Subset of cudaDeviceProp fields most users care about. The full C struct is ~1 KB with fields that are rarely accessed — we surface the hot-path ones and keep a reserved _raw slot for the whole buffer so advanced users can cast through.

Fields

name: String

ASCII device name as reported by cudaGetDeviceProperties.

total_global_memory_bytes: u64

Total global memory, in bytes.

shared_memory_per_block_bytes: u64

Maximum shared memory available per block, in bytes.

regs_per_block: i32

Number of 32-bit registers available per block.

warp_size: i32

Warp size in threads (32 on all current architectures).

max_threads_per_block: i32

Maximum number of threads per block.

max_block_dim: [i32; 3]

Maximum block dimensions [x, y, z].

max_grid_dim: [i32; 3]

Maximum grid dimensions [x, y, z].

clock_rate_khz: i32

Peak SM clock frequency, in kHz.

memory_clock_rate_khz: i32

Peak memory clock frequency, in kHz.

memory_bus_width_bits: i32

Width of the global-memory bus, in bits.

l2_cache_size_bytes: i32

L2 cache capacity, in bytes.

max_threads_per_sm: i32

Maximum number of resident threads per SM.

multiprocessor_count: i32

Number of streaming multiprocessors on the device.

compute_capability_major: i32

Major part of the compute capability (e.g. 8 for sm_89).

compute_capability_minor: i32

Minor part of the compute capability (e.g. 9 for sm_89).

integrated: bool

true if the device shares memory with the host (iGPU).

concurrent_kernels: bool

true if the device supports concurrent kernel execution.

pci_bus_id: i32

PCI bus ID.

pci_device_id: i32

PCI device ID.

pci_domain_id: i32

PCI domain ID.
