[yocto] Icecc configuration on mpich ?

[Riko Ho]

Dear Yocto Team Member,

Yes, I'm confuse about those,

And reading about Icecc now.

Icecc is the right way for distributing compilation for my bitbake, 
correct me ?

I read about :

26.50.
icecc.bbclass  on Yocto manual, but I'm not sure on how to use it yet ?

Thanks
