* Possible speedup for requesting sie file #1555 When creating the sie file there is a marker string that Trick searches for where it writes the run time allocated memory. The loop that was searching for the string was iterating one character at a time and reading from file each time. This was slow. Changed the loop to read 1Mb into memory at a time and search for the string. Handled the case where the marker string could straddle the 1Mb boundary by copying a small portion of the previous part of the file for the next search. For my one test point sie file generation dropped from 90+ seconds to 3.5 seconds. * Possible speedup for requesting sie file #1555 Math was wrong on some offset values. Fixed them now. * Possible speedup for requesting sie file #1555 The mac won't allow me to declare a "char buff[1000001];". It compiles but throws an exception when run. Changed it to "char *buff = new char[1000001];" |

The Trick Simulation Environment, developed at the NASA Johnson Space Center, is a powerful simulation development framework that enables users to build applications for all phases of space vehicle development. Trick expedites the creation of simulations for early vehicle design, performance evaluation, flight software development, flight vehicle dynamic load analysis, and virtual/hardware in the loop training. Trick's purpose is to provide a common set of simulation capabilities that allow users to concentrate on their domain specific models, rather than simulation-specific functions like job ordering, input file processing, or data recording.
