Hi there, i am trying to play around further with the tools in
gnuradio and was surprised that when i use usrp_fft.py -f 27.195M
everything worked as expected, but as soon as i added the -W or -S
to the command nothing works anymore.
I just updated to the latest SVN trunk, complied and installed
everything. ‘usrp_fft.py’ as now found in /usr/local/bin works OK
for me on OSX 10.4.10 and the latest MacPorts and Apple updates, with
no “-W” or -S". Both the “-W” and “-S” options work, but do hang
regularly. In my testing, the hanging is directly related to the CPU
utilization. On my Intel-iMac with Core 2 Duo, once the app thread
reaches > 100% CPU utilization, the thread hangs (NB: the ‘100%’
number is approximate; I’ve seen ‘top’ report back up to 103% without
hanging immediately, but never > 104% without hanging). As I only
have access to dual-processor Macs (both PPC and Intel), I can’t say
what happens on single-processor Macs.
Does someone notice the same prob in osx? Is there a solution?
I haven’t been playing around with the default GNU Radio examples
recently, so I hadn’t noticed this behavior. I know of no solution
at this time, but I will investigate it as time allows. - MLD
