Investigate pinnochio and ezmock #18

Closed maho3 closed 4 months ago

maho3 commented 7 months ago

This task is to investigate the following mock generation codes for their possible utility as a baseline for Go Big:

These are used in Euclid and DESI (?), respectively. We should figure out to what halo resolution they resolve, and how fast they are relative to PM simulations.

To build pinnochio on infinity, first load openmpi

module load openmpi/5.0.3-gnu

After cloning pinnochio from https://github.com/pigimonaco/Pinocchio, edit the Makefile to be compatible with infinity:

ifeq ($(SYSTYPE),"infinity")
CC          =  mpicc
CDEBUG      = -ggdb3 -Wall
COPTIMIZED  = -O3 -Wno-unused-result
FFTW_LIBR   = -L/softs/fftw3/3.3.10-gnu-mpi/lib -lfftw3_mpi -lfftw3
FFTW_INCL   = -I/softs/fftw3/3.3.10-gnu-mpi/include
MPI_LIBR    = -L/softs/openmpi/5.0.3-gnu/include
MPI_INCL    =
GSL_LIBR    = -lgsl -lgslcblas -lm
GSL_INCL    = -I/usr/include
endif

Also change the SYSTYPE argument to be "infinity" and ensure the "-DWHITENOISE" option is enabled. Building with make clean; make should then work. Before running the executable pinnochio.x, you must also run

export LD_LIBRARY_PATH=/softs/fftw3/3.3.10-gnu-mpi/lib:$LD_LIBRARY_PATH

to enable pinnochio to access the fftw3_mpi library.

Pinocchio implemented.
