Compiling USER-GFMD to LAMMPS-10Mar21 with OpenMPI and GNU

Prerequisites

  • openmpi-3.1.4
  • gnu-6.5
  • m4-1.4.18
  • gmp-6.1.0
  • mpfr-3.1.4
  • mpc-1.0.3
  • isl-0.18
  • gsl-2.1
  • python-3.6.9
  • fftw-3.3.8

Download the lammps.10Mar2021.tar.gz from https://download.lammps.org/tars/

Step 1: Untar LAMMPS

% tar -zxvf lammps-10Mar2021.tar.gz

Step 2: Go to $LAMMPS_HOME/src. Make Packages. I will only need kspace and USER-GFMD.

% make yes-kspace
% make pi
% make ps

Step 3: Preparing Green’s function molecular dynamics (GFMD) code on LAMMPS. For more information on the website, https://github.com/Atomistica/user-gfmd

% cd $LAMMPS_HOME
% git clone https://github.com/Atomistica/user-gfmd.git

You should see a directory called user-gfmd in your $LAMMPS_HOME. Rename it to uppercase

% mv user-gfmd USER-GFMD

Copy the USER-GDMD to the $LAMMPS_HOME/src and
Make the package

% cp USER-GFMD to src
% make yes-user-gfmd

Step 4: Edit the Makefile.g++_openmpi

% vim $LAMMPS_HOME/src/MAKE/OPTIONS/Makefile.g++_openmpi
FFT_INC =       -DFFT_FFTW3 -I/usr/local/fftw-3.3.8-gcc6/include
FFT_PATH =      -L/usr/local/fftw-3.3.8-gcc6/lib
FFT_LIB =        -lfftw3

The -DFFT_FFTW3 was important or I will get error like 

mpicxx -std=c++11 -g -O3 -DLAMMPS_GZIP -DGFMD_FFTW3 -DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX=1 -I/usr/local/fftw-3.3.8-gcc6/include -c ../nonperiodic_stiffness.cpp
../nonperiodic_stiffness.cpp:199:4: error: #error NonperiodicStiffnessKernel requires FFTW3
#error NonperiodicStiffnessKernel requires FFTW3
^~~~~
make[1]: *** [nonperiodic_stiffness.o] Error 1

Step 5: Compile LAMMPS

% make clean-all
% make g++_openmpi

You should have binary called lmp_g++_openmpi. Do a softlink

% ln -s lmp_g++_openmpi lammps

Make and Run USER-GFMD Units Tests

% cd src/USER-GFMD/
% make unittests
% ./unittests
[==========] Running 23 tests from 5 test cases.
[----------] Global test environment set-up.
[----------] 5 tests from CrystalSurfaceTest

[       OK ] CrystalSurfaceTest.fcc100_neighbor_shells (0 ms)
[----------] 5 tests from CrystalSurfaceTest (12 ms total)
.....

Run Tests

% cd src/USER-GFMD/tests
% sh run_tests.sh ../../lmp_g++_openmpi

I had some errors, but it did not look critical. Tests were run without failures

.....
.....

Error: Too many elements extracted from the MEAM Library on LAMMPS

If you encounter an errors similar

ERROR: Too many elements extracted from MEAM library (current limit:5 ). Increase 'maxelt' in meam.h and recompile. 
Last command: pair_coeff     * * library.alloy2.meam .............................

