FOR IMMEDIATE RELEASE
HiCLAS1 Announces AERMOD-HPCS ReleaseDurham, North Carolina, 3rd July, 2007 HiPERiSM Consulting, LLC, (Durham, North Carolina) and AS1MET Services (Blanco, Texas), operating together as the HiCLAS1 joint venture, announced today the availability of AERMOD-HPCS, a High Performance Computing (HPC), single threaded, version of the American Meteorological Society / U.S. EPA Regulatory Model, AERMOD. The current release is for the Microsoft Windows™ Operating System, with a version for Linux planned for later in the year once quality assurance testing is completed. As of December 2006, AERMOD became the preferred model for regulatory use for transport distances less than 50 kilometers. AERMOD is now in widespread use, but suffers from computational inefficiencies in performance with the U.S. EPA release for commodity platforms. It is in response to this circumstance that HiCLAS1 offers AERMOD-HPCS. This new version has been demonstrated to execute as much as 2 to 3 times faster than the U.S. EPA release for the same data (for details see HPC-2007-1). The causes of performance limitations in the U.S. EPA version of AERMOD code have been identified and restructured by HiCLAS1 through proprietary performance enhancements to better match commodity architectures. Most importantly, all of this code restructuring was done without modifying any of the underlying science. Thus AERMOD-HPCS is simply a computationally-enhanced version of AERMOD. George Delic, Ph.D., CEO of HiPERiSM Consulting, LLC, said that “with this release of v1.8 we have taken the first step up the performance curve for AERMOD. But we are already at work on the next steps. So end-users of AERMOD should expect further performance enhancements in the near-term for AERMOD-HPCS". Arney Srackangast, founder of AS1MET Services, said, “AERMOD-HPCS offers the air dispersion modeling community profound improvement over what is currently available from AERMOD, regardless of what hardware you currently possess or are planning to purchase.” Technical reports published on the QA reports pages at this site provide some insights as to why AERMOD-HPCS is faster than the EPA release. The results of workload through-put with concurrent executions reported there (HPC-2007-3) show superior performance results with AERMOD-HPCS when compared to the U.S. EPA version. The latest report (HPC-2007-4) addresses the question "Why is AERMOD-HPCS faster than the EPA distribution?" These reports will be updated regularly to bring information on Windows and Linux platform performance, and quality assurance issues. Since none of the performance enhancement work so far performed by HiCLAS1 has been sponsored by any government agency, the cost-recovery model is to charge a license fee for AERMOD-HPCS and offer an optional Support Service Renewal (SSR) subscription as described on the sales page at this site. Organizations (or individuals) interested in purchasing the AERMOD-HPCS product may also send Email directly to sales@hiclas1.com. Obtaining the product is a simple two-step process
The AERMOD-HPCS product uses the Reprise License Manager (http://www.reprisesoftware.com) and three basic license types are available:
Both the node-locked, and network licenses, come with a "quantity" option where the "quantity" is the count of the required number of concurrent users. Thus, for a single user this is a count of one, whereas for a cluster farm count is as large a number as the customer requires. All licenses, other than the evaluation license are perpetual, however, updates are only available to those with an active SSR subscription. AS1MET Services and HiPERiSM Consulting, LLC, look forward to developing their relationship with the AERMOD user community and welcome their feed-back and suggestions on our products and services. About HiPERiSM Consulting, LLC. HiPERiSM Consulting is privately held and registered with the Secretary of State as a North Carolina Limited Liability Company since 1998, and is a member of the Better Business Bureau of Eastern NC. HiPERiSM specializes in technology transfer to enhance programmer skill levels in OpenMP, MPI and hybrid OpenMP+MPI parallel programming. Specialized courses have sensitized stake-holders in legacy codes to the need for code and performance portability across current and future computer architectures. Current interests include hardware performance metrics, parallel software development, evaluation of compiler performance, portability across parallel computer architectures, and hybrid programming models that match trends in clustered parallel computing. Recent technical studies have utilized proprietary interfaces to hardware performance counters to understand the performance limiting bottle-necks of Air Quality (and other) models. Customers include Universities, Government Agencies, and Corporations across the USA. Further information is available at http://www.hiperism.com, or from George Delic, Ph.D. at george@hiperism.com. About AS1MET Services AS1MET Services is an independent consultancy, founded by Arney Srackangast, specializing in atmospheric dispersion modeling and air pollution meteorology. Mr. Srackangast is recognized as an expert in the development, application, and use of atmospheric dispersion models, as well as related air quality topics, including ambient monitoring, emission inventory development, meteorological data processing, and air quality impact evaluations. Mr. Srackangast has over 20 years experience in managing, performing, and peer reviewing atmospheric modeling studies in support of federal and State air quality evaluations. Mr. Srackangast routinely interacts with both State and federal regulatory agencies to develop thorough modeling methodologies which yield representative results. He also implements regulatory and other (as needed) changes to the Fortran computer code of the models, with both MicroSoft Windows® on personal computers and Linux®/Unix workstations. Mr. Srackangast also has considerable expertise in applying complex computing techniques to analyze large databases to solve a variety of air quality issues. These techniques have benefited from a long-standing expertise in computer languages, data base software, and a broad experience of computers using multiple operating systems.
