Hello,
<div><br>
</div>
<div>It is a custom code so I am attaching the part I used to do the reductions instead.</div>
<div><br>
</div>
<div>
<div>handle = CCTK_ReductionHandle("average");</div>
<div>ierr = CCTK_Reduce(cctkGH, -1, handle, 1, CCTK_VARIABLE_REAL, &scale_factor, 1, CCTK_VarIndex("MHD_Analysis::aa_out_avg"));</div>
<div>ierr = CCTK_Reduce(cctkGH, -1, handle, 1, CCTK_VARIABLE_REAL, &utime, 1, CCTK_VarIndex("MHD_Analysis::univ_age"));</div>

<div> could you share the parameter file you are using? So that we may have a better look at the problem.</div>

<div>Hello,
<div><br>
</div>
<div>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?</div>
