The execution time was 2.75 seconds. For those who are also interested in compile time, the results were: compile 15 seconds assemble 11 seconds link 44 seconds These times were obtained using my normal operating procedure, which involves running with a RAM disk containing a small copy of the system, Fast Finder (TM), Exec, C, Assembler, and Linker. The source files, libraries etc. are on one floppy and EDIT, RMaker, etc. are on the other floppy. I used an Exec job file to compile and link. Timing was started when I pressed the execute button in Exec. Thus the times above include application startup and so on. The complete elapsed time from starting the compile to having an executable version of the program was 70 seconds. While I was at it I decided I might as well make other people jealous by running the test on the UTS system I use at work (running under VM on an Amdahl 470/V8). The results were: execute UTS % timex -p a.out Factoring... A factor of 1394761 is 1181 It took 871 iterations real 0.20 user 0.03 sys 0.01 compile UTS % timex -p cc factor.c real 2.63 user 0.33 sys 0.36 The results reported before were: Compiler Computer Execution time (min:sec.)
