PassiveFW_versionstable change another parallel computing monitoring tool, simple but more stable.

I develop the PassiveFW package mainly for modeling active and passive seismic full wavefields with small scale geometry in layered media.
This package is mainly based on stiffness matrix method and discrete wavenumber method. 
main_active_shotgather.m show an example of active seismic wavefields in layered media due to a point load of Ricker wavelet.
main_passive_noise.m give an example of ambient noise with roadside geometry.


Just remember the time step dt is the key parameter that affect calculation speed.
A typical roadside example takes 50 minutes on a 4-core computer, but less than ten minutes on a 40-core computer. 

I will add more detailed instructions once I finish it.

For any suggestion, question or bug-fix, please don't hesitate to contact me.
