MKL ERROR: Parameter 2 was incorrect on entry to vdRngUniform

xiaomingg — Sat, 24 Mar 2012 01:26:01 GMT

Hi,

I try to change a fortran 77 program using IMSL to a fortran 90 program using MKL. I got the error message:

MKL ERROR: Parameter 2 was incorrect on entry to vdRngUniform.

I don't know what does it mean. How to fix the problem. Thank you.

Sherry

My program looks like this:

Why did you make the TYPE and other declarations inoperative in your subroutine by making them comment lines, causing STREAM to become REAL, etc., because of the implicit typing?

Quoting mecej4

Why did you make the TYPE and other declarations inoperative in your subroutine by making them comment lines, causing STREAM to become REAL, etc., because of the implicit typing?

If I don't comment them out, I get error message when I compile.

why don't you use the existing examples? see - \examples\vslf\sources\vdrnguniform.f.

Killing the messenger does not prevent bad things from happening. By relying incorrectly on implicit typing, you promoted the compile time errors to run time aborts.

Yes, I try to follow the example. The example has everything in one program. My program has a few subroutines. I have to sample uniform, binomial, normal in my subroutine.

Yes, you are absolutely right.

I use IMPLICIT NONE now, but I still get the following compile time errors. I don't know what the error messages mean.

Can anyone please help? Thank you very much.

If you have have both the f77 vsl include file and the f90 USE, as you showed at the top, that may account for the error.

Hello Sherry,

I developed a short test case that demonstrates use of Intel MKL generators in the application that does random number generation inthe subroutine. I tried to reproduce your code as much as possible. The test case, whichis built using Intel Fortran compiler, runs and printsrandom numbers obtained as result of call to Intel MKL Uniform RNG. Please, let me know if this helps to resolve the compilation and runissues on your side.

Thanks,
Andrey

Hi Andrey,

Thank you for your example. It works fine. I guess I need the interface block in my code. If I have main program calls subroutine A, and subroutine A calls subroutine B. I need interface block in subroutine A before calling subroutine B, am I right?

An interface block is one method for providing a required explicit interface to a routine.

Another method is to declare the called or referenced routines in a module and, in the caller(s), USE that module.

The Fortran reference manual should be consulted regarding circumstances in which an explicit interface is obligatory.

Hi Sherry,

As Mecej4 mentioned in his post,please chooseone of the approaches for the explicit interface specification that would workin your app:either interface statement (as in the example above), ora module based scheme (please, have a look atmkl_vsl.f90 fileas one possible example).

Thanks,
Andrey
