Function/Subroutine Documentation

abort_mpi()

integer function, public mpi_ops::abort_mpi

Abort MPI suddenly.

Returns

ierr

Definition at line 227 of file MPI_ops.f90.

Here is the caller graph for this function:

broadcast_input_opts()

integer function, public mpi_ops::broadcast_input_opts

Broadcasts options (e.g. user-prescribed) that are not passed through the HDF5 output file (i.e. ltest, no_plots, ...).

See also

read_input_opts()

Note

Some variables (e.g. eq_style, ...) are not passed over MPI. Every process should call its own reconstruct_pb3d_in() in order to obtain them.

Returns

ierr

Definition at line 247 of file MPI_ops.f90.

sudden_stop()

subroutine, public mpi_ops::sudden_stop

(

integer, intent(in)
