parallel computing

[cvavrus]

Hi there,

I am currently trying to run CANUPO via the command line to classify an extremely large point cloud. Currently, this operation has been crashing my computer, so I have been looking into running this process on a super computer available to me that I believe uses multiple cores. I do not know much about parallel computing, but I was wondering if you could help me to understand first of all if running CANUPO using parallel processing is possible and also how I would adjust the code to do so if it is possible. Hopefully this request makes sense.

Thanks very much,
Claire

Normally the CANUPO plugin will automatically use multiple cores if available. Even on a standard PC, if you have multiple cores you should see all of them working (depending on the step of the algorithm, they can't be all parallelized).

And if it is a crash issue, then it's probably more the memory which is the limiting factor?
