Mojo module

info

Implements methods for querying the host target info.

You can import these APIs from the sys package. For example:

from sys import CompilationTarget

print(CompilationTarget.is_x86())

Structs

CompilationTarget: A struct that provides information about a target architecture.

Functions

align_of: Returns the align of (in bytes) of the type.
bit_width_of: Returns the size of (in bits) of the type.
has_accelerator: Returns True if the host system has an accelerator and False otherwise.
has_amd_gpu_accelerator: Returns True if the host system has an AMD GPU and False otherwise.
has_apple_gpu_accelerator: Returns True if the host system has a Metal GPU and False otherwise.
has_nvidia_gpu_accelerator: Returns True if the host system has an NVIDIA GPU and False otherwise.
is_32bit: Returns True if the maximum integral value is 32 bit.
is_64bit: Returns True if the maximum integral value is 64 bit.
is_amd_gpu: Returns True if the target triple of the compiler is amdgcn-amd-amdhsa False otherwise.
is_apple_gpu: Returns True if the target triple is for Apple GPU (Metal) and False otherwise.
is_big_endian: Returns True if the target's endianness is big and False otherwise.
is_gpu: Returns True if the target triple is GPU and False otherwise.
is_little_endian: Returns True if the target's endianness is little and False otherwise.
is_nvidia_gpu: Returns True if the target triple of the compiler is nvptx64-nvidia-cuda False otherwise.
is_triple: Returns True if the target triple of the compiler matches the input and False otherwise.
num_logical_cores: Returns the number of hardware threads, including hyperthreads across all CPU sockets.
num_performance_cores: Returns the number of physical performance cores across all CPU sockets. If not known, returns the total number of physical cores.
num_physical_cores: Returns the number of physical cores across all CPU sockets.
platform_map: Helper for defining a compile time value depending on the current compilation target, raising a compilation error if trying to access the value on an unsupported target.
simd_bit_width: Returns the vector size (in bits) of the specified target.
simd_byte_width: Returns the vector size (in bytes) of the specified target.
simd_width_of: Returns the vector size of the type on the host system.
size_of: Returns the size of (in bytes) of the type.
