Introduction

/apps/espresso/3.2.2/

From the PWscf Website:

PWscf can currently perform the following kinds of calculations:

  • ground-state energy and one-electron (Kohn-Sham) orbitals
  • atomic forces, stresses, and structural optimization
  • molecular dynamics on the ground-state Born-Oppenheimer surface, also with variable-cell
  • Nudged Elastic Band (NEB) and Fourier String Method Dynamics (SMD) for energy barriers and reaction paths
  • phonon frequencies and eigenvectors at a generic wave vector, using Density-Functional Perturbation Theory
  • effective charges and dielectric tensors
  • electron-phonon interaction coefficients for metals
  • interatomic force constants in real space
  • third-order anharmonic phonon lifetimes
  • Infrared and Raman (nonresonant) cross section
  • macroscopic polarization via Berry Phase

Sample make.sys file

The Espresso 4.0.4 make.sys file below results in a successful build using the following libraries and compilers.

  1. FFTW (3.1.2)
  2. Goto BLAS (1.26, penrynp)
  3. LAPack (MKL 10.0.2.018)
  4. Intel Compiler Suite (10.1.015)
  5. MVAPICH (0.99)
