Context. Stellar spectral synthesis is essential for various applications,ranging from determining stellar parameters to comprehensive stellarvariability calculations. New observational resources as well as advancedstellar atmosphere modelling, taking three dimensional (3D) effects fromradiative magnetohydrodynamics calculations into account, require a moreefficient radiative transfer.  Aims. For accurate, fast and flexible calculations of opacity distributionfunctions (ODFs), stellar atmospheres and stellar spectra we developed anefficient code building on the well-established ATLAS9 code. The new code alsopaves the way for an easy and fast access to different elemental compositionsin stellar calculations.  Methods. For the generation of ODF tables we further developed thewell-established DFSYNTHE code by implementing additional functionality, and aspeed-up by employing a parallel computation scheme. In addition, the linelists used can be changed from Kurucz's recent lists. In particular, weimplemented the VALD3 line list.  Results. A new code, the Merged Parallelised Simplified ATLAS is presented.It combines the efficient generation of ODF, atmosphere modelling and spectralsynthesis in local thermodynamic equilibrium, therefore being an all-in-onecode. This all-in-one code provides more numerical functionality and issubstantially faster compared to other available codes. The fully portableMPS-ATLAS code is validated against previous ATLAS9 calculations, the PHOENIXcode calculations, and high quality observations.
