source: palm/trunk/SOURCE/restart_data_mpi_io_mod.f90 @ 4561

Last change on this file since 4561 was 4539, checked in by raasch, 5 years ago
checks added, if index limits in header are exceeded (restart_data_mpi_io_mod), bugfix in rrd_mpi_io_int_2d, location and log_point names added/modified, cpu time per grid point and timestep does not included initialization and spinup any more (cpulog_mod)

	2045	!-- In my understanding is it standard conform to pass the second dimension to a 1d-
	2046	!-- array inside a subroutine and the compiler is responsible to generate code for
	2047	!-- copying. Acually this works fine for INTENT(IN) variables (wrd_mpi_io_surface_2d).
	2048	!-- For INTENT(OUT) like in this case the code works on pgi compiler. But both, the Intel 16
