квантовый эспрессо получает ошибку mpirun

я занимаюсь расчетом фононов в квантовом эспрессо. при этом я получаю ошибку типа..

      **********-ideapad:gr$ mpirun ph.x <sample.ph.in> sample.ph.out

Note: The following floating-point exceptions are signalling: IEEE_DENORMAL
STOP 1
--------------------------------------------------------------------------
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: [[3530,1],1]
  Exit code:    1
--------------------------------------------------------------------------

Кто-нибудь может мне с этим помочь.

спасибо, крк.
