There's no reason for each of these things to be a _task_.

They should each be in separate _packages_, and be separate _objects_,
but not _tasks_.

Tasks are only needed for controlling timing, and then you need more
than one task only when there are truly asynchronous events. Or if you
want to gain speed by using parallel processors.

In the system you describe, there are bunch of calculations, that can
be done correctly if they are done serially.

Since you talk about multiple processors, you should have one task per
processor, and portion the computations among the tasks.
