Reference Number : DPD200192258


Version : versions 10.2 Update 6 and 10.3 beta


Product : Intel(R) MKL


Operating System : all supported by Intel(R) MKL at this moment


Problem Description :

The F90 DSS interface is broken because of currently DSS API supports Double Precision data types only.
Compilation DSS interfaces with Single Precision Data types will produces something like the following compilation errors

dss_sym_f90.f90(78): error #6633: The type of the actual argument differs from the type of the dummy argument. [VALUES]
dss_sym_f90.f90(82): error #6633: The type of the actual argument differs from the type of the dummy argument.
[RHS]
dss_sym_f90.f90(82): error #6633: The type of the actual argument differs from the type of the dummy argument. [SOLUTION]
dss_sym_f90.f90(89): error #6633: The type of the actual argument differs from the type of the dummy argument. [STATOUT]

Workaround:

As a temporarily workaround, we would recommend you to do the following:
1) make the call call DSS_CREATE( handle, MKL_DSS_SINGLE_PRECISION)
and then
2) manually change the API of these functions ( mkl_dss.f90 which is located in <mklroot\include> firectory ) by replacing REAL(KIND=8) by REAL(KIND=4) into those routines, which have been used into your application.

As an example, please see the MKL Forum tread, where the similar problem has been discussed.

Resolution Status :
fixed the next Update - 10.2 Update 7 and 10.3 Update 1
