What is shared memory in CUDA?

Shared memory is a powerful feature for writing well optimized CUDA code. Access to shared memory is much faster than global memory access because it is located on chip. Because shared memory is shared by threads in a thread block, it provides a mechanism for threads to cooperate.

What is the difference between heap and stack?

Stack space is mainly used for storing order of method execution and local variables. Stack always stored blocks in LIFO order whereas heap memory used dynamic allocation for allocating and deallocating memory blocks.

What is constant memory in GPU?

Constant memory is also a read-only cache for global device memory. Constant memory is allocated by host on device. It is not particularly large – for example, it has 64KB on Pascal P100 GPU. Constant memory is fast as long as threads in the same half-warp read the same address, otherwise accesses are serialized.

What is global memory?

The global memory is defined as the region of system memory that is accessible to both the OpenCL™ host and device. There is a handshake between host and device over control of the data stored in this memory. The host processor transfers data from the host memory space into the global memory space.

What is stack memory and heap memory in C#?

Stack is used for static memory allocation and Heap for dynamic memory allocation, both stored in the computer’s RAM . Variables allocated on the stack are stored directly to the memory and access to this memory is very fast, and it’s allocation is dealt with when the program is compiled.

What is stack memory in C?

The stack is a special region of memory, and automatically managed by the CPU – so you don’t have to allocate or deallocate memory. Stack memory is divided into successive frames where each time a function is called, it allocates itself a fresh stack frame.

What is stored in heap C?

The heap is a memory used by programming languages to store global variables. By default, all global variable are stored in heap memory space. It supports Dynamic memory allocation. The heap is not managed automatically for you and is not as tightly managed by the CPU. It is more like a free-floating region of memory.
