Detailed Description

Mutable stream and provider resources associated with one CUDA device.

Ordinary application code obtains the canonical instance from the installed CUDA runtime. Direct construction remains useful for focused tests and low-level bring-up. The resources object must outlive every buffer, stream lease, and provider lease created from it. A dedicated reclamation stream orders allocation release after buffer completion events without consuming an operation-stream slot.

Constructor & Destructor Documentation

DeviceResources() [1/3]

uni20::cuda::DeviceResources::DeviceResources ( Config  config )

explicit

Create isolated resources for one CUDA device.

DeviceResources() [2/3]

uni20::cuda::DeviceResources::DeviceResources ( DeviceResources const &  )

delete

DeviceResources() [3/3]

uni20::cuda::DeviceResources::DeviceResources ( DeviceResources &&  )

delete

~DeviceResources()

uni20::cuda::DeviceResources::~DeviceResources ( )

noexcept

Member Function Documentation

device()

Device uni20::cuda::DeviceResources::device ( ) const

inlinenoexcept

Return the device served by this resource set.

live_allocation_count()

std::size_t uni20::cuda::DeviceResources::live_allocation_count ( ) const

inlinenoexcept

Return the number of live CUDA allocations borrowing these resources.

operator=() [1/2]

DeviceResources & uni20::cuda::DeviceResources::operator= ( DeviceResources &&  )

delete

operator=() [2/2]

DeviceResources & uni20::cuda::DeviceResources::operator= ( DeviceResources const &  )

delete

provider_resource()

template<class Resource , class... Args>

Resource & uni20::cuda::DeviceResources::provider_resource ( Args &&...  args )

inline

Return the resource-owned instance of one provider resource type.

The resource is constructed on first use and retained until shutdown. A device owns at most one instance of each concrete resource type. Provider resources are destroyed before the stream pool that they may reference.

streams() [1/2]

StreamPool const & uni20::cuda::DeviceResources::streams ( ) const

inlinenoexcept

streams() [2/2]

StreamPool & uni20::cuda::DeviceResources::streams ( )

inlinenoexcept

Return the device's actually-idle stream pool.
