Installation †Here how to compile Quantum-ESPRESSO 6.1 on ohtaka at ISSP, the University of Tokyo. First of all, make sure that the modules are loaded properly. In this tutorial, the following modules are used: intel_mpi/2019.5.281 intel_compiler/2019.5.281 intel_mkl/2019.5.281 To load the above modules, the following commands should be executed: module purge module load intel_mpi/2019.5.281 module load intel_compiler/2019.5.281 module load intel_mkl/2019.5.281 The reason why the old compiler and libraries are used is because on AMD nodes, the code build using ifort 2020 can crash when thousands of cores are used. Let us first make directories for source codes, pseudopotentials, and calculations for Quantum-ESPRESSO in the home directory, for e.g. $ mkdir -p QE/src $ mkdir -p QE/pseudo $ mkdir -p QE/out Obtaining the code †In the ${HOME}/QE/src directory, type $ git clone -b 'qe-6.1' --depth 1 https://gitlab.com/QEF/q-e.git qe-6.1 If "qe-6.6" is not specified, "q-e" is generated. One can also do $ wget https://gitlab.com/QEF/q-e/-/archive/qe-6.1/q-e-qe-6.1.tar.bz2 and untar $ tar jxf q-e-qe-6.1.tar.bz2 $ mv q-e-qe-6.1 qe-6.1 Configure and build †QE †In qe-6.1, execute the following $ MPIF90=mpiifort DFLAGS='-D__OPENMP -D__FFTW3 -D__MPI -D__SCALAPACK' SCALAPACK_LIBS='-L${MKLROOT}/lib/intel64 -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64' IFLAGS='-I$(TOPDIR)/include -I../include/ -I/opt/intel/mkl/include -I${MKLROOT}/include/fftw' ./configure --enable-openmp Then type $ make pw Other programs can be found by just typing $ make I usually build PW as well as PP by typing $ make pw pp If you like to perform phonon calculations do $ make ph |
