EMPIRE would also appreciate a Kokkos routine to go from a comparator function and some input to a sorted permutation array. It might even be able to provide the relevant...
Notes from EMPIRE's code - Good news: there's a CUDA compatible implementation of quicksort that's been in production use Bad news: it's meant for sorting modest numbers of objects already...
@hamidrezanorouzi For my reference as I'm now starting work on Kokkos sorting enhancements in this vein, what are the elements of your pairs? Are they each themselves integers?
We're discussing adding a comparison based sort. The reason I asked is because I want to prioritize that against generalizing our implementations of integer sorting algorithms (e.g. RadixSort) that outperform...
That was the general plan I had in mind.
This is exactly what EMPIRE does for an SoA of particles, since the permutation needs to be applied to every attribute array.
Does the same configuration pass with GCC 9.x? That might be a good excuse to require a less ancient version
> Does the same configuration pass with GCC 9.x? That might be a good excuse to require a less ancient version If so, this potentially informs #5285
As I understand it, the CUDA flag is there for backwards compatibility, since Kokkos used to allocate UVM by default, and then moved away from that because the most performance...
