Hello

First of all, it seems you're having lots of input reads. So this is going to take a while. However, the most important problem is as follows:

  0:00:00.001     1M / 17M   INFO    General                 (main.cpp                  :  78)   Maximum # of threads to use (adjusted due to OMP capabilities): 1

It seems that your cluster imposes some additional restrictions on jobs that use OpenMP. You'd likely need to check with your system administrator how to setup # of OpenMP threads during your job submission
