taichi - v0.9.0

Published by ailzhang over 2 years ago

Highlights

New features

1. Dynamic indexing of matrices (experimental)

In previous versions of Taichi, a matrix can be accessed only with a constant index. As a result, you cannot perform operations such as clamp the minimum element in a vector to 0:

@ti.kernel
def clamp():
    ...  # assume we have a n-d vector A
    min_index = 0
    for i in range(n):
        if A[i] < A[min_index]:
            min_index = i
    A[min_index] = 0

Of course, you may use the following workaround leveraging loop unrolling. It is, however, neither intuitive nor efficient:

@ti.kernel
def clamp():
    ...  # assume we have a n-d vector A
    min_index = 0
    for i in ti.static(range(n)):
        if A[i] < A[min_index]:
            min_index = i
    for i in ti.static(range(n)):
        if i == min_index:
            A[i] = 0

With this new experimental feature of dynamic indexing of matrices, you can now run the former code snippet smoothly. The feature can be enabled by setting ti.init(dynamic_index=True).

In v0.9.0, a new implicit FEM (Finite Element Method) example (https://github.com/taichi-dev/taichi/blob/master/python/taichi/examples/simulation/implicit_fem.py) is added, which also illustrates the benefit of having this feature. In this example, a huge (12 × 12) Hessian matrix is constructed for implicit time integration. Without dynamic indexing, the whole matrix construction loop needs to be unrolled, which takes 70 seconds to compile; with dynamic indexing, a traditional loop version can be applied, and the compilation time is shortened to 2.5 seconds.

2. Vulkan backend on macOS

Adds support for the ti.vulkan backend on macOS 10.15+ and now you can run GGUI on your macBook. Run the following GGUI examples to try for yourself.

# prerequisites: taichi >= v0.9.0 and macOS >= 10.15
# run GGUI examples
ti example fractal3d_ggui 
ti example fem128_ggui

3. Compatibility with Google Colab

The system would crash if you run Taichi of an earlier version in the Google Colab notebook environment (see #235 for more information). In this release, we refactored our compiler implementation so that Taichi is compatible with Google Colab.

Feel free to run !pip install taichi to install Taichi and start your Colab journey with it.

Improvements

1. More stabilized, better-organized APIs

Ensuring the developers use the right set of APIs is critical to the long-term stability of Taichi's APIs. In this release, we started to reorganize its package structure and deprecate some obsolete or internal APIs. The following table lists some critical APIs that may concern you.

Category	Deprecated API	Replaced with
Builtin	`max()`	`ti.max()`
Builtin	`min()`	`ti.min()`
Atomic operation	`obj.atomic_add()`	`ti.atomic_add()`
Image-specific	`ti.imread()`	`ti.tools.imread()`
Image-specific	`ti.imwrite()`	`ti.tools.imwrite()`
Image-specific	`ti.imshow()`	`ti.tools.imshow()`
Profiler-specific	`ti.print_profile_info()`	`ti.profiler.print_scoped_profiler_info()`
Profiler-specific	`ti.print_kernel_profile_info()`	`ti.profiler.print_kernel_profiler_info()`

For a representative list of APIs deprecated in this release, see this Google doc.

2. Better error reporting

Lengthy traceback in an error report, for most of the time, can be distracting, making it hard to locate the code causing the error. In this release, we've removed the trivial traceback that does not concern developers in our error reporting to improve the debugging experience.

Taking the following code snippet as an example:

import taichi as ti

ti.init()

@ti.func
def bar(a):
    a = a + 2j

@ti.kernel
def foo():
    bar(1)

foo()

Before v0.9.0, the error message looks like this:

[Taichi] Starting on arch=x64

In v0.9.0, the error message looks like this:

  File "/path_to_test/error.py", line 13, in <module>
    foo()
  File "/path_to_taichi/lang/kernel_impl.py", line 732, in wrapped

3. Revamped Taichi's documentation site

To improve the readability and user-friendliness of our documentation, we restructured Taichi's documentation site and incorporated API reference into it.

Join our discussions to build the next Taichi release for you!

We believe that our community plays a pivotal role in the development of the Taichi programming language. In that spirit, we encourage you to take an active part in our GitHub Discussions, propose potential changes, and contribute your ideas. Together, we improve the Taichi language release by release, for you and for every developer.

The following is a selected list of hot topics for you to start with:

#4086
#4183

Specifically, because beginners to Taichi sometimes get lost in different APIs such as ti.Vector, ti.types.vector, ti.Vector.field, we plan to make them clearer and would like to have your opinions on these proposed practices:

Always keep type identifiers in lowercase.
Always use ti.types.vector to define a vector type.
After having type definitions like my_vec2i = ti.types.vector(2, ti.i32), use my_vec2i([5, 10]) for a vector object.
For simplicity, we preserve ti.vector([1, 2]) as a shortcut for ti.types.vector()([1, 2]) , which automatically infers missing type information of the object.
Use ti.field(dtype=my_vec2i, shape=100) for a field object.

taichi - [DO NOT USE] v0.8.6

Published by Leonz5288 almost 3 years ago

Notes:

We added a function to periodically check version information on ti.init to remind users if a new version has been released. However, this function is not fully tested when 0.8.6 is released, and the error handling is not well-implemented. Taichi crashes when it fails to check the version (maybe due to network issues). For this reason, 0.8.6 is removed from the official releases in PyPI. Please upgrade to a newer version if you are on this version. We are sorry for the inconvenience.

taichi - v0.8.0

Published by qiao-bo about 3 years ago

Highlights in v0.8.0

Packed Mode

Previously in Taichi, all non-power-of-two dimensions of a field were automatically padded to a power of two. For instance, a field of shape (18, 65) would have internal shape (32, 128). Although the padding had many benefits such as allowing fast and convenient bitwise operations for coordinate handling, it would consume potentially much more memory than people thought.

