I don't see how this line could be triggered when the number of boundary points is zero.

Can you output bnd_points[2*d+f] and cctk_lsh[d] (both are ints) before the error message, or look at them in a debugger?

What is the error message you are seeing?

Hello,

It seems that CarpetReduce does not allow me to run the executable with the following parameter choice:

CoordBase::boundary_size_x_upper     = 0 CoordBase::boundary_size_y_upper     = 0 CoordBase::boundary_size_z_upper     = 0

CoordBase::boundary_shiftout_x_upper = 0 CoordBase::boundary_shiftout_y_upper = 0 CoordBase::boundary_shiftout_z_upper = 0

The offending line was commented out on Mac I I have forgotten about it. Is there a reason I am overlooking of why I cannot have this combination of paramentes?

Maria

The respective check (in line 96) ensures that the number of boundary points is non-negative, and that it is not larger than the total number of points on this process. Zero boundary points satisfy both properties.

Can you check that this condition reads indeed

if (bnd_points[2*d+f] < 0 || bnd_points[2*d+f] > cctk_lsh[d]) {

on both computers? If so, something is strange on the Ubuntu system.

Hello,

The CarpetReduce thorn does not allow boundary_size = 0, although the Coordbase thorn provides this capabilitiy. The error is: WARNING level 0 in thorn CarpetReduce processor 0 host babiuc-9  (line 96 of /home/babiuc/EinsteinToolkit/Cactus/configs/fourierwave/build/CarpetReduce/mask_coords.c):  -> Illegal number of boundary points WARNING level 0 in thorn CarpetReduce processor 0 host babiuc-9  (line 96 of /home/babiuc/EinsteinToolkit/Cactus/configs/fourierwave/build/CarpetReduce/mask_coords.c):  -> Illegal number of boundary points cactus_fourierwave: /home/babiuc/EinsteinToolkit/Cactus/configs/fourierwave/build/Carpet/helpers.cc:272: int Carpet::Abort(const cGH*, int): Assertion `0' failed.

This happens on a Ubuntu. On a MacOS, the problem seems to be overlooked. The parameter file is attached.

thanks, Maria
