Solved: IMSL to MKL

elquin · ‎03-14-2012

I'm changing the huge system code with MKL which was work with IMSL.

The default real kind of the code is set to 8 (/real_size:64).

I used double precision MKL functions like

PROGRAM ...

IMPLICIT NONE

REAL A, B, ...

CALL DGEEV(A,B,...)

END PROGRAM

When compiled first with MKL library, almost 1,000 warnings (warning #6738: The type/rank/keyword signature for this specific procedure matches another specific procedure that shares the same generic name.) show up but it disappears when compiled again.

I wonder this warning signs affect the code results.

best regards,

You should expect such problems to arise whenever you try to combine some of routines compiled with /real_size:64 with other routines (your own, or in libraries such as MKL) which were compiled with, in effect, /real_size:32.

The problem is compounded by you use of the specific subroutine DGEEV rather than the generic subroutine GEEV. If you had called GEEV, the compiler would have produced a call to the correct specific subroutine based on the types of the actual arguments (after they had been promoted because of the /real_size:64 option).
