How do I link oneMKL with Visual Studio 2019

[Nikhil_T]

I have started to used oneMKL in VS 2019. I changed the setting in solution properties of  Use oneMKL to Parallel. However when I #include "mkl_sycl.hpp", it says cannot open source file "mkl_sycl.hpp".

Hi,

Kindly specify your oneAPI toolkit version, OS, and VS19 version. Please note that some of the header files have been moved (to a different directory) or renamed in the latest oneAPI release.

Give it a try with the latest MKL code samples located under:

oneAPI_root/mkl/latest/examples/examples_sycl.zip

You may rely on the Intel MKL link line advisor tool to check what all libraries are recommended for your application:

How do I use the link line? Is it for the CLI execution?

Also, how do I use the oneMKL in parallel mode in VS 2019?  My Version for VS 2019 is 16.8.3.

Hi,

To set MKL mode to parallel:

• Open the property pages of your project.
• Select Intel libraries for oneAPI on the left column and double click on use oneMKL under the Intel oneMKL tab to change the MKL mode to parallel/sequential/cluster.

oneMKL may also require additional library dependencies for your application to run. Kindly include these additional dependencies as suggested by the link line advisor tool.

To include additional dependencies:

• Open the property pages of your project.
• Select the Linker tab on your left column and click on Input.
• Type in the additional dependency libraries. (mkl_core_dll.lib, mkl_tbb_thread_dll.lib)

Thanks,

Rahul

Hello @RahulV_intel 

I am trying to link oneMKL using the above mentioned process. Also trying to include the additional libraries. However, while building, the process seems to get stuck and does not compile. 

I am using oneAPI 2021.1.0 and VS 2019.

Even when I use a simple "hello world" code and try to link oneMKL (even though there is no use of MKL in the code), the simple hello world code does not compile. The same code however compiles and prints hello world when i set use mkl  to no. 

Also, while compiling, the task manager shows SYCL post link tool using almost the whole CPU.

Any suggestions?

Hi @Nikhil_T,

The issue has been fixed in the latest release of oneAPI 2021.2. Could you try it out with the latest version and let us know if you face any issues?

and the one as :

I have set use MKL to Parallel mode. and rest settings as default. I am now using oneapi 2021.2.0 and VS 2019. Still getting the errors
