Example reproduction error

[ALWXAE]

Hello everyone,

I tried out your great package and tested this example (https://github.com/mpi4py/mpi4py-fft/blob/master/examples/darray.py) with minor attachment to print out s0,s1,s2:

darray.txt

I've tried to run the example code on a total of 1-8 nodes with python 3.11.6, but the code runs successfully only in the case of 1, 2, 3 and 5 nodes, otherwise error assertion arises: assertion_error.txt

Attached are output of different processor numbers: nproc1.txt nproc2.txt nproc3.txt nproc4.txt nproc5.txt nproc6.txt nproc7.txt nproc8.txt

As you can see, the output changes for certain processor numbers, but I am unsure why. Help would be appreciated. Regards Hanru

Hi Sorry about the late reply. I cannot seem to reproduce this. I have no errors for 6 nodes or less. For 7 I get an error, but that is because one of the arrays is of size (6, 6, 6).
