Quantum Espresso is a software for electronic-structure calculations and materials modeling at the nanoscale. The installation of Quantum Espresso is quite easy because it includes external libraries which it needs. But we are encouraged to install Quantum Espresso using our own machine optimized external libraries such as Basic Linear Algebra Subprograms (BLAS), Linear Algebra Package (LAPACK), Scalable LAPACK (SCALAPACK), and Fastest Fourier Transform in the West (FFTW). ###External Libraries There are several repositories or development teams which provide external libraries. For example is Netlib which provides BLAS, LAPACK, and SCALAPACK. But, for machines with Intel processor, maybe the best external libraries out there is Intel® Math Kernel Library which has a non-commercial version as standalone or included in Intel® Parallel Studio XE 2013 for Linux that can be downloaded in Intel Non-Commercial Software Development. Intel® Math Kernel Library provides BLAS, LAPACK, SCALAPACK, and even FFTW interfaces. ###Getting Started My test machine is Supermicro X9DRD-7LN4F which has Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz with 8 cores and 16 threads and 64 GB RAM. For compilers I will be using Intel compilers which is included in Intel® Parallel Studio XE 2013 for Linux and OpenMPI for parallelization. ####Installing Intel® Parallel Studio XE 2013 for Linux
