We have code that reads in a DXF/DWG file (drawing file) and then our own geometry library that converts everything into point, line, arcs, circles, and etc. objects. Then we have a Shape object which will hold one or many entities. Shapes can also contain other shapes as children and those shap...
I have a directory with 'sets' of files that start with a state name followed by 4 or 5 digits (typically indicating year). Each 'file set' contains 3 files a .txt, a .png, and a .jpg.

I've created a serial C++ code for gravitational N-Body calculation. Because I expect to have upwards of 8-71 sparse bodies (ie, where Barnes-Hut is not necessarily practical) and running for long periods of time, I want to make as much use of parallelization and vectorization as possible. I did ...
