In order to compile thermo_pw the main Makefile and the files install/makedeps.sh and install/plugins_makefile of QUANTUM ESPRESSO need to be changed. In the thermo_pw directory give the command make join_qe. This command exchanges the files contained in thermo_pw with those of the QUANTUM ESPRESSO package.
Typing make thermo_pw from the main QUANTUM ESPRESSO directory, or make from the thermo_pw directory, produces the executable thermo_pw/src/thermo_pw.x that can be found in the QUANTUM ESPRESSO bin/ directory. A few other tool codes are produced as well and linked in the bin/ directory of QUANTUM ESPRESSO.
thermo_pw has been written on a PC with Linux operating system using the gfortran compiler with openMPI parallelization. It has been run in parallel on a Linux cluster with several hundreds processors. It has been tested with Intel/15.0 + mkl/11.2 + openMPI and with Intel/13.1 + mkl/11.2 + openMPI/1.6.5. Any other combination of computer/operating system has not been tested, but usually thermo_pw runs on the same systems where QUANTUM ESPRESSO runs.
