Detailed Description

template<typename T>
requires std::is_trivially_copyable_v<T>
class uni20::cuda::PartitionedCudaBuffer< T >

One CUDA allocation partitioned into independent logical buffers.

Construction validates the disjoint ranges once. Each child owns an independent completion ledger while sharing the physical allocation and device resources with its siblings.

Member Function Documentation

buffer() [1/2]

template<typename T >

CudaBuffer< T > & uni20::cuda::PartitionedCudaBuffer< T >::buffer ( std::size_t  ordinal )

inline

Return one mutable logical child buffer.

buffer() [2/2]

template<typename T >

CudaBuffer< T > const & uni20::cuda::PartitionedCudaBuffer< T >::buffer ( std::size_t  ordinal ) const

inline

Return one read-only logical child buffer.

buffer_count()

template<typename T >

std::size_t uni20::cuda::PartitionedCudaBuffer< T >::buffer_count ( ) const

inlinenoexcept

Return the number of logical child buffers.

device()

template<typename T >

Device uni20::cuda::PartitionedCudaBuffer< T >::device ( ) const

inline

Return the CUDA device containing the physical allocation.

read_synchronized_with()

template<typename T >
requires std::is_trivially_copyable_v<T>

auto uni20::cuda::PartitionedCudaBuffer< T >::read_synchronized_with

(

Stream const &

stream

)

const -> PartitionedReadAccess<T>

Acquire read access to the complete contiguous allocation.

The access waits on every child ledger and publishes one shared completion to all children on release.

resources()

template<typename T >

DeviceResources & uni20::cuda::PartitionedCudaBuffer< T >::resources ( ) const

inline

Return the device resources shared by every child buffer.

size()

template<typename T >

std::size_t uni20::cuda::PartitionedCudaBuffer< T >::size ( ) const

inlinenoexcept

Return the total physical allocation size in elements.

write_synchronized_with()

template<typename T >
requires std::is_trivially_copyable_v<T>

auto uni20::cuda::PartitionedCudaBuffer< T >::write_synchronized_with

(

Stream const &

stream

)

-> PartitionedWriteAccess<T>

Acquire write access to the complete contiguous allocation.

The access waits on every child ledger and publishes one shared completion to all children on release.
