Spatial constant rate jump #343

Vilin97 · 2023-09-03T04:42:37Z

Add spatial constant rate jump support.

NB: I have not implemented flattening for constant rate jumps, because it's unclear how to flatten constant rate jumps.

Implementation details:
In order to use constant rate jumps, the user is expected to pass in a JumpSet and two dependency graphs (reaction-reaction and reaction-species). The syntax is as follows:

rate1(u,p,t,site) = ...
rate2(u,p,t,site) = ...
affect1!(integrator,site) = ...
affect2!(integrator,site) =...
crjumps = JumpSet([ConstantRateJump(rate1, affect1!), ConstantRateJump(rate2, affect2!)])
# define prob, hopping_constants, spatial_system, and dependency_graphs
jump_prob = JumpProblem(prob, NSM(), crjumps, hopping_constants = hopping_constants,
            spatial_system = spatial_system , save_positions = (false, false), dep_graph = dep_graph, jumptovars_map = jumptovars_map)

Just use ConstantRateJump with `rate(u,p,t,site)`.

…e jumps.

Instead of passing the site into the affect and rate functions, we could store it in the aggregator and make an interface for users to access it via the integrator (which stores the aggregator). Something like get_current_site(integrator). Then this would work with old-style constant rate jump signatures. I don't know if we want that though.

The other big issue is I think there are going to be type stability issues without using FunctionWrappers on the rate and affect functions (since each function is its own type, every crj will be a different type).

For future consideration, do you know if storing the jumps in RxRates instead of within the aggregator directly results in an extra layer of indirection when accessing them (i.e. an extra pointer call)? If so, we might want to consider moving them up a level if that shows any performance benefit.

Suggested change

RxRates(num_sites::Int, cr_jumps::C) where {C} = RxRates(num_sites, SpatialMassActionJump(), cr_jumps)

I'd specify a type for C here or not include C at all. Generally a generic type like this would be suggested to just be dropped since it isn't being used (it may even give a warning in tests).

This isn't type stable is it? That is why we split the ConstantRateJump rates and affects in the non-spatial solvers and wrap them inside FunctionWrappers.
