v1 v2 43 43 }}} 44 44 45 6) Run the MAC-TEST to obtain your processor performance: 46 {{{ 47 sudo runcf -t NOFCORES 1000000 48 }}} 49 replacing NOFCORES with the number of cores in your processor. You should see something like this: 50 {{{ 51 child 2: 1344192127:118 -> 1344192127:1561 diff: 0:1443 693 MMACS 52 child 3: 1344192127:117 -> 1344192127:1561 diff: 0:1444 692 MMACS 53 child 1: 1344192127:214 -> 1344192127:1597 diff: 0:1383 723 MMACS 54 child 0: 1344192127:214 -> 1344192127:1597 diff: 0:1383 723 MMACS 55 parent: 1344192126:183204->1344192127:3329 diff: 0:820125 56 }}} 57 58 Now set the ''mops'' field in /usr/local/etc/platform.conf option to the MMACS obtained in the test. 59 45 60 == Running the Demo application == 46 61 … … 70 85 Which set the fft size to 256 and 512 tones respectively (4 and 8 MHz bandwidth). By default, the framework will use one processor only from your computer. If you have a multi-core processor, edit the 'nof_cores' option in /usr/local/etc/platform.conf file. In our tests, the OFDM application runs perfectly in a 2.5 GHz Intel processor using one core only. The 512 mode produces frequent real-time faults (printed stdout). This mode works correctly in a dual-processor environment. 71 86 72 == U sing the USRP ==87 == USRP == 73 88 74 89 If the UHD driver is installed before running ALOE's configure script, the option dac=uhd in /usr/local/etc/platform.conf file allows ALOE to send samples to the USRP. Just edit the platform.conf file and run the OFDM-128 waveform from the ALOE command man. The device sampling frequency is automatically configured by ALOE. Since not all devices can work with the same sampling frequencies, the execution period (time-slot) can differ slightly from one set-up to another. … … 78 93 == Distributed Processing == 79 94 95 1) Download and install ALOE in two computers 96 97 2) Setup your network, making sure you have full TCP and UDP connectivity between both computers. 98 99 3) Edit file /usr/local/etc/xitf1.conf and replace 192.168.1.1 by the ip address of your MASTER node. 100 101 4) 102 103
