Describe the bug When I run a Taichi kernel with Nvidia CUDA, it always works well. However, when I try it with AMD Vulkan, it will fail.
To Reproduce Here is a sample code.
import time import numpy as np import taichi as ti ti.init(arch=ti.gpu) @ti.kernel # Test kernel def test_kernel(a: ti.types.ndarray(ndim=3), b: ti.types.ndarray(ndim=3)): nslices, nrow, ncols = a.shape for sli, row, col in b: for n in range(nslices): b[sli, row, col] += a[n, row, col] b[sli, row, col] /= nslices m = 64 # Test data size m = 512 a = np.random.random((m, m, m)).astype('float32') b = np.zeros_like(a) t1 = time.time() test_kernel(a, b) t2 = time.time() print(f'Time: {t2-t1}s')

m = 64
