Compiling Quantum ESPRESSO-6.5.0 with Intel MPI 2018 on CentOS 7

Step 1: Download Quantum ESPRESSO 6.5.0 from Quantum ESPRESSO Download Site or git-clone QE

% git clone

Step 2: Remember to source the Intel Compilers and indicate MKLROOT in your .bashrc

export MKLROOT=/usr/local/intel_2018/mkl/lib
source /usr/local/intel/2018u3/parallel_studio_xe_2018/bin/ intel64
source /usr/local/intel/2018u3/compilers_and_libraries/linux/bin/ intel64
source /usr/local/intel/2018u3/impi/2018.3.222/bin64/ intel64

Step 3: Make a file call and copy the contents inside.

export F90=mpiifort
export F77=mpiifort
export MPIF90=mpiifort
export CC=mpiicc
export CPP="icc -E"
export AR=xiar
export BLAS_LIBS=""
export LAPACK_LIBS="-lmkl_blacs_intelmpi_lp64"
export SCALAPACK_LIBS="-lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64"
export FFT_LIBS="-L$MKLROOT/intel64"
./configure --enable-parallel --enable-openmp --enable-shared --with-scalapack=intel --prefix=/usr/local/espresso-6.5.0
% ./
% make all -j 16 
% make install

Checking of availabilities of Libraries

% ./configure --prefix=/usr/local/espresso-6.5.0 --enable-parallel --enable-openmp --enable-shared --with-scalapack=intel | tee Configure.out

Checking Configure.Out, there are some missing libraries which you have to fix.


ESPRESSO can take advantage of several optimized numerical libraries
(essl, fftw, mkl...). This configure script attempts to find them,
but may fail if they have been installed in non-standard locations.
If a required library is not found, the local copy will be compiled.

The following libraries have been found:
BLAS_LIBS= -lblas
LAPACK_LIBS=-L/usr/local/lib -llapack -lblas

Intel MPI Parameter to consider for Performance

Selection of best available communication fabrics

Suggestion 1:

 sock tcp  TCP/IP-enable network fabrics, such as Ethernet and Infiniband* (through IPoIB*)
 shm shm Shared-memory only
 ssm  shm:tcp  Shared-memory + TCP/IP
 rdma dapl  DAPL-capable network fabrics, such as Infiniband*, iWarp*, Dolphon*, and XPMEM* (through DAPK*)
 rdssm shm:dapl  Shared-Memory + DAPL + sockers
 ofa  OFA-capable network fabrics including Infiniband* (through OFED* verbs)
 tmi  TMI-capable network fabrics including Qlogic*, Myrinet* (through Tag Matching Interface)


Suggestion 2:

I_MPI_DAPL_UD Values Description
  • Connectionless feature works for DAPL fabrics only.
  • Works with OFED 1.4.2 and 2.0.24 or higher
  • Provides better scalability
  • Significant reduces memory requirements


Suggestion 3:

 I_MPI_PERHOST Values Remarks
 1  Make round-robin distirbution (Default value)
 all  Maps processes to all logical CPUs on a node
 allcores  Maps processes to all physical CPUs on a node


Suggestion 4:

I_MPI_SHM_BYPASS Values Remarks
 disable Set I_MPI_SHM_BYPASS* to ‘enable’ to turn on RDMA data exchange within single node that may outperform regular shared memory exchange. This is normally happens for large (350kb+) messages.


Suggestion 5:

 recursive doubling algorithm 1
 Rabenseifner’s algorithm 2
 Reduce + Bcast 3
Topology aware Reduce + Bcast algorithm 4  
 Binomial gather + scatter algorithm 5
 Topology Aware Binomial Gather + scatter algorithm 6
 Ring Algorithm 7


Suggesion 6:

I_MPI_WAIT_MODE Values Remarks
 1 Set I_MPI_WAIT_MODE ‘to enable’ to try wait mode of the progress engine. The processes that waits for receiving that waits for receiving messages without polling of the fabrics(d) can save CPU time.

Apply wait mode to oversubscribe jobs

Compiling with NWChem-6.6 with Intel MPI-5.0.3

Here is a write-up of my computing platform and applications:

  1. NWChem 6.6 (Oct 2015)
  2. Intel Compilers 2015 XE (version 15.0.6)
  3. Intel MPI (5.0.3)
  4. Intel MKL (11.2.4)
  5. Infiniband Inteconnect (OFED 1.5.3)
  6. CentOS 6.3 (x86_64)

Step 1: First thing first, source the intel components setting from

source /usr/local/intel_2015/parallel_studio_xe_2015/bin/ intel64
source /usr/local/intel_2015/impi/ intel64
source /usr/local/intel_2015/composerxe/bin/ intel64
source /usr/local/intel_2015/mkl/bin/ intel64

Step 2: Assuming you are done, you may want to download the NWChem 6.6 from NWChem Website. You may also want to take a look at instruction set for Compiling NWChem.

