Compiling Quantum Espresso

http://www.quantum-espresso.org/

Suggested

Standard Proteus nodes

• intel/composerxe/2015.1.133
• proteus-openmpi/intel/2015/1.8.1-mlnx-ofed

New Proteus (Intel Sky Lake) nodes

• intel/composerxe/2019u1
• proteus-openmpi/intel/2019/3.1.4

Compilation Options

• -O3 -xHost
• use MKL; see Compiling for Intel with Intel Composer XE, MKL, and Intel MPI#MKL Link Line Advisor
  • if the authors of the code you are compiling have set up the makefiles or build scripts properly, you should not have to set the MKL-related options

Running

• Use fixed16 or fixed40 PEs

OBSOLETE

Download

Individually from http://www.qe-forge.org/gf/project/q-e/frs/?action=FrsReleaseBrowse&frs_package_id=18

    [juser@proteusi01 ~]$ mkdir src
    [juser@proteusi01 ~]$ cd src
    [juser@proteusi01 src]$ wget ....../espresso-X.Y.tar.gz
    [juser@proteusi01 src]$ tar xf espresso-X.Y.tar.gz

Configure

    [juser@proteusa01 espress-X.Y]$ ./configure --prefix=$HOME/espresso --enable-parallel --enable-openmp --enable-shared --with-scalapack=intel | tee Configure.out

Check the file Configure.out to see that all the appropriate libraries were picked up:

    The following libraries have been found:
      BLAS_LIBS=  -lmkl_gf_lp64  -lmkl_gnu_thread -lmkl_core
      LAPACK_LIBS=
      SCALAPACK_LIBS=-lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64
      FFT_LIBS=-lfftw3xf_intel
      ...
      Parallel environment detected successfully.\
      Configured for compilation of parallel executables.

Modify make.sys

    CFLAGS         = -O3 -xAVX -ipo  $(DFLAGS) $(IFLAGS)
    ...
    FFLAGS         = -O3 -xAVX -ipo -assume byterecl -g -traceback -par-report0 -vec-report0 -openmp
    ...
    AR             = xiar

Build

    [juser@proteusi01 espresso-X.Y]$ make -j 16 pw | tee Make.pw.out

Running

Since this uses Intel MPI, the intelmpi parallel environment (PE) must be requested in the job script, e.g.

    #$ -pe intelmpi 128
    ...
    ### "-rmk sge" specifies Grid Engine integration
    ### -np not necessary singe GE integration allows pw.x to read number of slots from the environment
    mpirun -rmk sge pw.x ...
