FOR IMMEDIATE RELEASE
HiCLAS1 Announces AERMOD-HPCS Linux™ ReleaseDurham, North Carolina, 15th April, 2009 HiPERiSM Consulting, LLC, (Durham, North Carolina) and AS1MET Services (Blanco, Texas), operating together as the HiCLAS1 joint venture, announced today the availability of the Linux™ release of AERMOD-HPCS, a High Performance Computing (HPC), single threaded, version of the American Meteorological Society / U.S. EPA Regulatory Model, AERMOD. Also announced is the second release for the 32-bit Microsoft Windows™ operating system where two releases are now available: v1.8.1 (previous) and v1.8.2 (current). For both 32-bit and 64-bit operating systems AERMOD-HPCS v1.8.2 is the first Linux™ release. 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. To coincide with this release four extensive quality assurance reports detail workload throughput (HPC-2009-1, HPC-2009-3) and numerical precision results (HPC-2009-2, HPC-2009-4) across a range Windows™ and Linux™ platforms using processors from the two major chip manufacturers. Platforms tested ranged from laptops to clusters with single, dual, and quad core processors from Advanced Micro Devices® (AMD) and Intel® running both 32-bit and 64-bit operating systems. Performance results showed AERMOD-HPCS is 1.6 to 3.3 times faster than the U.S. EPA's executable model AERMOD.EXE on Windows™ and even faster still on 64-bit Linux™ where the U.S. EPA does not offer a release. In response to repeated requests from AERMOD users, the new QA reports include a cost benefit analysis on the suitability of respective platforms for AERMOD applications. Results with new multi core processors demonstrate surprising numerical results suggesting that while new versions of compilers do offer portable performance, this seems to come at the expense of portable (numerical) precision. Nevertheless AERMOD-HPCS in the new release meets the requirements of a Model Equivalence Demonstration. George Delic, Ph.D., CEO of HiPERiSM Consulting, LLC, said that “with this release of v1.8.2 we have taken the next step up the performance curve for AERMOD in the serial version by porting AERMOD-HPCS to quad core processors which deliver improvements in memory architecture compared to single core processors of just a few years ago. This simple step gives a 2x speed-up on Windows™ platforms and more on 64-bit Linux™. However, it is clear that some new compiler releases are not yet mature enough and they present some portability limitations. The next series of HiCLAS1 reports will focus on these issues". Arney Srackangast, founder of AS1MET Services, said, “we are now working on enabling parallel processing based on this release of AERMOD-HPCS. This development should provide AERMOD users simple linear scaling on multi core platforms at the desk-side without the hassles of additional software layers such as the Message Passing Interface (MPI).” 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.
