Hi Anders,

concerning moving geometries, if the 'moving' part is implemented via
parameterised volumes (and assuming the parameterisation is correctly
implemented, i.e. it is thread_safe), this will work in MT mode, as the
parameterised part gets automatically cloned in each thread.
If the moving part is implemented via normal placements, this depends
on the number of events you want to execute before a change to the
geometry applies (i.e. duration of a run); during the run the execution
can obviously happen in parallel.

Cheers, Gabriele
