Dear Iosif,

I hope this message finds you well.

I'm not sure you already got a reply, but in case you haven't, my understanding is that placeholders like @FOO@ are there to indicate things you need to change yourself, manually.

So when you see something like:

#SBATCH -A @ALLOCATION@

then it means you should replace @ALLOCATION@ with the name of your allocation in the specific cluster.

Someone else can correct me if this is not correct, but that's how I usually handle these.

Cheers,
Leo

Hi,

I have been following this document, https://einsteintoolkit.org/seminars/2022_02_24/index.html , to set up ET on my cluster, working also on some example configuration files.

While preparing the submit and run scripts, I wanted to check the description of the @FOO@ macros that SimFactory uses.

I checked these places but found no information.

  *
https://simfactory.bitbucket.io/simfactory2/userguide/ (no mention of macros)
  *
https://docs.einsteintoolkit.org/et-docs/Simulation_Factory_Advanced_Tutorial (1 mention of the @USER@ macro and a pointer to a section #Macros<https://docs.einsteintoolkit.org/et-docs/Simulation_Factory_Advanced_Tutorial#Macros> that seems missing)
  *
https://docs.einsteintoolkit.org/et-docs/Configuring_a_new_machine (there is no information on the submitscript and runscript)

So I would like to ask:

If e.g. I have this line in my submitscript:
#SBATCH -A @ALLOCATION@

Where is @ALLOCATION@ "read" from?

My guess is that this is specified in the .ini file in this line:
allocation = <project_account>

Could you confirm if this is the case?

Is there another source of documentation (that I might have missed) describing what these @FOO@ placeholders do?

Best regards,
Panagiotis

Hi people,

I have used ReadInterpolate successfully for different applications in the past. I'm now trying to use it to interpolate onto a new grid that has 5 ghost zones i.e.:

CoordBase::boundary_size_x_lower     = 5
CoordBase::boundary_size_y_lower     = 5
CoordBase::boundary_size_z_lower     = 5
CoordBase::boundary_size_x_upper     = 5
CoordBase::boundary_size_y_upper     = 5
CoordBase::boundary_size_z_upper     = 5
Driver::ghost_size                   = 5
GRHydro::GRHydro_stencil             = 5
But I'm getting this error:

CCTK_Proc569.err <==
  while executing schedule bin ReadInterpolate_ReadData, routine ReadInterpolate::ReadInterpolate_Read
  in thorn ReadInterpolate, file /home/mvxcombi/ET_Zelmani/Cactus/arrangements/EinsteinInitialData/ReadInterpolate/src/read.c:559:

Writing backtrace to AIC_interp/backtrace.569.txt
The original grid has 3 ghost zones. I'm using the following parfile:
# What to interpolate
# -------------------
ReadInterpolate::files                        = "checkpoint.chkpt.it_335925"
ReadInterpolate::max_number_of_read_variables = 30
ReadInterpolate::only_these_datasets          = ":Y_e, :rho, :temperature, :vel, :Ax, :Ay, :Az, :psi6phi, :kxx, :kxy, :kxz, :kyy, :kyz, :kzz, :gxx, :gxy, :gxz, :gyy, :gyz, :gzz, :betax, :betay, :betaz, :alp"
ReadInterpolate::minimum_reflevel             = 0     # Default
ReadInterpolate::maximum_reflevel             = 1000  # Default

# Interpolator settings
# ---------------------
ReadInterpolate::epsilon                 = 1.e-12 #2  # Default
ReadInterpolate::interpolator_half_width = -1      # Default, use cctk_nghostzones
ReadInterpolate::interpolator_name       = "Lagrange polynomial interpolation"
ReadInterpolate::interpolator_pars       = "
    order = 3
    boundary_off_centering_tolerance = {1. 1. 1. 1. 1. 1.}
    boundary_extrapolation_tolerance = {1.e-12 1.e-12 1.e-12 1.e-12 1.e-12 1.e-12}
"

# Fixing the read-in data
# -----------------------
ReadInterpolate::shift_read_datasets_by[0] = 0.
ReadInterpolate::shift_read_datasets_by[1] = 0.
ReadInterpolate::shift_read_datasets_by[2] = 0.

ReadInterpolate::enforce_symmetries_after_reading = no  # Default
ReadInterpolate::fix_cell_centered_origins        = no  # Default

Any suggestions on how to solve this issue?

Thanks a lot!!
