Hi, Are there guidelines on choice of hardware configuration to be made based on image segmentation problem using simple ITK and machine learning algos? Does all ITK filters execute the algorithm routines on GPU by default? Would it help if the segmentation algos are executed on GPU based cloud infra? Thanks, Jiten

Almost all ITK algorithms are executed on CPU. Only the [filters with GPU prefix](https://github.com/InsightSoftwareConsortium/ITK/tree/master/Modules/Filtering) are executed on the GPU. So unless your pipeline uses those GPU\* filters, there will be no benefit of a powerful GPU.

Thanks @dzenanz this would surely help me to decide on hardware I configure for non GPU based seg algos that I use in my worflow. Thanks, Jiten
