Re: [otb-users] efficient use of hardware resources by OTB

[Guillaume Pasero]

Hi, First thing to know is that during TrainImagesClassifier, some parts of the processing are mono-threaded (only 1 CPU used). This is a design limitation. However, the multi-threaded parts of this application should be able to use all the CPUs available. About the memory consumption, the RAM parameter in the application should set the maximum RAM amount to be used. I think that in the case of TrainImagesClassifier, this setting is difficult to derive because it depends on the polygon density in your training/validation vector layer. If you use an other application that is more like an "image to image" processing, you should see the expected behaviour more clearly.

Is there way to set the number of cores to be used during this processing as well as the amount of RAM.
