LAPACK compilation “error : no target found”

LAPACK compilation “error : no target found”



EDIT: Grab a new copy of pwscf and retry this error may not reappear. I recently encountered this on a system containing intel cpu ( it is not a problem of cpu, but of a compiler).  I tried to compile with fresh package and found to be working fine.

During pwscf compilation, rarely we can encounter this kind of error. I have witnessed this error two times with Intel CPU and ubuntu 14.04 with nvidia graphic cards. This error may arise due to compiler problems, adding compiler option in the make.inc file solves the problem.
make.inc file is present in espresso-5.1/lapack-3.2/

in the make.inc file you will see like the following

#
FORTRAN     = gfortran
OPTS             = -O3 -g
DRVOPTS     = -O3 -g
NOOPT          = -O0 -g
LOADER       = mpif90
LOADOPTS  = -g -pthread
#


Change it to as follows

.
#
FORTRAN = gfortran
OPTS = -shared -O2 -fPIC
DRVOPTS = $(OPTS)
NOOPT = -O0 -frecursive -fPIC
LOADER = mpif90
LOADOPTS = -g -pthread
#

:
#
#
CC is the C compiler, normally invoked with options CFLAGS.
#
CC = gcc
CFLAGS = -O3

exit vi and type make ..
after compilation of LAPACK continue the espresso compilation (without cleaning previous compilation)


The compilation was successful with above modification.

Easy and efficient way of creating surface/slabs for pwscf/quantum espresso

Easy and efficient way of creating surface/slabs for pwscf/quantum espresso There are a few ways of creating surfaces for pwscf/quantum espresso input files. It is easy to write coordinates for surface manually, provided you know crystallography. Writing unusual surfaces may be difficult. Hence there one easy way of creating surfaces for beginners. Atomic Simulation Environment (ASE) is a toolbox consisting of several tools and python modules can be used for setting up, manipulating, running, visualizing and analyzing atomistic simulations. First of all we need to set up ASE environment, the code is freely available under the GNU LGPL license . Install the ASE as mentioned in the ASE home page and run all the tests. To create CuZn alloy 211 surface I will use https://wiki.fysik.dtu.dk/ase/ase/surface.html?highlight=surface#ase.lattice.surface web-page as a reference and you can find more details for creating various surfaces there. And here I will only emphasis on ex...

Running pwscf/Quantum ESPRESSO on Beowulf like clusters

Running pwscf/Quantum ESPRESSO on Beowulf like clusters This post may be helpful for beginners for using pwscf/ quantum espresso on Beowulf like Linux clusters. This post assumes that you have already built or have an access to it. In case you want to build it one, click here, but this need some changes and some tricks involved, which I will be posting next. To successfully run pwscf/ quantum espresso on cluster we need to follow new steps 1) Installing necessary libraries and openmpi 2) Installing pwscf/ quantum espresso 3) configuring ssh for mpi to access other nodes without password 4) Putting pseudo potential file on all nodes 5) executing the pwscf/ quantum espresso for calculation From here we will take one by one Step 1) Installing necessary libraries and openmpi I have used Ubuntu hence I will use apt-get for installing form terminal, if you have other distribution you can follow as recommended. sudo apt-get install openmpi-bin openmpi-common libopenmpi1.6 ...

Q. How to create input file from cif files? Ans. First of all, why cif files to be used to create input file for QE. Because bigger unit cells with more than 3 types atoms are difficult to write by hand and to verify the input (at least for me). Cif files consists of everything related to crystallography of the material of the interest but it is not yet ready for the in put for QE. Lets take an example how to prepare input from cif file called EDI.cif (available from IZA website) Step 1. copy the EDI.cif to ~(path to espresso)/espresso-xx.x/PW/tools Step 2. type "./cif2qe.sh EDI > EDI.in" by typing this you will be invocking a script to convert cif files to QE input file (dont add cif extenction for EDI in put and give .in extenction for out put) Step 3. You should see EDI.in QE input file in the folder and open this file, you can observe that the scpipt had printed many option for you which is required for QE calculation but this is not complete an exhausti...
