Installation †

Here how to compile PIMD version 2.3.0 with the Quantum-ESPRESSO on the smith cluster system is described.
To use with PIMD, we are forced to use QE 6.2.1. See also the link page , on which this page heavily rely.

Let us suppose the source code is located at

~/PIMD/src

In the home directory make the directory and change directory as

$ mkdir -p PIMD/src/pimd-2.3.0
$ cd PIMD/src/pimd-2.3.0

Then download the source code by typing

$ wget https://ccse.jaea.go.jp/software/PIMD/download/pimd.2.3.0.tar

unntar it

$ tar xvf pimd.2.3.0.tar

and create a directory to compile the program

$ mkdir compile

All the source files are copied from the source directory as

$ cd compile

and

FFLAGS_NOMAIN   = -nofor_main -xSSE4.2 -axCOMMON-AVX512,CORE-AVX512,CORE-AVX2,CORE-AVX-I,AVX

$ cp ../source/* .

In the compile directory, modify "makeifle" as follows:

• Compiler

  FCMP = mpiifort

• Compiler options

  OPTS   =  -O3 -g -traceback \
            -xSSE4.2 -axCOMMON-AVX512,CORE-AVX512,CORE-AVX2,CORE-AVX-I,AVX \
            -static-intel -qopenmp \
            -I ${MKLROOT}/include/fftw -w

• Compiler options for QE (should be consistent with QE, which will be compiled later)

  LIBMKL = -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64 \
           -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core

Then generate modules necessary to compile the patched version of QE

$ make common_variables.o

Then go to the library directro

$ cd ../lib/qe

and download the QE source code:

$ wget https://github.com/QEF/q-e/archive/qe-6.2.1.zip

Unzip and apply the patch modified personally by myself

$ unzip qe-6.2.1.zip
$ patch -p0 < qe-6.2.1_to_pimdlib_new.patch

Then buld QE (actually library, not pw.x) as follows:

• Configuration Execute the following

  MPIF90=mpiifort DFLAGS='-D__OPENMP -D__FFTW3 -D__MPI -D__SCALAPACK' FFT_LIBS=-lfftw3 SCALAPACK_LIBS='-lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64' ./configure --enable-openmp

  and modify the make.inc as follows:

  FFLAGS         = -O2 -assume byterecl -g -traceback -qopenmp -xSSE4.2 -axCOMMON-AVX512,CORE-AVX512,CORE-AVX2,CORE-AVX-I,AVX

• Build

  $ make pw

Finally we build PIMD by simply executing the followings:

$ cd ../../../compile
$ make
