I am curious if any of you experienced developers has ever thought about
using GPU as a CPU (or Co-CPU) in order to boost calculation speed... ?
Is it or is not possible?

Most of GRASS' performance issues arise from the fact that code
simplicity takes precedence over perfomance.

Writing optimised code requires a fair amount of effort, and
maintaining optimised code is even worse. Consequently, most of GRASS
is written without even basic optimisations, let alone more extreme
measures such as using a GPU as a co-processor.

I can't imagine how much faster could be GRASS! I mean, it's faster than
most other GIS tools... so if "performance programing" would be
mandatory for "core modules" then it would ...flyyyy!!! (?)

Thanks for the detailed information :wink:
