Hello all.
I am running a interface tension calculation of an ionic liquid and water with MPI on lammps (31 March 2017) in the nvt build. The package works fine with every other simulation however this one generates the following problem:
LAMMPS (31 Mar 2017)
Reading data file …
ERROR on proc 0: Cannot open file data.BMIMBrC1 (…/read_data.cpp:1876)
Hello all.
I am running a interface tension calculation of an ionic liquid and water
with MPI on lammps (31 March 2017) in the nvt build. The package works fine
with every other simulation however this one generates the following
problem:LAMMPS (31 Mar 2017)
Reading data file ...
ERROR on proc 0: Cannot open file data.BMIMBrC1 (../read_data.cpp:1876)
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------We had run this in two different machines with different OS distros (Arch
and Mint) both with the same compilers and lammps versions.
yes, but are the files all there, too? and with the exact same name?
also double check your input file, sometimes typos happen because of
people typing into the wrong window and don't notice when saving.
to test the 31 Mar 2017 executable, please try out some of the inputs
in the examples folder that use data files.
it is *extremely* unlikely these days, that there is a released LAMMPS
version with a defect that would inhibit reading a (correct and
present) data file, since the distribution is subject to significant
regression testing and reading all kinds of data files in different
styles is part of the test suite.
