> Right now ArrowBuf can only point to memory managed by an Arrow Allocator.
> This is because in many cases we want to be able to support hierarchical
> accounting of memory and the ability to transfer memory ownership between
> separate allocators within the same hierarchy.
> At the same time, there are definitely times where someone might want to map
> some amount of arbitrary off-heap memory. In these situations they should
> still be able to use ArrowBuf.
> I propose we have a new ArrowBuf constructor that takes an input that
> subclasses an interface similar to:
> {code}
> public abstract class Memory {
> protected final int length;
> protected final long address;
> protected abstract void release();
> }
> {code}
> We then make it so all the memory transfer semantics and accounting behavior
> are noops for this type of memory. The target of this work will be to make
> sure that all the fast paths continue to be efficient but some of the other
> paths like transfer can include a conditional (either directly or through
> alternative implementations of things like ledger).

[jira] [Commented] (ARROW-4716) [Benchmarking] Make maching detection script cross-platform

Tanya Schlusser commented on ARROW-4716:
Linux first is a great choice.
Python is my favorite language and I am happy to do this. The existing shell
script was only because it was easy and quick.
I am very very sorry for dropping the ball the past couple of months. My mom
passed away and I have been a total wreck (and moved back home from her house
and got a job) but I still want to contribute and hope you will accept me back
now. You all rock very much!

> The machine detection script ({{make_machine_json.sh}}) currently looks like
> it will only work properly on macOS. Ideally it should work more or less
> correctly on all of them macOS, Linux and Windows (some values may remain
> undetected on some platforms).
> This probably entails:
> - switching to Python rather than bash
> - using something like [psutil|https://psutil.readthedocs.io/en/latest/] to
> grab useful machine information
> - calling {{nvidia-smi}} to query GPU characteristics (for example
> "nvidia-smi -q -i 0 -x")
