Bug in register_host_memory
by Tomasz Rybak
Hello.
I've been packaging PyCUDA for Debian.
I run all the tests to ensure that package works on Python 2
and Python 3. All tests pass except for on from test_driver.py:

I am running PyCuda on a debian6 computer with a GeForce Titan. Driver is 319.32 and Cuda 4.2.
My only problem is when I try to use scikit.cuda (for CuFFT) where sm_35 is not recognized.
The issue is probably located around the old version of cuda.
If you stick to pure PyCuda, it runs fine.

Hi Isaac,
It does not need one, it's a pure Python module. Just run "pip install reikna".

There's no windows 64bit installer.

Hi Isaac,
You can try my package Reikna (http://reikna.publicfields.net). The
FFT there is somewhat slower than the CUFFT one, but it works with
Python 3.

Re: [PyCUDA] FFT

scikits.cuda has both high-level and low-level wrappers from PyCUDA to
CUFFT for all your FFT needs: use the former to do standard tasks
conveniently, and the latter to make full use of the CUFFT API.
