Hi all, I am facing the problem of speeding up ns-2 simulations. I have my own agent and I do simulation on wireless networks with up to 600 nodes. I don't use any routing agent nor I use traffic generators. Assuming that my agent is internally well optimized, I tried to reduce the number of "things" that ns-2 does in order to avoid unnecessary computation. The first thing was to I avoid the use of GOD. Second, I disabled all the tracing from my Tcl script. Unfortunately I could not disable the creation of the trace file, i.e., I could not get rid of the following lines:
set tracefd [open wireless-out.tr w] $ns_ trace-all $tracefd without getting an error. I would like to know 1) if I can totally disable any internal tracing 2) if there are other things that I can disable to make ns-2 run faster either in the C part of the simulator or though Tcl script. Thank you in advance, Regards Michele Battelli
