Hello everyone I have a problem while using ORCA software on windows, when I determine the number of processors my job (any jobs) fails ?

I share the dialogue of my error here:

ERROR (ORCA_MAIN): For parallel runs !!!

!!! ORCA has to be called with full pathname !!!

[file orca_tools/qcsys.cpp, line 50]:

Thanks!

Hello, Romina Chegini

You need to give the full path to the executable to run ORCA in parallel.

It might be something like "C:\orca\orca.exe".

So the command will be "C:\orca\orca.exe sample.inp"

Have a look at this online manual: https://www.faccts.de/docs/orca/6.0/tutorials/first_steps/parallel.html

Regards,

Dilawar