I have less problem running NWCHEM when the installation and the compiling directories are the same. If you recompile, do untar from source. Somehow the “make clean” does not clean the directories properly.

# tar -zxvf Nwchem-6.6.revision27746-src.2015-10-20.tar.gz
# cd nwchem-6.6

Step 3: Apply All the Patches for the 27746 revision of NWChem 6.6

gzip -d Xccvs98.patch.gz
patch -p0 < Xccvs98.patch

General Site Installation

Determine the local storage path for the install files. (e.g., /usr/local/NWChem).
Make directories

# mkdir /usr/local/nwchem-6.6
# mkdir /usr/local/nwchem-6.6/bin
# mkdir /usr/local/nwchem-6.6/data

Copy binary

# cp $NWCHEM_TOP/bin/ /usr/local/nwchem-6.6/bin
# cd /usr/local/nwchem-6.6/bin
# chmod 755 nwchem

Copy libraries

# cd $NWCHEM_TOP/src/basis
# cp -r libraries /usr/local/nwchem-6.6/data

# cd $NWCHEM_TOP/src/
# cp -r data /usr/local/nwchem-6.6

# cd $NWCHEM_TOP/src/nwpw
# cp -r libraryps /usr/local/nwchem-6.6/data

The Final Lap (From Compiling NWChem)

Each user will need a .nwchemrc file to point to these default data files. A global one could be put in /usr/local/nwchem-6.6/data and a symbolic link made in each users $HOME directory is probably the best plan for new installs. Users would have to issue the following command prior to using NWChem: ln -s /usr/local/nwchem-6.6/data/default.nwchemrc $HOME/.nwchemrc

Contents of the default.nwchemrc file based on the above information should be:

nwchem_basis_library /usr/local/nwchem-6.6/data/libraries/
nwchem_nwpw_library /usr/local/nwchem-6.6/data/libraryps/

Compiling VASP-5.2.12 with Intel MPI-5.0.3

Vienna Ab initio Simulation Package (VASP) is a computer program for atomic scale materials modelling, e.g. electronic structure calculations and quantum-mechanical molecular dynamics, from first principles.

A. Prerequisites

To Compile VASP-5.2.12, I used

  1. Intel Compiler 15.0.6
  2. Intel MPI 5.0.3
  3. Maths Kernel Library 11.2.4

B. Compiling VASP Libraries

Assuming you have unpacked the VASP files. Here is may make file

C. Compiling VASP

1. Copy the Makefile from makefile.linux_ifc_P4 in the vasp software.

# cp makefile.linux_ifc_P4 Makefile

2. Edit the Makefile

# fortran compiler and linker
# fortran linker

The -xCORE-AVX2 is for Haswell Architecture


BLAS= -mkl=cluster

-mkl=cluster is an Intel compiler flag that to include Intel MKL libraries, that will link with Intel MKL BLAS, LAPACK, FFT, ScaLAPACK functions that are used in VASP.


fftmpiw.o fftmpi_map.o fftw3d.o fft3dlib.o
INCS = -I$(MKLROOT)/include/fftw



Since the -mkl=cluster, includes MKL ScaLAPACK libraries also, it is not required to mentioned the ScaLAPACK libs. That include LAPACK

Compiling CPMD-3.17.1 with Intel- and iMPI-14.0.2

To get the source code from CPMD, please go to

Step 1: From the CPMD Directory

$ tar -zxvf cpmd-v3_17_1.tar.gz
$ cd ~/CPMD-3.17.1/CONFIGURE
$ ./ IFORT-AMD64-MPI > Makefile

Step 2: Prepare the initialization

source /usr/local/intel_2013sp1/composerxe/mkl/bin/ intel64
source /usr/local/intel_2013sp1/composerxe/bin/ intel64
source /usr/local/intel_2013sp1/impi/ intel64
source /usr/local/intel_2013sp1/composerxe/tbb/bin/ intel64
source /usr/local/intel_2013sp1/itac/

Step 3:  I’m using MKL for the Mathematical Libraries

#--------------- Default Configuration for IFORT-AMD64-MPI ---------------
SRC  = .
DEST = .
BIN  = .
MKLPATH = /usr/local/intel_2013sp1/mkl/lib/intel64

Step 4: Compile CPMD

$ make

If the compilation succeed, it should generate a cpmd.x executable.

Step 5: Pathing
Make sure your $PATH reflect the path of the executable cpmd.x. It is also important to ensure that you check that the libraries are properly linked to the executable

# ldd cpmd.x
