Vista, Xp, or Linux?

GNU Radio
1

Hello all,

I just got my new notebook computer with Vista pre-installed. I have
a
couple questions.

  1. Has anyone had any luck installing GNURadio under Vista using Cygwin
    or
    MinGW method?

  2. Are there any performance issues running GNURadio under windows (XP
    or
    Vista) as opposed to Linux?

Thanks!

You will be much happier if you run linux. XP usually works ok, but
unless you have a real pressing need to not run Linux, that is what I
would suggest. I don’t know if anyone has tried Vista.

Hi Kevin,

I haven’t tried Vista. I don’t expect it to be different from XP, but
we
won’t know until someone tries it.

    Vista) as opposed to Linux?

It is certainly easier to install GNU Radio on Linux, but it does work
under
both Cygwin and MinGW as well.

I mostly run the MinGW version but have also built and tested it under
Cygwin and Debian Linux. For my application the MinGW version is the
fastest (50-60% of cpu time), the Cygwin version is the slowest (70-80%
of
cpu), and the Linux version is somewhere in between. I haven’t tracked
down
what causes the difference; it could be something as simple (and
fixable) as
compile options for FFTW or as complicated (and difficult to fix) as
graphics display speed.

One advantage of Windows is that you can set the priority of the thread
that
processes USRP data to eliminate overruns and data processing hiccups
caused
by window management and display events without noticeable impact on GUI
responsiveness. I think the only option on Linux is to use realtime
priority, which requires root access; I don’t know if this affects GUI
responsiveness.

My impression is that Windows isn’t so good if you need low latency, but
I
can’t quantify (or even verify) that.

Hi,

I suggest you run partition magic and divide your hard disk into a new
partition and install Ubuntu in the new partition. In this way, you can
keep
your Vista and run gnuradio safely in Linux.

On the ubuntu live cd (the installation CD) use gparted. It is already
there and ready for that purpose without having to resort to “your
favorite bittorrent copy” of partition magic.