For people indeed want smaller memory usage, we now introduce an optional packed mode. In packed mode, no more padding will be applied so a field will not have a larger internal shape when some of its dimensions are not power-of-two. The downside is that the runtime performance will regress slightly.

A switch named packed for ti.init() decides whether to use packed mode:

ti.init()  # default: packed=False
a = ti.field(ti.i32, shape=(18, 65))  # padded to (32, 128)

ti.init(packed=True)
a = ti.field(ti.i32, shape=(18, 65))  # no padding

GGUI

A new GUI system, which is codenamed GGUI, is added to Taichi. GGUI will use GPUs for rendering, which enables it to be much faster than the original ti.gui, and to render 3d meshes and particles. It also comes with a brand new set of immediate mode widgets APIs.

Sample 3D code:

window = ti.ui.Window("Hello Taichi", (1920, 1080))

canvas = window.get_canvas()
scene = ti.ui.Scene()
camera = ti.ui.make_camera()

while window.running:

    camera.position(...)
    camera.lookat(...)
    scene.set_camera(camera)

    scene.point_light(pos=(...), color=(...))

    # vertices, centers, etc. are taichi fields
    scene.mesh(vertices, ...)
    scene.particles(centers, radius, ...)

    canvas.scene(scene)
    window.show()

Sample IMGUI code:

window = ti.ui.Window("Hello Taichi", (500, 500))
canvas = window.get_canvas()

gx, gy, gz = (0, -9.8, 0)

while window.running:

    window.GUI.begin("Greetings", 0.1, 0.1, 0.8, 0.15)
    window.GUI.text("Welcome to TaichiCon !")
    if window.GUI.button("Bye"):
        window.running = False
    window.GUI.end()

    window.GUI.begin("Gravity", 0.1, 0.3, 0.8, 0.3)
    gx = window.GUI.slider_float("x", gx, -10, 10)
    gy = window.GUI.slider_float("y", gy, -10, 10)
    gz = window.GUI.slider_float("z", gz, -10, 10)
    window.GUI.end()

    canvas.set_background_color(color)
    window.show()

For more examples, please checkout examples/ggui_examples in the taichi repo.

Dynamic SNode Allocation

Previously in Taichi, we cannot allocate new fields after the kernel's execution. Now we can use a new class FieldsBuilder to support dynamic allocation.

FieldsBuilder has the same data structure declaration API as the previous root, such as dense(), pointer() etc. After declaration, we need to call the finalize() function to compile the FieldsBuilder to an SNodeTree object.

Example usage for FieldsBuilder:

import taichi as ti
ti.init()

@ti.kernel
def func(v: ti.template()):
    for I in ti.grouped(v):
        v[I] += 1

fb = ti.FieldsBuilder()
x = ti.field(dtype = ti.f32)
fb.dense(ti.ij, (5, 5)).place(x)
fb_snode_tree = fb.finalize() # Finalizing the FieldsBuilder and returns a SNodeTree
func(x)

fb2 = ti.FieldsBuilder()
y = ti.field(dtype = ti.f32)
fb2.dense(ti.i, 5).place(y)
fb2_snode_tree = fb2.finalize() # Finalizing the FieldsBuilder and returns a SNodeTree
func(y)

Additionally, root now is implemented by FieldsBuilder implicitly, so we can allocate the fields directly under root.

import taichi as ti
ti.init() # ti.root = ti.FieldsBuilder()

@ti.kernel
def func(v: ti.template()):
    for I in ti.grouped(v):
        v[I] += 1

x = ti.field(dtype = ti.f32)
ti.root.dense(ti.ij, (5, 5)).place(x)
func(x) # automatically called ti.root.finalize()
# ti.root = new ti.FieldsBuilder()

y = ti.field(dtype = ti.f32)
ti.root.dense(ti.i, 5).place(y)
func(y) # automatically called ti.root.finalize()

Furthermore, after we called the finalize() of a FieldsBuilder, it will return a finalized SNodeTree object. If we do not want to use the fields under this SNodeTree, we could call destroy() manually to recycle the memory into the memory pool.

e.g.:

import taichi as ti
ti.init()

@ti.kernel
def func(v: ti.template()):
    for I in ti.grouped(v):
        v[I] += 1

fb = ti.FieldsBuilder()
x = ti.field(dtype = ti.f32)
fb.dense(ti.ij, (5, 5)).place(x)
fb_snode_tree = fb.finalize() # Finalizing the FieldsBuilder and returns a SNodeTree
func(x)

fb_snode_tree.destroy()
# func(x) cannot be used anymore
