GPU offload

Support
1

Hello,

I’m investigating using OpenMP GPU offload to run vtkCellTreeLocator->FindCellsWithinBounds on GPU. Is it possible to map it via OpenMP ? If not, is there any solution to do it as parallel execution on GPUs ?

Thanks,
Danial

Hello,

Benefits from GPU processing come from certain types of computations such as matrix/kernel-oriented ones (e.g.: tensor processing in machine learning), mass vectorized operations that can be implemented as texture operations via shaders, etc… I don’t think, if doable, spatial searches can perform better in the GPU, considering transporting the data back and forth CPU memory <–> GPU memory is major bottleneck that will likely offset or even worse any performance gain for that case.

Paulo
