Detailed Description

Generic cached memory manager. This class can be used to speed-up memory allocations and deallocations from arbitrary direct memory managers.

Constructor & Destructor Documentation

◆ MemoryManagerCached()

open3d::core::MemoryManagerCached::MemoryManagerCached ( const std::shared_ptr< MemoryManagerDevice > &  device_mm)

Constructs a cached memory manager instance that wraps the existing direct memory manager device_mm.

Member Function Documentation

◆ Free()

void open3d::core::MemoryManagerCached::Free ( void *  ptr,
const Device device 

Frees previously allocated memory at address ptr on device device.

Implements open3d::core::MemoryManagerDevice.

◆ Malloc()

void * open3d::core::MemoryManagerCached::Malloc ( size_t  byte_size,
const Device device 

Allocates memory of byte_size bytes on device device and returns a pointer to the beginning of the allocated memory block.

Implements open3d::core::MemoryManagerDevice.

◆ Memcpy()

void open3d::core::MemoryManagerCached::Memcpy ( void *  dst_ptr,
const Device dst_device,
const void *  src_ptr,
const Device src_device,
size_t  num_bytes 

Copies num_bytes bytes of memory at address src_ptr on device src_device to address dst_ptr on device dst_device.

Implements open3d::core::MemoryManagerDevice.

◆ ReleaseCache() [1/2]

void open3d::core::MemoryManagerCached::ReleaseCache ( )

Frees all releasable memory blocks on all known devices. Note that this may also affect other instances of MemoryManagerCached.

◆ ReleaseCache() [2/2]

void open3d::core::MemoryManagerCached::ReleaseCache ( const Device device)

Frees all releasable memory blocks on device device.
