[lammps-users] MPI_INIT failed

Hello,

When I tried MPI run, I got an error message below:

Error obtaining unique transport key from ORTE (orte_precondition_transports not present in
the environment).

PML add procs failed
–> Returned “Error” (-1) instead of “Success” (0)

Could anyone let me know what is the problem??

Thank you.

that is certainly an MPI issue and not something related to LAMMPS.
this is also usually machine/installation specific. you either didn't
run your job the way it is supposed to be done or something is
amiss on that machine.

i would contact your help desk or the system admin/manager
f the machine that you are using.
