quantum espresso getting mpirun error

na flag

i am doing phonon calculation in quantum espresso. while doing it i am getting an error like..

**********-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
---------------------------------------------

can anyone help me with this.

thank you, krk.

IEEE_DENORMAL is [(mostly) harmless](https://stackoverflow.com/a/44309751/4440445) and the fact that QE emits it appears to be a known issue e.g. [Quantum ESPRESSO (at least) prints IEEE_DENORMAL and similar floating-point exceptions](https://github.com/marvel-nccr/quantum-mobile/issues/52). That mpirun aborts when any process terminates with non-zero status looks like it may be configurable at least in the case of the OpenMPI implementation (search the man page for MCA parameter "orte_abort_on_non_zero_status")

yes i check it and my pc has 4 cores and after that i run the command "mpirun -np 2 ph.x -nk 1 <sample.ph.in> sample.ph.out" but this also gave me the sam error.

Rather, my suggestion was to try something like `mpirun -mca orte_abort_on_non_zero_status 0 ph.x <sample.ph.in> sample.ph.out`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
