Hi all,
I am testing an application, which receives data from usrp. The
datarate is 2M, and samples_per_symbol is 2, decimation is 16. I am
using a PC, with Ubuntu 8.10, intel pentium 4 cpu 2.40G, and 768M Memory.
But the shell displays uOuOuO when running. I know it means usrp
overrun. I am not opening any large programs except internet brower.
Because i cannot change the decimation and sample_per_symbol, What
method can i use to avoid usrp overrun? Any help in this regard would
be highly appreciated, and thank you for your help!

Lizhao
Hi Lizhao,
Have a look in "/proc/cpuinfo" to see your current cpu- speed, Ubuntu
8.10 introduced a frequency- scaling thing, which sometimes messes with
you and set your cpu to work at a lower clock- speed.
If that doesn't work, you could probably try to elevate your programs
scheduling, have a look at "gruel".
