Can I use implementation details from hashgrid in another project

[SteffenPL]

Dear NVIDIA-Warp Team,

I'm working on a Julia package for spatial hash tables (SpatialHashTables.jl).

After reading your code in warp/native/hashgrid.h, hashgrid.cpp and hashgrid.cu it is hard to unsee certain tricks.

Is it OK to use these three files as an inspiration for the Julia package? [I am in particular aiming at a decent GPU performance via CUDA.jl.]

I'm asking in particular in order to satisfy the file's license which states:

/** Copyright (c) 2022 NVIDIA CORPORATION.  All rights reserved.

 */

Please let me know if an e-mail is better suited for this question.

Kind regards, Steffen

Hi Steffen, I've been trying to get an answer to your question by contacting our Legal department but haven't found anyone willing to provide an answer. Sorry. I can send you an e-mail of the person who is technically responsible for questions regarding the license Warp uses if you want to follow up with them.

We're now using the Apache 2.0 license so that should make your usage question a lot more straightforward.
