package and deploy software across multiple computing platforms. This paper will describe these tools, how they are used in the software process, and provide specific application of their usage in support of Multi-Scale Reactive Modeling (MSRM) and the Mobile Network Modeling (MNM) High Performance Computing Software Applications Institute. The tools described in this paper are open source and available to any high performance computing (HPC) project. The paper will provide a high level overview of the CMake tools with enough specifics to enable any HPC development effort to begin working with them. We will also describe how these tools and the associated software process provide the computational infrastructure required to rapidly develop next generation HPC software.","PeriodicalId":268639,"journal":{"name":"2009 DoD High Performance Computing Modernization Program Users Group Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131382466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
