Hello,
I am trying to switch to carpet mercurial. I compiled two executables, identical except for the Carpet thorns, one with thorns from the git repository and the other with thorns from the hg repository.
The BBH simulations runs with the git version, but (with the same parfile) it fails with the hg version:
... INFO (CarpetReduce): Simulation domain volume: 512000 INFO (CarpetReduce): Reduction weight sum: 511999.999154925 WARNING[L1,P0] (CarpetReduce): Simulation domain volume and reduction weight sum differ Memory statistics from CarpetLib: Current number of objects: 2611 Current allocated memory: 649 MB Maximum number of objects: 2.63e+03 Maximum allocated memory: 652 MB Current administrative memory: 2.79 MB Total allocated used system memory: 665 MB Total allocated free system memory: 17.6 MB gh::allmemory: 708688 dh::allmemory: 1301208 th::allmemory: 26608 ggf::allmemory: 576000 gdata::allmemory: 182224 INFO (IsolatedHorizon): Low Spin < 1e-3 !

I am running on damiana, with the same configuration options and qsub scripts for the two executables. When switching from git to hg, should I change, add, or remove some parameter?
Here is a list of the carpet parameters (and a few others) that I set in my parfiles:
ActiveThorns" Carpet CarpetIOScalar CarpetIOASCII CarpetIOBasic CarpetIOHDF5 CarpetInterp CarpetLib CarpetMask CarpetReduce CarpetRegrid2
Parameters:
Carpet::domain_from_coordbase = yes Carpet::max_refinement_levels = 9 CarpetRegrid2::num_centres = 2 CarpetRegrid2::num_levels_1 = 9 CarpetRegrid2::position_x_1 = 4 CarpetRegrid2::radius_1 [1] = 100.0
etc.
Carpet::time_refinement_factors = "[1,1,1,2,4,8,16,32,64]"
Carpet::use_buffer_zones = yes Carpet::prolongation_order_space = 5 Carpet::prolongation_order_time = 2 Carpet::regrid_in_level_mode = yes Carpet::regrid_during_initialisation = no CarpetRegrid2::regrid_every = 256 Carpet::init_fill_timelevels = yes InitBase::initial_data_setup_method = "init_all_levels" CarpetTracker::surface [0] = 0 CarpetTracker::surface [1] = 1 MoL::ODE_Method = "rk4" MoL::MoL_Intermediate_Steps = 4 Carpet::num_integrator_substeps = 4 MoL::MoL_Num_Scratch_Levels = 1 CarpetMask::excluded_surface [0] = 2 CarpetMask::excluded_surface_factor [0] = 1. CarpetMask::excluded_surface [1] = 3 CarpetMask::excluded_surface [2] = 4 Carpet::poison_new_timelevels = yes Carpet::check_for_poison = no CarpetLib::poison_new_memory = yes CarpetLib::poison_value = 200 Carpet::output_timers_every = 768 CarpetLib::print_timestats_every = 768 CarpetLib::print_memstats_every = 768
