Parallelism across the time
In the first version of EpODE, a Jacobi waveform relaxation method
was implemented. In this case, at the first stage,
the system of n differential equations
is decoupled into n independent equations which can be computed
in n separated processes (see parallelism across system).
At the next step, some n new equations are integrated separately, and
the difference between the old and the new solutions must be computed.
If this difference in a given norm is under the admissible error level,
the solution computation main process is stopped, otherwise a new stage
is started.
Example for the system B1.
