info

Implements methods for querying the host target info.

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

from std.sys import CompilationTarget

print(CompilationTarget.is_x86())

Structs

• ​CompilationTarget: A struct that provides information about a target architecture.
• ​Endian: A byte order: the order in which a multi-byte value's bytes are stored.

Functions

• ​align_of: Returns the align of (in bytes) of the type.
• ​bit_width_of: Returns the size of (in bits) of the type.
• ​current_accelerator: Get the current compilation target, which must be an accelerator.
• ​default_accelerator: Get the default accelerator target.
• ​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_amd_rdna_gpu_accelerator: Returns True if the host system has an AMD RDNA 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: Checks whether the current compilation target is an AMD GPU.
• ​is_apple_gpu: Checks whether the current compilation target is an Apple GPU.
• ​is_apple_m5: Returns True if the target is an Apple M5 GPU 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: Checks whether the current compilation target is an NVIDIA GPU.
• ​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.
• ​stdlib_plugin: Returns the stdlib plugin name for the specified target.
