Hi all! I am Tx/Rx a FM signal at the same time, but I can see a lot of SSSSS messages that mean my CPU cannot keep up with all frames generated by the USRP2 and drop most of them. However I have a quite new laptop with a CPU:Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz on Ubuntu 10.4
I guess that my laptop is enough to run my FM Tx/Rx and I wonder if I can balance the workload among all my four cores to see if my application improves (ethernet interface doens't drop any frame). Looking at other post of the mailing list I found: 1)"Try using numactl". Well, for me is not possible, after installing that library and running: :~$ numactl -s physcpubind: 0 1 2 3 No NUMA support available on this system. 2)"Look at the output of cat /proc/cpuinfo "physical id" indicates which cores are in which sockets" In all four processors physical id : 0 Furthermore whe I execute top command I can see: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3022 root 20 0 238m 66m 45m S 166 3.6 3:32.12 python Is my GRC file only executing in one core? How can I find it out? Any idea to fix it? Many thanks, Jorge
