Programming Model¶

`program_id`	Returns the id of the current program instance along the given `axis`.
`num_programs`	Returns the number of program instances launched along the given `axis`.

`arange`	Returns contiguous values within the open interval [`start`, `end`).
`zeros`	Returns a block filled with the scalar value 0 for the given `shape` and `dtype`.

`broadcast_to`	Tries to broadcast the given block to a new `shape`.
`reshape`	Tries to reshape the given block to a new shape.
`ravel`	Returns a contiguous flattened view of `x`

Returns the matrix product of two blocks.

`load`	Return a block of data whose values are, elementwise, loaded from memory at location defined by `pointer`.
`store`	Stores `value` block of elements in memory, element-wise, at the memory locations specified by `pointer`.
`atomic_cas`	Performs an atomic compare-and-swap at the memory location specified by `pointer`.
`atomic_xchg`	Performs an atomic exchange at the memory location specified by `pointer`.

Returns a block of elements from either x or y, depending on condition.

`exp`	Computes the element-wise exponential of `x`
`log`	Computes the element-wise natural logarithm of `x`
`cos`	Computes the element-wise cosine of `x`
`sin`	Computes the element-wise sine of `x`
`sqrt`	Computes the element-wise square root of `x`
`sigmoid`	Computes the element-wise sigmoid of `x`
`softmax`	Computes the element-wise softmax of `x`

`max`	Returns the maximum of all elements in the `input` block along the provided `axis`
`min`	Returns the minimum of all elements in the `input` block along the provided `axis`
`sum`	Returns the sum of all elements in the `input` block along the provided `axis`

`atomic_cas`	Performs an atomic compare-and-swap at the memory location specified by `pointer`.
`atomic_add`	Performs an atomic add at the memory location specified by `pointer`.
`atomic_max`	Performs an atomic max at the memory location specified by `pointer`.
`atomic_min`	Performs an atomic min at the memory location specified by `pointer`.

`minimum`	Computes the element-wise minimum of `x` and `y`.
`maximum`	Computes the element-wise maximum of `x` and `y`.

`randint4x`	Given a `seed` scalar and an `offset` block, returns four blocks of random `int32`.
`randint`	Given a `seed` scalar and an `offset` block, returns a single block of random `int32`.
`rand`	Given a `seed` scalar and an `offset` block, returns a block of random `float32` in \(U(0, 1)\)
`randn`	Given a `seed` scalar and an `offset` block, returns a block of random `float32` in \(\mathcal{N}(0, 1)\)

Let the compiler knows that the values in input are all multiples of value.
