Comment (by rhaas):

 Replying to [comment:2 rhaas]:
 > Currently, when {{{other_timelevels}}} is 1 the code in ML_BSSN_Helper
 will disable checkpointing, prolongation and persistency. Though looking
 at the code at least the prolongation part is stated to be handled by
 Kranc itself (Erik and Ian would know details it seems).

 I just tried this with the attached qc0_mclachlan.par file and Kranc (at
 least in the release branch where the comment appears) does not seem to
 turn off prolongation:
 {{{
 ERROR from host 127.0.0.1 process 0
   while executing schedule bin (none), routine (no thorn)::(no routine)
   in thorn CarpetLib, file configs/sim/build/CarpetLib/ggf.cc:334:
   -> The variable "ML_BSSN::cS" has only 1 active time levels, which is
 not enough for boundary prolongation of order 2
 }}}
