Gcellized FFTW has broken gcell block

GNU Radio
1

Last day’s I installed gcellized FFTW or better I have to say FFTW-WIP,
because the gcellized FFTW svn folder on cgran was empty.
So I downloaded the code using

$ svn co
https://www.cgran.org/cgran/projects/fftw-gcell/branches/developers/eb/fftw-wip

and compiled the source.

$ ./bootstrap.sh

“PLEASE IGNORE WARNINGS AND ERRORS” says bootstrap.sh

abort with error:

(cd .; *.mli *.ml > .depend)
/bin/sh: algsimp.mli: command not found.
make: *** [depend] Error 127

so i’ve done

$ ./configure
$ make
$ make check

make check said: FFTW transforms passed basic tests!

So i installed the FFTW and got binaries in /usr/local/bin (fftw-wisdom)
and
libraries in /usr/local/lib.

After installing FFTW-WIP i looked for a solution to set up with gcell.
But
entering python to do import gcell python said no module named gcell.
Prior it worked. I can import gnuradio and from gnuradio import gcell.
But
import gcell doesn’t work.

I think it could be an issue with gcellized FFTW Code, but at the moment
i
have no answer for this.

Did i everything wrong?

Best regards

First off, consider a few things:

(1) Your subject asserts that code written by somebody else has
caused a problem. That’s not a very friendly way to ask for free
help.

(2) The Cell processor is dead, dead, dead.

(3) There is somewhere between 1 and 3 people on this list who might
be able to assist you if they felt like it. They’re busy people.

(4) You haven’t told us the the first thing about your environment:
no hardware info, no OS info, no mention of which version of the
SDK you’re using…

(5) You haven’t told us what you tried already.

You may want to consider reading this list of suggestions for
increasing your chances of getting help on this list:

OK, i’m sorry for that!

(2) The Cell processor is dead, dead, dead.

Does it mean, no further development in gnuradio code for the Cell
processor?
I appreciate your work and those of others.

I’m using Fedora 11 on PS3, SDK Version 3.1 and GNU Radio 3.2.2.
I need a workload for gcell e.g. i want to use qa_fft.py or gcellized
FFTW.

I apologize for my hasty and rash mailing! I think my subject wasn’t
choosen
very well.

Thanks,

i have already a PS3 with Frimware 3.15 an know about Sony’s OtherOS
removal.
Now i’ve localized the issue: By installing another Package - and it was
not
the gcellized FFTW -
my PYTHONPATH was overwritten. I had to set him new.

Now I set up several Benchmark-Tests like benchmark_nop and
benchmark_dma.
I used qa_fft.py as simple offload, but saw only 2 SPEs working (i used
spu-top to verify).
I think i have to use a bigger FFT e.g. 4K because in qa_fft.py it’s
only
used 32 FFT.

Could you tell me, how to use FFTW-WIP as workload for gcell?
I have a FFTW-WIP binary in /usr/local/bin, which can be execute pretty
well.
But I think, i have to recompile GNU Radio with FLAG to use FFTW-WIP.
Or will FFTW-WIP be used automatically instead of normal FFTW3?

Thanks in advance!

No further development. You can’t buy a new PS3 that will run Linux.
Sony pulled the “OtherOS” feature, and if you happen to allow a
“working” PS3 to update it’s firmware, you’ll lose the feature too and
will no longer be able to run Linux on the one you already have.

I appreciate your work and those of others.

Matty,

I haven’t found time to look at your real problem, but I wanted to
make sure that you knew about Sony’s removal of the OtherOS feature,
and to warn you not to upgrade the firmware on your PS3.
