CRDSS <br />TASK MEMORANDUM 1.05-14 <br />Study of System Integration Issues <br />General Performance Issues <br />1.0 ISSUE <br />A decision support system (DSS) is designed to provide timely and valuable input to problem- <br />solving. However, because of the complexity of the problems being addressed, DSSs often have <br />performance problems related to the speed of the system. It is important that the performance of the <br />CRDSS be fast enough not to hinder the efforts of users and still provide results that are within <br />acceptable tolerances. This memorandum addresses the following general issues related to system <br />performance: <br />How will the real-time access of the CRDSS database be optimized? <br />? <br />How will the transfer of data from the CRDSS database to flat files for models via DMI <br />? <br />utilities be optimized? <br />In general, how will the performance of code be optimized to give the best processing <br />? <br />results? <br />How will the performance of models be optimized? <br />? <br />How will the interaction of the system and the network be optimized to give the best <br />? <br />performance? <br />How will the system be configured to give the best performance for multiple users? <br />? <br />How will the use of output devices be optimized to give the best performance? <br />? <br />2.0 DISCUSSION/ANALYSIS <br />The general configuration of the system during development will be that a master copy of the system <br />(software, database, documentation) will exist at the RTi office in Fort Collins, and a copy of the <br />current prototype software will exist on the Briefing Room machine in Denver. Dated copies of the <br />system will exist at RTi and CSU as products of the prototyping cycle (see Task Memorandum 1.05- <br />22). <br />The Briefing Room machine hardware was selected to represent a typical workstation that would be <br />used to access the CRDSS in its full capacity (full database access, modeling capabilities, and <br />graphics capabilities). The machine in place at this time is a Silicon Graphics, Inc. (SGI) Indy <br />workstation, which is the least-expensive SGI machine. RTi encouraged the State to use a typical <br />machine for the Briefing Room workstation (as opposed to an expensive, high-powered machine) so <br />that the CRDSS can be tested in an environment that will be indicative of the final user environment. <br />Such an environment will force the development team to address performance issues for each <br />1 <br />A275 05.10.94 1.05-14 Malers, Brazil <br />
