  • Thread-topic: [ptp-user] debug code in Eclipse with MPI support
Hi  Greg

I am using a open-source software with its own cmake file. I have enabled the debug mode using that cmake file when I built the project. I have added some my own code to the open-source software, but the new added part makes the software can only run in serial. When I tried to run it with MPI in parallel, it gave me a Segmentation fault. That is why I have to debug. And I have set the break point before the place where Segmentation fault occurs, but I do not know why I can not debug it.

Thanks for your help.

Best wishes

Hi Fan Li,

Have you compiled the application with debugging enabled (i.e. with -g)?

Regards,
Greg

Dear users

I am using the "eclipse for scientific computing" and want to debug a programme with MPI support.

The programme can run in terminal with mpi in this way

mpirun -np 4 gmx_mpi mdrun -s diff.tpr -c diff.gro -ntomp 1

Accordingly, I set the debug configure as below

After I start debugging, there is no out put from the console and no variable values are displayed. 

The below screen shot after debugging

Could you tell me what is wrong?
