GPU memory management


When using a CPU, one has to deal with a number of memory hierarchies, in the form of the main memory (slowest), to CPU caches (faster), and CPU registers (fastest). A GPU is much the same, in that, one has to deal with a memory hierarchy that can significantly impact the speed of one's applications.

Fastest on a GPU is also the register (or private) memory, of which we have quite a bit more than on the average CPU. After this, we get local memory, which is a memory shared by a number of processing elements. Slowest on the GPU itself is the memory data cache, also called texture memory. This is a memory on the card that is usually referred to as Video RAM (VRAM) and uses a high-bandwidth, but a relatively high-latency memory such as GDDR5.

The absolute slowest is using the host system's memory (system RAM), as this has to travel across the PCIe bus and through various other subsystems in order to transfer any data. Relative to on-device memory systems, host-device communication...
