Xraytrace documentation

Graphics card use is still in the evaluation phase, so it is reasonable to check every calculation first on CPU (e.g. for a single angle) and then to run the graphics card calculation.

To set the graphics card use on, we can run this command

GPU
1

and by using 0 we would switch it off. If we have multiple graphics cards in the system, we can choose which one will run the calculation, e.g. by using command

UGPU
1

which means that the GPU with index 1 will be used (second GPU in the system, as they are numbered from 0).
