Hi

I try to compile dgemm example from article "Using Intel MKL in your C# program", but its not work.
Result matrix C is Zero matrix.

Then, when i try to start dgemm.exe, its generated exception "System.DLLNotFoundException: Unable to load DLL 'mkl.dll'". But mkl.dll is in folder...

How to solve this problem?

Dmitry,

What platform have you tested? What version of MKL was used?
You set MKLROOT?

Dmitry,

look at the result I 've done:

Win7, 64 bit, version MKL -- 10.2 update5

MKL_C#>nmake em64t MKLROOT="C:\APPS\Intel\MKL\10.2.5"

MKL_C#>dgemm.exe

1 0 0 1

1 0 1 0

I use Win7, 32, Visual Studio 2010, MKL 10.2.4.032.

Maybe, I misunderstand this example. I think that resultig matrix is multiplication of A & B.

But why I get exception when start exe file?

Hello, Dmitry,

Zero matrix is correct result.

The dll,including all dependent dlls, should be 'visible'for the Microsoft .NET CLR.Find(among the C# examples nmake output)the command:

set path=...;%path%

and execute it before start dgemm.exe.

Thanks,
Vladimir
