Resuming from Last Run

brains supports resuming from last run. The adopted DNest sampling code CDNest outputs a number of sampling snapshots with a name as restart_dnest.txt_xxx for continuum reconstruction, restart1d_dnest.txt_xxx for 1D and restart2d_dnest.txt_xxx for 2D RM analysis. Here, xxx mean the steps when the snapshot is saved. Such snapshots are saved every one fifth of MaxNumberSaves.

For 2D RM analysis, rename the above files as

cp restart2d_dnest.txt_xxx restart2d_dnest.txt
#namely, just remove "_xxx" in the file name

Then change the step numbers in the option files (e.g., param/OPTIONS2D) and resume from last run by adding an option “-r” as

mpiexec -n np ./brains para/param -r

where “np” is the number of cores. It must be the same as the number of cores used in last run.
