Adding `Target` and `InstructionProperties` representations to rust #12292

raynelfss · 2024-04-23T20:34:06Z

Summary

Fixes #12052

~~Currently blocked by #12459~~ thanks @mtreinish!

As we continue moving more parts of the transpiler to Rust, it is important that some of the important data about the devices we're compiling for is easily accessible from the Rust side of things. These commits aim to implement representations of both the Target and InstructionProperties classes, allowing most of their data to live inside of Rust but still be usable in Python.

Details and comments

qiskit._accelerate now has a target module which includes both the BaseTarget and BaseInstructionProperties structs.
Here's a more detailed description of what has changed:

Rust

BaseTarget will include the main data that the Target has in python. This will include all of the publicly available attributes of the existing Target class, except for the following:
- _coupling_graph: of type rustworkx.PyDiGraph
- _instruction_durations: of type InstructionDurations
- _instruction_schedule_map: of type InstructionScheduleMap
Due to these properties are not usable through Rust without using python api's, they were left in python.
- This representation is purely additive through Python and non mutable through Rust.
BaseInstructionProperties represents the main data of `InstructionProperties, that being:
- Error: f64,
- Duratlon: f64

Python:

Target: this is a subclass of BaseTarget and has the missing attributes + functions from the previous version.
- In addition it stores a copy of the _gate_map attribute from the rust side for easy access in python without conversions from rust.
- We ensure that the data from Target._gate_map is identical to the data in super().gate_map by calling the super()'s equivalent function when adding or updating an instruction.
InstructionProperties: is a subclass of BaseInstructionProperties
- The attribute of calibration to store the instruction's calibration object is present in this representation along with it's custom setter and getter.

Possible breaking changes:

- InstructionProperties is now PyO3 class which means it cannot be subclassed by overloading __init__() alone. The new architecture would require users to extend both __new__ and __init__ to add extra properties. These wouldn't necessarily be visible in rust. Fixed!

Broken tests

~~A procedure performed in Aer that attempts to erase the Target's internal data is no longer possible due to the these attributes being hidden from python.~~ Solved by Qiskit/qiskit-aer#2142

Overall I think this is about ready to merge. I think there will definitely be an interative process where we refine this as we start using it more. But this has all the pieces we need to start and only will cost a bit extra memory for a rust space copy of the properties. I left a few inline comments, but the big things I think we must fix before moving forward here are the docstrings for BaseTarget should describe BaseTarget's functionality and what/how it is to be used. Even though it's a private class and only for Qiskit internals having the docstrings read like the python space target is confusing.

The other big one is I think dropping Mapping from the Python space Target is a breaking api change and we should be able to avoid that, I think metaclass=Mapping or something similar will work to fix that and let you inherit from BaseTarget and still register the class as a Mapping.

This is more a comment for a future performance optimization to investigate in a follow up PR (we can convert this to a tracking issue after the PR merges)

All the String entries here are all the same set of strings. Ideally we should have only one owned string copy as the canonical name and the others are all just &str references to that single string. We might have issues with lifetimes on this as a pyclass, but we could do something like have a gate_names: Vec<String> and then replace all the strings by a usize index.

Ok, that makes sense. My comment was more about the method name and the docstring identical to the python one. This is really a different method from the python space add_instruction it's a subset of the functionality for handling the rust data but everything is showing it looks like the python space.

+/// fully implement all the methods present in `IndexMap<K, V>` due to API limitations.
+#[derive(Debug, Clone)]
+pub struct NullableIndexMap<K, V>


With this warning do we want to make this fully public, or can we constrain this to pub(crate)? This is really only used internally for the Target right, so we may return it to python (but that doesn't matter for this) and we can avoid exposing this directly for accessing the target from rust right? (although all the usage right now is potentially coming from the same crate)

Well, with this one it's a little complicated. Even though it is currently being used only in Target, it might be usable for other things in the future where we have to store a nullable value inside of a dict-like structure. And maybe someone could build on top of it.

However, the main reason why I made it public is that if we call Target.values the value that is returned is an instance of NullableIndexMap and, if we wanted to avoid that, we'd have to reconstruct the IndexMap entirely. Of course, there might be a better way to approach this so I'm curious as to which ideas you might have.

qiskit/transpiler/target.py

- Minor corrections from Matthew's review.

- Due to the private nature of `NullableIndexMap`, the `Target` has to be made crate private. - Add temporary`allow(dead_code)` flag for the unused `Target` and `NullableIndexMap` methods. - Fix docstring of `Target` struct. - Fix docstring of `add_instruction`. - Make several python-only operations public so they can be used with other `PyClass` instances as long as they own the gil. - Modify `py_instruction_supported` to accept bound objects. - Use rust-native functions for some of the instance properties. - Rewrite `instruction` to return parameters as slice. - `operation_names` returns an `ExactSizeIterator`. - All rust-native methods that return an `OperationType` object, will return a `NormalOperation` instance which includes the `OperationType` and the parameters.

I think this is ready to go now. I have a few very small nits inline. But for a 2k line change I think I can continue to look at this and find something forever. so after these are fixed I'll approve and we can merge this. I think there are some potential cleanups we'll want to do down the road, but this is a great start and gets us the data model for the target in rust to start leveraging in various places.

This will conflict with @jakelishman's PR #12730 I think because that removes OperationType but it shouldn't be too hard to update this with that or vice versa if this merges first.

+pub(crate) struct NormalOperation {
+    pub operation: OperationType,
+    pub params: SmallVec<[Param; 3]>,
+    op_object: PyObject,


Isn't this largely duplicative with the other fields? Is there something we gain by storing this too? Is it just so you don't have to construct it on the fly again if a user requests the operation object for a name?

Yes, that is exactly the purpose of this. So that we don't have to reconstruct the Operation object. However, I understand that Jake's changes in #12730 might reshape the way this is done. So storing the op_object might not be necessary after that merges, so maybe we should wait for that PR.

Another note for a follow-up we should add rust space tests for these, since they're meant to be consumed from rust we should be able to test them without python.

The only thing I think we should mention here is around where we have copies of data or not and how we keep things in sync. Just so people will understand the split in responsibilities between the python space and the rust space. Otherwise this is much better.

- Mention duplication in docstring for rust Target. - Use f"{*:g}" to avoid printing the floating point for 0 in `Target`'s repr method. - Add note mentioning future unit-tests in rust.

LGTM, thanks for all the hard work on this @raynelfss. I think this is ready to merge. There are some small things I outlined in my earlier reviews that we can fix in follow ups. This is a new rust space representation so just like with everything we're migrating over there will likely be a longish tail of follow-ups we'll make to make incremental improvements as we start to use it more. But this is definitely in a state where I think it's good to start working with.

This all being said I'm going to hold off on pushing the automerge button right now, because I think we should wait until we branch 1.2.0 for this. Since nothing in 1.2.0 will use this I think it's better to just include this in 1.3.0.
