I heard from somewhere that it is possible to write and add a custom process
scheduler to the Solaris kernel without having to recompile the whole kernel. I
am going to run simulations with different modified schedulers in a full system
simulator and not having to recompile the kernel would greatly improve the
speed of things.
Does anybody know if this is true or not and, if it is, where to find some
documentation about this feature?
It is possible to change the dispatch tables of the scheduling classes.
See dispadmin(4), ts_dptbl(4).
However you might be better off just using the Fair Share Scheduler, see
FSS(7) and http://docs.sun.com/app/docs/doc/817-1592/6mhahuojp?a=view
for how this works. It is tunable based on shares. See the project(4)
concept for one way to use this to give different applications different
resource allocations.
