Taichi

Starting from the v1.2.0 release, Taichi follows [semantic versioning](https://semver.org/) where regular releases cutting from master branch bumps MINOR version and PATCH version is only bumped when cherry-picking critial bug fixes.

Deprecation Notice

Indexing multi-dimensional `ti.ndrange()` with a single loop index will be disallowed in future releases.

Highlights

New features

Offline Cache
We introduced the offline cache on CPU and CUDA backends in [v1.1.0](https://github.com/taichi-dev/taichi/releases/tag/v1.1.0). In this release, we support this feature on other backends, including Vulkan, OpenGL, and Metal.
- If your code behaves abnormally, disable offline cache by setting the environment variable `TI_OFFLINE_CACHE=0` or `offline_cache=False` in the `ti.init()` method call and file an issue with us on [Taichi's GitHub repo](https://github.com/taichi-dev/taichi/issues/new/choose).
- See [Offline cache](https://docs.taichi-lang.org/docs/performance#offline-cache) for more information.

GDAR (Global Data Access Rule)
A checker is provided for detecting potential violations of global data access rules.
1. The checker only works in debug mode. To enable it, set `debug=True` when calling `ti.init()`.
2. Set `validation=True` when using `ti.ad.Tape()` to validate the kernels captured by `ti.ad.Tape()`.
If a violation occurs, the checker pinpoints the line of code breaking the rules.

For example:

import taichi as ti
ti.init(debug=True)

N = 5
x = ti.field(dtype=ti.f32, shape=N, needs_grad=True)
loss = ti.field(dtype=ti.f32, shape=(), needs_grad=True)
b = ti.field(dtype=ti.f32, shape=(), needs_grad=True)

ti.kernel
def func_1():
for i in range(N):
loss[None] += x[i] * b[None]

ti.kernel
def func_2():
b[None] += 100

b[None] = 10
with ti.ad.Tape(loss, validation=True):
func_1()
func_2()

"""
taichi.lang.exception.TaichiAssertionError:
(kernel=func_2_c78_0) Breaks the global data access rule. Snode S10 is overwritten unexpectedly.
File "across_kernel.py", line 16, in func_2:
b[None] += 100
^^^^^^^^^^^^^^
"""


Improvements

Performance
Improved Vulkan performance with loops (6072) (by **Lin Jiang**)

Python Frontend

- PrefixSumExecutor is added to improve the performance of prefix-sum operations. The legacy prefix-sum function allocates auxiliary gpu buffers at every function call, which causes an obvious performance problem. The new PrefixSumExecutor is able to avoid allocating buffers again and again. For arrays with the same length, the PrefixSumExecutor only needs to be initialized once, then it is able to perform any number of times prefix-sum operations without redundant field allocations. The prefix-sum operation is only supported on CUDA backend currently. (6132) (by **Yu Zhang**)

Usage:

N = 100
arr0 = ti.field(dtype, N)
arr1 = ti.field(dtype, N)
arr2 = ti.field(dtype, N)
arr3 = ti.field(dtype, N)
arr4 = ti.field(dtype, N)

initialize arr0, arr1, arr2, arr3, arr4, ...
...

Performing an inclusive in-place's parallel prefix sum,
only one executor is needed for a specified sorting length.
executor = ti.algorithms.PrefixSumExecutor(N)
executor.run(arr0)
executor.run(arr1)
executor.run(arr2)
executor.run(arr3)
executor.run(arr4)


- Runtime integer overflow detection on addition, subtraction, multiplication and shift left operators on Vulkan, CPU and CUDA backends is now available when debug mode is on. To use overflow detection on Vulkan backend, you need to enable printing, and the overflow detection of 64-bit multiplication on Vulkan backend requires NVIDIA driver 510 or higher. (6178) (6279) (by **Lin Jiang**)

