Re: [Discuss-gnuradio] Reg : Simultaneous execution of two scripts

[sumitstop]

Tom I observed following :
I connected 3 usrp-1 and ran 3 scripts activate_usrp_1.sh, 2.sh, 3.sh
All were asked to execute at 44th second of any minute.
I also put a time stamp just after tb.start()

    try:
        tb.start()
        startTime = datetime.now()
        print "usrp_X started at time",
        print startTime

I got following
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* I also varied the order in which activate_usrp_1,2,3.sh were executed
which you can see

usrp_1 started at time 2013-03-08 02:58:44.519909
usrp_2 started at time 2013-03-08 02:58:44.752680

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I am not able to come up with any pattern of failure 
I also observed that my new usrp i.e. usrp_3 is a bit lazier than the old
ones regardless of the order of execution of activate_usrp_1,2,3.sh 
Probably the new one is equipped with SBX while the old ones are with
RFX2400 (just an observation)
