Command Line Output

Command-Line Output of SHEMAT-Suite contains, among other things, information about the parameters that were read in by the program, the memory used, and the iteration step of the solver. How much of this information is displayed depends on the keyword # linfo in the Input File.

Memory

Information about the memory (found around line 100 of the command line output) looks like this:

[I] : memory:     362.763 MByte data

The displayed number of MByte is calculated in the following way: The double precision variable memory is defined in the module forward/mode_genrl.f90. In array allocation routines like forward/alloc_arrays.f90, forward/alloc_data.f90, simul/alloc_simul.f90 the number of entries of each allocated array is added to memory.

In forward/forward_init.f90 memory is manipulated as follows:

memory = memory*8/1024/1024

and written to the command-line output. The 8 is based on the assumption that each entry of an array takes up 8 bytes of memory space (like double-precision reals do). The two divisions by 1024 scale the number to MB.

Finally memory is reduced in deallocation routines, like forward/dealloc_arrays.f90 and simul/read_split_sm.f90.
