mpi4py-fft is a Python package for computing Fast Fourier Transforms (FFTs).
As discussed in #14, GPU support can be achieved relatively easily by swapping `numpy` for `cupy` in a bunch of places. However, the communication is a bit tricky because even...
Hi, I'm aiming to install mpi4py-fft using pip. However, I ended up with the following error ``` error: subprocess-exited-with-error × python setup.py bdist_wheel did not run successfully. │ exit code:...

@dalcinl I had a tiny bit of time over the holidays to pick up this old task that has been on my mind for a couple of years. I noticed...
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](https://github.com/mpi4py/mpi4py-fft/files/13268081/darray.txt) I've tried to run the example code on a...
Hi, I am following the example as in this thread just to make sure that everything works fine, from mpi4py import MPI from mpi4py_fft import PFFT, newDistArray FFT = PFFT(MPI.COMM_WORLD,...
Hi, I find that mpi4py-fft is an excellent tool for performing the FFT in parallel, which greatly improves computational efficiency. However, I don't see anything in the documentation about how...
I guess the source url should be updated from https://bitbucket.org/mpi4py/mpi4py-fft to https://github.com/mpi4py/mpi4py-fft in setup.py and in docs.
This probably doesn't happen often in practice, but using 3 processors for the below code triggers an assertion error in `pencil.py` ([link to line](https://github.com/mpi4py/mpi4py-fft/blob/ac1a26d609cf9553c7a21304bd3729090cd79c0c/mpi4py_fft/pencil.py#L298)). 2 processors causes no problems. ```...
