[Pw_forum] can not install parallel run of QE

[Yu, Tao]

What of parallel environment is required? like MPI, or something else?


I just want to make sure with that, only serial QE can run. Can we still run QE with 8 cores, not crossing nodes? Or that means I can only run QE with 1 core.

It is explained in some detail in the user guide: "configure" did not detect your parallel environment, for one out 1001 possible reasons

Hi,


During the installation process, after running ./configure, it returned a piece of information,


Parallel environment not detected \(is this a parallel machine?\).\
Configured for compilation of serial executables.


What happened there? Does this mean I can only run with 1CPU? How to fix that?


Many thanks,


Tao
