Ifort-Stack-Overflow

Fortran Source code, comparable to CROCO-NH (https://github.com/ducousso/CROCO-NH), which generates a "stack-overflow" with intel fortran compiler on linux platform where default stack memory is set to 8192 kbytes.

In general, ALLOCATABLE arrays are more efficient. But in Fortran 90/95 POINTER arrays were more flexible. For example, it was not possible to use ALLOCATABLE arrays as components of derived types. Fortran 2003 fixed that issue. So use ALLOCATABLE arrays when you can.

To select stack overflow or not

Edit the file stack_overflow.f90 and activate call sub_calc_stack_overflow(nlevs) or call sub_calc_no_stack_overflow(nlevs)

To compile

./compile.sh

To execute

./stack_overflow

To clean directory to intermediate files

./clean.sh

Memory profiling using Valgrind

 valgrind --tool=massif --stacks=yes --max-stackframe=8652800 ./stack_overflow
