Overview over the computational cost for the two inference methods.

Method	Computing time
Method	gen. TD & training	single inference
cINN ^(‡)	105 days	5 min
MCMC ^(†)	–	8.7 days
parallel MCMC ^(†)	–	12 h

Notes. ^(†) Run on a compute node containing 2 × 14-Core Intel Xeon Gold 6132 CPUs at 2.6 GHz. ^(‡) Run on a compute node containing 2 × 14-Core Intel Xeon Gold 6132 CPUs at 2.6 GHz and 10× Nvidia Titan Xp GPUs at 1.6 GHz.
