description The latest development in ATLAS MC generator tunings will be discussed. Pythia 6 generators have been tuned with a variety of PDFs, and shower tunings to QCD jet structure has been performed. Pythia 8 tunes have been constructed for two different PDFs, and are primarily aimed at an optimal description of minimum bias, for use in pile-up simulation. Also tunes of Herwig+JIMMY were performed for the final time inside ATLAS. Interesting effects were observed in MPI simulation when using MC-adapted PDFs. The current focus of ATLAS tuning efforts will also be mentioned.
