Introduction to Numba: CUDA Programming

numba.cuda.grid(ndim) – Return the absolute position of the current thread in the entire grid of blocks. ndim should correspond to the number of dimensions declared when instantiating the kernel. If ndim is 1, a single integer is returned. If ndim is 2 or 3, a tuple of

Numba support for cuda cooperative block …

問題Numba Cuda has syncthreads() to sync all thread within a block. How can I sync all blocks in a grid without exiting the current kernel? In C-Cuda there’s a cooperativeBlocks library to handle this case. I can’t find something like that in the Numba Docs. Why

Numba provides the cuda.grid(ndim) function to obtain directly the 1D, 2D, or 3D index of the thread within the grid. Alternatively, one can use the following code snippet to control the exact position of the current thread within the block and the grid (code given in

Introduction
Finally, the special object numba.cuda.grid returns the absolute position of the current thread in the entire grid of blocks. Here is an example to concretize the concepts. Here is a kernel that takes an array and increments each value by 1.

Python GPU computing through Numba
Numba supports CUDA-enabled GPU with compute capability (CC) 2.0 or above with an up-to-data Nvidia driver.However, it is wise to use GPU with compute capability 3.0 or above as this allows for double precision operations. Anything lower than a 3.0 CC will only support single precision. will only support single precision.
