Dec 09, 2010 Hi everyone, I'm having trouble getting a float2 to properly coalesce. I've tried to make a simple example to run in the visual profiler but it always returns noncoalesced reads. The GPU hardware provides load instructions for 32bit, 64bit and 128bit data, which maps to the float, float2, and float4 data types (as well as to the int, int2, and int4 types). The data must be naturally aligned for the load instructions to work correctly and in Functions and operators. This chapter introduces the functions and operators executable on GPU devices.

A complete description of the runtime can be found in the CUDA reference manual. The runtime is built on top of a lowerlevel C API, the CUDA driver API, which is also accessible by the application.
