Dear all,
I am wondering about alignment of allocatable arrays: Does the gfortran
compiler in its latest version automatically align arrays to the 64 byte
boundary? For comparison, the Intel compiler has a flag "-align
array64byte", which forces alignment of all arrays (except for the ones
in COMMON). I did not find something similar in the gfortran documentation.
Background of my question: I would like to use statements like
"!$OMP SIMD ALIGNED(foobar:64)"
in my code, however, this is only appropriate if the compiler indeed
alignes arrays.
Thank you!
Best regards from Munich
Tobias
