template<AllocArch Arch, typename LockingPolicy = Spinlock>
class ripple::SimpleAllocator

Defines a simple allocator for either the cpu or the gpu.

Template Parameters

• Arch: The architecture to allocate for.

• LockingPolicy: The locking policy for the allocator.

Public Functions

template<AllocArch ArchType = Arch, std::enable_if_t<ArchType == AllocArch::cpu, int> = 0>
SimpleAllocator() noexcept

Constructor to set the device id for the allocator.

Parameters

• dev_id: The id of the device to allocate for.

template<AllocArch ArchType = Arch, std::enable_if_t<ArchType == AllocArch::gpu, int> = 0>
SimpleAllocator(size_t dev_id) noexcept

Constructor to set the device id for the allocator.

Parameters

• dev_id: The id of the device to allocate for.

auto reserve(size_t bytes) -> void

Reserves The given number of bytes for the allocator.

Parameters

• bytes: The number of bytes to reserve.

auto alloc(size_t size, size_t alignment) -> void*
