I agree with Ian - the OpenSolaris build is not ready
to be built in distributed or grid mode. Actually it is
a tough task to make distributed build effective.
Obviously it takes some time to distribute a job to
another system. If this time is bigger than to perform
this job locally, the total build time in parallel mode
will be less than in distributed or grid mode.
So, to win, we have to identify "big" parts, and distribute
them to the grid systems (where they will be done by
dmake in parallel mode). It is interesting task to try to
build OpenSolaris in grid mode faster than in parallel
mode, but I don't know if anybody tried to look at the
OpenSolaris build process from this point of view.
It (distributed mode) comes into its own with C++ where the individual
compiles take longer, although with the size of some of the ON files, I
would have though it would make an improvement.
I typically see 70% or so improvement over parallel with my stuff.
