Namespaces
namespace	autopas
	This is the main namespace of AutoPas.
namespace	autopas::utils
	In this namespace some helper classes and functions can be found used inside of AutoPas.
namespace	autopas::utils::AutoPasConfigurationCommunicator
	Provides several functions for handling configurations among mpi ranks.

Typedefs
using	autopas::utils::AutoPasConfigurationCommunicator::SerializedConfiguration = std::array< std::byte, serializedConfigurationSize >
	Type definition for the serialization of configurations.

Functions
void	autopas::utils::AutoPasConfigurationCommunicator::distributeRanksInBuckets (AutoPas_MPI_Comm comm, AutoPas_MPI_Comm *bucket, double smoothedPDBinStdDevDensity, double smoothedPDBinMaxDensity, double MPITuningMaxDifferenceForBucket, double MPITuningWeightForMaxDensity)
	Distribute ranks in buckets, which contain only ranks with similar scenarios.

std::vector< Configuration >	autopas::utils::AutoPasConfigurationCommunicator::deserializeConfigurations (const std::vector< std::byte > &configurationsSerialized)
	Deserialize a vector of bytes into a vector of configurations.
Configuration	autopas::utils::AutoPasConfigurationCommunicator::findGloballyBestConfiguration (AutoPas_MPI_Comm comm, Configuration localOptimalConfig, long localOptimalTime)
	Handles communication to select the globally best configuration.
std::vector< Configuration >	autopas::utils::AutoPasConfigurationCommunicator::gatherConfigurations (AutoPas_MPI_Comm comm, const std::vector< Configuration > &localConfigurations, int root)
	Gather the configuration vectors of all ranks in the communicator into one vector at the root process.
