[Users] Segmentation Fault with CarpetReduce

[Garrison, David]

Hello,

It is a custom code so I am attaching the part I used to do the reductions instead.

handle = CCTK_ReductionHandle("average");
ierr = CCTK_Reduce(cctkGH, -1, handle, 1, CCTK_VARIABLE_REAL, &scale_factor, 1, CCTK_VarIndex("MHD_Analysis::aa_out_avg"));
ierr = CCTK_Reduce(cctkGH, -1, handle, 1, CCTK_VARIABLE_REAL, &utime, 1, CCTK_VarIndex("MHD_Analysis::univ_age"));

DG,
    could you share the parameter file you are using? So that we may have a better look at the problem.

Thanks,
Bruno

Hello,

Whenever I set the number of ghost zones to 1, I get segmentation faults from my reduction operations.  This wasn’t an issue with Pugh or when I use 2 or more ghost zones with Carpet.  Has anyone else had this problem?
