1.2.3 Computer Hardware Requirements
184.108.40.206 PC Hardware Requirements.
Given the rapid increase in speed and capacity of personal computers (PCs) available for modeling in recent years, and their relative ease of use and access, the PC has become the most popular environment for performing dispersion modeling applications within the modeling community (Bauman and Dehart, 1988; Rorex, 1990). This trend can be expected to continue in the future. The current versions of the ISC models were developed on an IBM‑compatible PC using the Microsoft FORTRAN Optimizing Compiler (Version 5.1), and have been designed to run on such machines with a minimum of 640K bytes of RAM and MS‑DOS Version 3.2 or higher. In order to handle the input data files (runstream setup and meteorology) and the output files, it is highly recommended that the system have a hard disk drive. The amount of storage space required on the hard disk for a particular application will depend greatly on the output options selected. Some of the optional output files of concentration data can be rather large. More information on output file products is provided in Sections 2 and 3.
While a math coprocessor chip is optional for execution of the ISC models on a PC, it is highly recommended, especially for the Short Term model, due to the large increase in execution speed that will be experienced. The model may be expected to run about five to ten times faster with a math coprocessor than without one.
