[molpro-user] problem in requesting multiprocessor job and intermediate file size

[Andy May]

Xueliang,

The error:

'unknown option -n'

comes from the main molpro.exe. The main executable should never be 
given the '-n' option. In the bin directory you should see:

molpro
molpro.exe

The 'molpro' file is the shell script which can parse '-n' option and 
then launch molpro.exe in parallel. Can you ensure that the shell script 
is being called, not the executable? If this does not solve the problem, 
please run with '-v' option and send the terminal output.

Best wishes,

Andy
