Is there a module to autotune these values according to cpu/mem/ctxt

I think you're thinking of Jake's genetic algorithms (separate patch). They
tune the zaphod scheduler but bear in mind the limitation of such an
algorithm is they can only tune for one workload which means that if you have
two workloads running concurrently with different requirements, the other
will suffer.
Also, different schedulers per cpu could be rather useful.

I think that would be dangerous. However, different schedulers per
cpuset might make sense but it involve a fair bit of work.
I'm curious. How do you think different schedulers per cpu would be useful?
I don't but I think they MIGHT make sense for cpusets e.g. one set with
a scheduler targeted at interactive tasks and another targeted at server
tasks. NB the emphasis on might.
