Compiler optimisation flags can be quite helpful in bringing the (sometimes huge) duration of your OMNeT++ simulations to an acceptable level. Using a compute cluster can help, but even then the execution of a single process can take many hours for large networks. So let’s look at how you compile your code; I got a speed-up of approximately 10 times on some of my simulations. Read the rest of this entry »
OMNeT++ simulations can export an eventlog. Though the manual is pretty complete about it, I’ll summarise it here. Read the rest of this entry »
After an update of GCC (on Kubuntu 11.10) this error shows up when running simulations after recompilation.
