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

Pavlo Solntsev

Dear Siddheshwar.

Could you please give EXACT command you used to start FF. Step-by-step. How you created running script and how you executed it. Also, i would be glad to see the script too. Make sure all private information is removed from the script.

From the error file you sent, i found mistake in you path to the input and output files.

+ /usr/bin/time mpirun -np 1 /home/schopra/ff801intel/firefly801 -ex /home/schopra/ff801intel -i /home/schopra//home/schopra/ff801intel/INPUT/Si26H26.inp -o /home/schopra//home/schopra/ff801intel/INPUT/Si26H26.out -t /home/schopra/ff801intel/tmp/13216/

Once again, the script should be executed as :

qff2 inputfilename

Do not provide full path. For example, i have file H2.inp in some folder "dir1". I need:
$ cd dir1
$ qff2 h2.inp
$ bash
$ qsub h2.pbs

Also, why do you use IntelMPI for one CPU? To debug IntelMPI, i would recommend you to use at least two CPUs.

Do you use PBS?

What exact file did you execute to get *.e and *.o files?

Please, answer all my questions. As soon as i get all this information it will be easy to go forward.

>Dear Sir,
>I followed the steps suggested by you regarding running the i/p file using qff2. Sir, I ran the job, and got the two files with extensions ".e" and ".o". Please find attached the ".e" file. I could not get any output file after running qff2 inputfile.inp. Please have a look at the file attached and let me know what is happening. As I understand it, it failed to create .out file.. Should I make it .log? Please elaborate the .e file Sir.

>Could you confirm that it finally read the input file?? Let me know.

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.
