Hi Ron,
Thank you very much!
I am sure I will have questions later on how to use FFT with windows
(Harris Blackman, Kaiser, Hamming, etc.) but that is another story and I
will do a new posting on that when I reach that point.
Thank you very much!
Happy Holiday Season!

You have to copy your samples into get_inbuf() first. That's where FFTW
expects the data. *dst is just a convenience variable to allow for less
typing. Instead of:
memcpy(ofdm_fft.get_inbuf(), in, sizeof(gr_complex) * ofdm_fft_size);
You can use:
memcpy(dst, in, sizeof(gr_complex) *
Hi Ron,
Sorry for bothering some more!
In Debugging it appears that dst is not pointing to the input data (
input_items[0]), which we pointed to with pointer variable in at the start
of the work(...) method
(const gr_complex *in = (const gr_complex *) input_items[0];
Here is a snippet of my
Thanks Ron! I really appreciate your help!

Gwendoline:
I think you may have conflicting versions of GNURadio and/or Fosphor. I have
had this error before as well.
I use fosphor on a daily basis on both GNURadio 3.8 and 3.9 and I can confirm
that it does work on several different nvidia GPU’s as Sylvain said. I have had
some issues

Hi,
I install the package but before testing it I see a new problem.
Gnuradio is in version 3.9.4.0.
The fosphor sink block is in error so I can't run the flowgraph.
No matter what Window type I put, I have this error in block parameters:

Hi all,
Gentle reminder to submit proposals for presentations about e.g. your own
projects, FOSS projects updates or other fun hacks you want to talk about. Our
CfP is still open until (and including) December 26th. Do not hesitate to
contact any of the Devroom managers if you have questions.
Hi,
If you're using Ubuntu, you can try the intel-opencl-icd package which
is the binary package for https://github.com/intel/compute-runtime
which is the OpenCL driver for Intel GPUs.
However, I'm not sure anyone has ever run fosphor with it ... not sure
if it supports the features required, I
Hi Sylvain,
I realize that I'm not sure of how I install the gr-fosphor package. I download
the .deb (gr-fosphor_3.8~2.2d4fe78-1build3_amd64.deb) and I install it. I did
that because I don't really understand what to do by reading the wiki fosphor.
So I'm back in Gnuradio 3.9

Definitely go for 3.9
I only maintain it for the latest version of gnuradio ( so it might be
3.10 only soon ... ).