For the following program:

import taichi as ti

ti.init(debug=True)

ti.kernel
def add(a: ti.u64, b: ti.u64)->ti.u64:
return a + b

add(2 ** 63, 2 ** 63)
The following warning is printed at runtime:
Addition overflow detected in File "/home/lin/test/overflow.py", line 7, in add:
return a + b
^^^^^


- Printing is now supported on Vulkan backend on Unix/Windows platforms. To enable printing on vulkan backend, follow instructions at https://docs.taichi-lang.org/docs/master/debugging#applicable-backends (6075) (by **Ailing**)

GGUI
- Setting the initial position of GGUI window is now supported. Please refer to this link https://docs.taichi-lang.org/docs/master/ggui#create-a-window to checkout details and usage. (6156) (by **Mocki**)

Taichi Examples
Three new examples from community contributors are also merged in this release. They include:
- Animating the fundamental solution of a Laplacian equation, (6249) (by **bismarckkk**)
- Animating the Kerman vortex street using LBM, (6249) (by **hietwl**)
- Animating the two streams of instability (6249) (by **JiaoLuhuai**)

You can view these examples by running ti example in terminal and select the corresponding index.

Important bug fixes
- "ti.data_oriented" class instance now correctly releases its allocated memory upon garbage collection. (6256) (by **Zhanlue Yang**)
- "ti.fields" can now be correctly indexed using non-i32 typed indices. (6276) (by **Zhanlue Yang**)
- "ti.select" and "ti.ifte" can now be printed correctly in Taichi Kernels. (6297) (by **Zhanlue Yang**)
- Before this release, setting u64 arguments with numbers greater than 2^63 raises error, and u64 return values are treated as i64 in Python (integers greater than 2^63 are returned as negative numbers). This release fixed those two bugs. (6267) (6364) (by **Lin Jiang**)
- Taichi now raises an error when the number of the loop variables does not match the dimension of the ndrange for loop instead of malfunctioning. (6360) (by **Lin Jiang**)
- calling ti.append with vector/matrix now throws more proper error message. (6322) (by **Ailing**)
- Division on unsigned integers now works properly on LLVM backends. (6128) (by **Yi Xu**)
- Operator ">>=" now works properly. (6153) (by **Yi Xu**)
- Numpy int is now allowed for SNode shape setting. (6211) (by **Yi Xu**)
- Dimension check for GlobalPtrStmt is now aware of whether it is a cell access. (6275) (by **Yi Xu**)
- Before this release, Taichi autodiff may fail in cases where the condition of an if statement depends on the index of a outer for-loop. The bug has been fixed in this release. (6207) (by **Mingrui Zhang**)

We are excited to announce the stabilization of the Real Function feature in Taichi Lang v1.7.0. Initially introduced as an experimental feature in v1.0.0, it has now matured with enhanced capabilities and usability.

Key Updates
- Decorator Change: The Real Function now uses `ti.real_func`. The previous decorator, `ti.experimental.real_func`, is deprecated.
- Performance Improvements: Real Functions, unlike Taichi inline functions (`ti.func`), are compiled as separate entities, akin to CUDA's device functions. This separation allows for recursive runtime calls and significantly faster compilation. For instance, the Cornell box example's compilation time is reduced from `2.34s` to `1.01s` on an i9-11900K when switching from inline to real functions.
- Enhanced Functionality: Real Functions support multiple return statements, offering greater flexibility in coding.

Limitations
- Backend Support: Real Functions are currently only compatible with LLVM-based backends, including CPU and CUDA.
- Parallel Loops: Writing parallel loops within Real Functions is not supported. However, if called within a parallel loop in a kernel, the Real Function will be parallelized accordingly.

Important Note on Usage: Ensure all arguments and return values in Real Functions are explicitly type-hinted.

Usage Example
The following example demonstrates the recursive capability of Real Functions. The `sum_func` Real Function is used to calculate the sum of numbers from 1 to n, showcasing its ability to handle multiple return statements and variable recursion depths.


ti.real_func
def sum_func(n: ti.i32) -> ti.i32:
