What machine did you conduct die TREC experimen[OCRerr] on? SPARC-2GS How much RAM did iL have? 48 MB What was the clock rate of the CPU? 40 MHz V. Some systems are research prototypes and others are commercial. To help compare these Systems: 1. How much "software engineering" went into the development of your system? TIME WAS SPENT TO TRUNCATh RECORD SIZES TO SAVE SPACE AND FIT CERTAIN STRUCTURES IN MEMORY; REPLACE SOME LINKED LISTS WITH ARRAYS. 2. Given appropriate resources, could your system be made to run faster? By how much (estimate)? YES, 50-100%. LOTS OF CODE WAS TRANSLAThD FROM PASCAL TO C & USED AS IS. 3. What features is your system missing that it would benefit by if it had them? DEDICAThD SPARCSTATION WITH MORE RAM, DISK SPACE. 172