Move to /usr/local/lammps-29Oct20/src/USER-MEAMC/meam.h and /usr/local/lammps-29Oct20/src/meam.h. Edit line 22. The default value is #define maxelt 5

#definte maxelt 6

Recompile the lammps. Go to /usr/local/lammps-29Oct20/src

% make clean-all
% make g++_openmpi -j 16

No MEAM parameter file in pair coefficients Errors in LAMMPS

If you are encountering errors like, you may want to check 

ERROR: No MEAM parameter file in pair coefficients (../pair_meamc.cpp:243)

When a pair_coeff command using a potential file is specified, LAMMPS looks for the potential file in 2 places. First it looks in the location specified. E.g. if the file is specified as “niu3.eam”, it is looked for in the current working directory. If it is specified as “../potentials/niu3.eam”, then it is looked for in the potentials directory, assuming it is a sister directory of the current working directory. If the file is not found, it is then looked for in one of the directories specified by the LAMMPS_POTENTIALS environment variable. Thus if this is set to the potentials directory in the LAMMPS distribution, then you can use those files from anywhere on your system, without copying them into your working directory. Environment variables are set in different ways for different shells. Here are example settings for

 export LAMMPS_POTENTIALS=/path/to/lammps/potentials

For more information, do read LAMMPS Documentation https://docs.lammps.org/stable/pair_coeff.html

KIM_SimulatorHeaders.h: No such file or directory during compilation of lammps

If you encounter an error such as the one below during compilation for lammps such as written in Compiling LAMMPS-15Jun20 with GNU 6 and OpenMPI 3

After running the command, 

% make g++_openmpi -j 16

you may encounter

In file included from ../style_pair.h:112:0,
                 from ../force.cpp:20:
../pair_kim.h:70:34: fatal error: KIM_SimulatorHeaders.h: No such file or directory
 #include "KIM_SimulatorHeaders.h"

This is due to one of the a header file not found at /usr/local/lammps-29Oct20/src/pair_kim.h. At line 70, modify the actual location of KIM_SimulatorHeaders.h 

/* #include "KIM_SimulatorHeaders.h" */
#include "/usr/local/lammps-29Oct20/lib/kim/kim-api-2.1.3/build/installed-kim-api-2.1.3/include/kim-api/KIM_SimulatorHeaders.h"

Again, after running the command, 

% make g++_openmpi -j 16

you may encounter

mpicxx -g -O3  -DLAMMPS_GZIP -I../../lib/colvars -DLMP_USER_OMP -I../../lib/voronoi/includelink -DLMP_PYTHON -I../../lib/poems -DLMP_MPIIO -I../../lib/message/cslib/src -I../../lib/latte/includelink -DLMP_KOKKOS  -DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX=1     -I/usr/include/python2.7 -I/usr/include/python2.7   -I./ -I../../lib/kokkos/core/src -I../../lib/kokkos/containers/src -I../../lib/kokkos/algorithms/src --std=c++11 -fopenmp -I./ -I../../lib/kokkos/core/src -I../../lib/kokkos/containers/src -I../../lib/kokkos/algorithms/src   -DLMP_KIM_CURL   -c ../kim_param.cpp
../kim_param.cpp:73:34: fatal error: KIM_SimulatorHeaders.h: No such file or directory
 #include "KIM_SimulatorHeaders.h"

This is due to one of the a header file not found at /usr/local/lammps-29Oct20/src/kim_param.cpp. At line 73, modify the actual location of KIM_SimulatorHeaders.h 

/* #include "KIM_SimulatorHeaders.h" */
#include "/usr/local/lammps-29Oct20/lib/kim/kim-api-2.1.3/build/installed-kim-api-2.1.3/include/kim-api/KIM_SimulatorHeaders.h"

There might be the same issue for kim_init.cpp, fix_store_kim.cpp, pair.kim.h etc

voro++.hh: No such file or directory during compilation of lammps with voronoi

If you encounter an error such as the one below during compilation for lammps such as written in Compiling LAMMPS-15Jun20 with GNU 6 and OpenMPI 3 

../compute_voronoi_atom.h:24:21: fatal error: voro++.hh: No such file or directory

This is due to one of the a header file not found at /usr/local/lammps-29Oct20/src/compute_voronoi_atom.cpp. To resolve the issue, do take a look at Line 23 or 24 and edit to the path where you place voro++.hh

/* #include <voro++.hh> */
#include "/usr/local/lammps-29Oct20/lib/voronoi/voro++-0.4.6/src/voro++.hh"
