Ishan Chattopadhyaya commented on LUCENE-7745:
----------------------------------------------
bq. Your thoughts please...
Thanks for your interest in this. Seems like your proposed ideas are very much
inline with our approach that we're trying out as well. There are some initial
experiments and results that we are performing as we speak, and I can see that
there are benefits in the niche usecases that Adrien mentioned.

> There are parts of Lucene that can potentially be speeded up if computations
> were to be offloaded from CPU to the GPU(s). With commodity GPUs having as
> high as 12GB of high bandwidth RAM, we might be able to leverage GPUs to
> speed parts of Lucene (indexing, search).
> First that comes to mind is spatial filtering, which is traditionally known
> to be a good candidate for GPU based speedup (esp. when complex polygons are
> involved). In the past, Mike McCandless has mentioned that "both initial
> indexing and merging are CPU/IO intensive, but they are very amenable to
> soaking up the hardware's concurrency."
> I'm opening this issue as an exploratory task, suitable for a GSoC project. I
> volunteer to mentor any GSoC student willing to work on this this summer.
