Hi Carlos,

I guess you are using Ubuntu on Windows App for this?
Then I also guess you copy pasted the control and ctrl files from the Windows system to the Ubuntu home folder using the Windows explorer.

This will cause the files to have no permissions and therefore "not exist" in the Ubuntu universe.

You can check this by opening the Ubuntu App and navigating to the location of the files (in the Ubuntu app using the cd command, not the windows explorer) and then type:

Code:

ll

You will see a list of permissions next to the files in the folder.
Control.txt and ctrl.txt probably have just ------ next to them.

You can give these files read and write permissions using:

Code:

chmod u+rw control.txt

Code:

chmod u+rw ctrl.txt

This will provide the user (you) the read (r) and write (w) access and therefore programs you initiate can also read and write to these files.

This should sort your issue

Hi kamath,

you are amazing. It's working. Thank you a lot!

I already have another question.

when I was doing the installation I wrote "make all -j 4" but my pc has 6 core. How I can change this?

Thank you

Thanks

If you have 6 physical cores, you can use

make -j 12

but for mpirun only -n 6
