## SC19 reproducibility

Please find in the folders `SC_paper_summit_runs` and `SC_paper_titan_runs` the inputs, scripts, and

executables used to produce the data reported in the Super Computing 2019 submission.

The runs for the new code were made using commit `7652c6956eaaa36ac375522b9571058c470ce47a`, while

commit `d25b256db2d61090963cd7b2975158557fd5f098` was used for the old version. Mind that only the

`main_dca` executable is guaranteed to work with the old code.

Only a subset of the original configuration were kept due to space reason. 

If running with more than 600 MPI ranks, the runtime will be reproducable, but the output

will not be bytewise, as it is equivalent of running an independent MC simulation with a 

different initial condition.
