g^i(i\in[1,p-1]) 遍历1 到p-1 ,其中 g 是原根。 如果要进一步学习其原理,建议系统学习相关数论知识。如果只是使用的话,可以记住常用的原根和质数,或者直接网上查表。后文就选取常用的质数 p = 998244353 和原根 g=3 ,为了计算方便,提前算出 g 模p 的逆gi = 332748118 Python代码如下,可以自行比较...

@sirgogo, can you please post the source tofft2D_npandfft2D_tfin your example? Are your ops running on GPU or CPU? (have you verified that withtf.ConfigProto(log_device_placement=True)?) FWIW, NumPy is the oracle used for all ofthe FFT unit tests. The tolerance on those checks is...
(MPI.COMM_WORLD.Get_rank(), u.shape) Running this code with two processors (mpirun -np 2 python pfft_example.py) should raise no exception, and the output should be: 1 (64, 128, 128) 0 (64, 128, 128) This shows that the first index has been shared between the two processors ...
