Hei, during recent experiments with the adaptive stepper in odeint I noticed that the step size used for each step can vary if I am using more than one thread at the same time (i.e. thread 1 can have a different step size than thread 2 when doing the same step). This is not suitable for my project, after the function calculating the right hand side relies on having the same step size for each thread.
Before starting deeper experiments with the adaptive steppers in PETSc, I therefore wanted to ask if those steppers synchronize the step size of the sub-steps between the different mpi processes at each step, or if not? Thanks! Regards, Roland
