i am trying to run this example in palabos and i keep getting this problem on the terminal each time i try to run the executable file.
this is the message i keep getting on the terminal:
Error the parameters are wrong. The structure must be :
1 : N

Primary job terminated normally, but 1 process returned
a non-zero exit code… Per user-direction, the job has been aborted.


mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[44811,1],1]
Exit code: 1

there is a missing parameter when running your code. you should run it like:

mpirun -np 4 ./your_code 10
