Detailed Description

Application-implemented class for controlling allocation on the GPU.

Constructor & Destructor Documentation

~IGpuAllocator()

virtual nvinfer1::IGpuAllocator::~IGpuAllocator ( )

inlinevirtual

Destructor declared virtual as general good practice for a class with virtual methods.

TensorRT never calls the destructor for an IGpuAllocator defined by the application.

Member Function Documentation

allocate()

virtual void* nvinfer1::IGpuAllocator::allocate ( uint64_t  size, uint64_t  alignment, uint32_t  flags  )

pure virtual

A callback implemented by the application to handle acquisition of GPU memory.

Parameters

size	The size of the memory required.
alignment	The required alignment of memory. Alignment will zero or a power of 2 not exceeding the alignment guaranteed by cudaMalloc. Thus this allocator can be safely implemented with cudaMalloc/cudaFree. An alignment value of zero indicates any alignment is acceptable.
flags	Reserved for future use. In the current release, 0 will be passed.

If an allocation request of size 0 is made, nullptr should be returned.

If an allocation request cannot be satisfied, nullptr should be returned.

Here is the caller graph for this function:

free()

virtual void nvinfer1::IGpuAllocator::free ( void *  memory )

pure virtual

A callback implemented by the application to handle release of GPU memory.

TensorRT may pass a nullptr to this function if it was previously returned by allocate().

Parameters

memory

The acquired memory.
