Alternatively, you could also use a custom macro such as `@threaded` from  
[Overhead of `Threads.@threads` - #23 by ranocha](https://discourse.julialang.org/t/overhead-of-threads-threads/53964/23) for development. Then, you will basically run the serial code without further allocations when starting Julia with a single thread, which can be helpful for development. We did that before switching to `@batch` in Trixi.jl.
