Re^9: Firefly-8.0.1 is not running on system with Intel MPI-4.1.X...

Siddheshwar Chopra

Dear Pavel Sir,
I am using the appropriate Intel MPI version of firefly.. But it is 4.1.024 one.. I really doubt that there is any issue with the configuring Sir. I am also using the absolute paths everywhere and with proper file permissions... But the same error returns:: "Unable to open input file"..
I am actually upset with this error. By common sense it feels like Firefly is facing file permission or file locating issues... Please throw more light on this error. If there was an error associated to libraries etc., shouldn't it have shown "unable to use shared libraries etc"?? But why does it tell me "unable to  open input file"?

Alex Sir I am really missing a manual for Firefly which consists of TILL NOW obtained errors and their tried and tested solutions.. It would be really great to compile such a manual.

Please help Sir.

I am running "qff2 firefly.conf" now, but it is again and again asking me the details which were already provided to create firefly.conf. What I have to do next Sir?

NBO license information,f if you have it. If you want to use more then one CPU make sure appropriate MPI libraries is installed together with mpirun/mpiexec. In your case IntelMPI.
