Hi Wuyang: I am not sure if the design was actually implemented. At least, I am not aware of such simulators.
If you want to simulate with your own framework, one possibility is to run multiple agents with fake resources on the same (or a few) node. Alternatively, we have a lightweight benchmark test suite inside Mesos for the allocator: https://github.com/apache/mesos/blob/master/src/tests/hierarchical_allocator_benchmarks.cpp#L128 You can easily specify agent and framework <https://github.com/apache/mesos/blob/dcd73437549413790751d1ff127989dbb29bd753/src/tests/hierarchical_allocator_benchmarks.cpp#L70-L116> profiles and spawn them. However, currently, it is not possible to directly plug-in your own framework. Here is an example simulation <https://github.com/apache/mesos/blob/dcd73437549413790751d1ff127989dbb29bd753/src/tests/hierarchical_allocator_benchmarks.cpp#L324-L328> that uses the fixture. You can extend the framework profile and fixture to either encode more behaviors per your preference. In both cases, the Mesos default allocator is used. You can change the allocation algorithm by using your own allocator implementation. Hope it helps. -Meng On Tue, Jul 9, 2019 at 5:06 PM uyang Zhang W <[email protected]> wrote: > Dear all, > > I developed a framework and would like to test the scheduling algorithm by > simulating it in a large scale environment. > > I found an old doc at > https://docs.google.com/document/d/1Ygq9MPWrqcQLf0J-mraVeEIRYk3xNXXQ0xRHFqTiXsQ/edit#. > It basically satisfies all the requirements.
