A method and apparatus of a network device that allocates a shared memory buffer for an object is described. In an exemplary embodiment, the network device receives an allocation request for the shared memory buffer for the object. In addition, the network device allocates the shared memory ...
With HMM, we can use allocator like malloc to manage host and device memory. Does this mean that there is no need to use SVM and HSA with HMM, or HMM is the basis of SVM and HAS to implement Fine-Grained system SVM defined in the opencl spec? 有人可以解释一下SVM(英特尔共享虚拟内存...

Allocator 分配器的类型。 alloc 要复制的分配器。 备注 这些运算符均会递减 *this 当前拥有资源的引用计数,并将操作数序列命名的资源所有权分配给 *this。 如果引用计数降至零,则释放资源。 如果运算符操作失败,则保持 *this 不变。 示例 C++ 复制 // std__memory__shared_ptr_reset.cpp // compile with...
