Sep 19, 2018 - Installing software

Load modules

Add to ~/.bash_profile:

module load intel/intel-18\n
module load intelmpi/2018.1.163
module load openmpi/3.0.0-intel-18
module load gcc/7.3.0
module load python/2.7.14
#necessary to have Intel MPI working on CITA cluster
export I_MPI_FABRICS=shm:tcp
export I_MPI_TCP_NETMASK=10.5.0.0

On Niagara, instead add

module load intel/2018.3
python/3.6.4-anaconda5.1.0
module load intelmpi/2018.3

Install FITSIO

Download from [1]

Run ./configure

Run make

Install Healpix

Download from [2]

Run ./configure

Choose default choices unless otherwise stated.

Choose 3 (Fortran), ifort (F90 compiler), folder in which FITSIO was installed in the previous step (location of the cfitsio library).

Choose 4 (C++), 1 (basic_gcc configuration for C++ compilation)

Choose 5 (Python)

Choose 0 (exit)

Add Healpix initialization to ~/.bash_profile (see output after Fortran initialization). Source the file to reflect the changes.

Run make

Go for a coffee

P.S.: On Niagara, in the Fortran section of configure choose icc as the C compiler

Install modified Lenspix

Clone git repo https://github.com/louis-pham/modified_lenspix

Run make in src

As a test, run python lens.py test_maps/kappa_map.fits test_maps/primary_alm.fits test_maps/phi_trial.fits test_maps/lensed_trial.fits -np 8

Actually, on the first attempt the code started with Creating zero map..., then did a bunch of other things and then got stuck (or so it seemed). After termination and restarting all proceeded normally.

P.S.: On Niagara, it is necessary to replace all the print X by print(X) to be compliant with Python3

We also had to perform following changes in Makefile:

• Add cfitsio = /home/r/rbond/motloch/useful_software/cfitsio
• Change the Fortran flags by editing cfitstio -L and adding curl to

F90FLAGS = $(FFLAGS) -I$(healpix) -I$(healpix)/include -L$(cfitsio) -L$(healpix)/lib $(LAPACKL) -lcfitsio -lcurl <\code>
