            By default most of the compilers take integers ( 'int' for C or C++ / 'INTEGER' for Fortran) as 32-bit length. So most applications need to be linked with LP64 MKL libraries. (https://www.intel.com/content/www/us/en/develop/documentation/onemkl-linux-developer-guide/top/linking-your-application-with-onemkl/linking-in-detail/linking-with-interface-libraries/using-the-ilp64-interface-vs-lp64-interface.html)

            So try linking against LP64 interface and see if it works. Additionally, I would suggest you set MKL_VERBOSE=1 (https://www.intel.com/content/www/us/en/develop/documentation/onemkl-linux-developer-guide/top/managing-output/using-onemkl-verbose-mode.html) and then run your code so that you can see what parameters are passed to the function (as your error message says so).

            You can also refer to the examples which comes with oneMKL.There is a similar example under the mkl directory location in your system as below \oneAPI\mkl\2022.0.2\examples\examples_dpcpp\dpcpp\blas\source with usm_gemm.cpp file name which I presume should help you.

            Using Intel oneAPI MKL to perform sparse matrix with dense vector multiplication
            Asked 2022-Mar-14 at 11:03

            I am developing a program, making heavy use of Armadillo library. I have the 10.8.2 version, linked against Intel oneAPI MKL 2022.0.2. At some point, I need to perform many sparse matrix times dense vector multiplications, both of which are defined using Armadillo structures. I have found this point to be a probable bottleneck, and was being curious if replacing the Armadillo multiplication with "bare bones" sparse CBLAS routines from MKL (mkl_sparse_d_mv) would speed things up. But in order to do so, I need to convert from Armadillo's SpMat to something that MKL understands. As per Armadillo docs, sparse matrices are stored in CSC format, so I have tried mkl_sparse_d_create_csc. My attempt at this is below:

            Yes, the cols_end array is incorrect as pointed out by CJR. They should be indexed as 2,3,4,5. Please see the documentation regarding the parameter to the function mkl_sparse_d_create_csc

            cols_end:

            This array contains col indices, such that cols_end[i] - ind - 1 is the last index of col i in the arrays values and row_indx. ind takes 0 for zero-based indexing and 1 for one-based indexing.

            https://www.intel.com/content/www/us/en/develop/documentation/onemkl-developer-reference-c/top/blas-and-sparse-blas-routines/inspector-executor-sparse-blas-routines/matrix-manipulation-routines/mkl-sparse-create-csc.html

            Change this line

            cols_end[i] = static_cast((--X.end_col(i)).pos());

            to

            cols_end[i] = static_cast((X.end_col(i)).pos());

            Now recompile and run the code. I've tested it and it is showing the correct results. Image with results and compilation command

            I already received a solution on the Intel forum. The problem was that I was using 4-byte integers in the program variables and linking mkl_intel_ilp64.lib when the proper library should be mkl_intel_lp64.lib. You can see the solution here: Solution

            You selected the ilp64 version of MKL. That means that integers, longs and pointers are 64-bit. But you are not using gfortran with 64-bit integers, the default in all compilers I know is 32-bit integers. Either you want a different version of MKL, like lp64, or you want to set up your gfortran to use 64-bit default integers. For the former, select the 32bit-integer interface layer in the Link Advisor.

            Unable to load shared library when running on .NET interactive on Mac

            Error: System.DllNotFoundException: Unable to load shared library 'libmkl_rt.dylib' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable: dlopen(liblibmkl_rt.dylib, 1): image not found

            The code runs as expected if I run it with dotnet run but it doesn't on the interactive notebook. What could be the solution? (ps using .NET 5.0)

            Copying the native libraries into /usr/local/lib solved the problem.

            Conan stores all files and data in ~/.conan. If you are fine with this behavior, you can skip to Conan Profiles section. To change this behavior, set the environment variable CONAN_USER_HOME to a path of your choice. A .conan/ directory will be created in this path and future Conan commands will use this directory to find configuration files and download dependent packages. Packages will be downloaded into $CONAN_USER_HOME/data. To change the "/data" part of this directory, refer to the [storage] section of conan.conf file. To make this setting persistent across terminal sessions, you can add below line to your ~/.bashrc or custom runscript. Refer to Conan Documentation for more details.

            build_functional_tests=[True | False]. Setting it to True enables the building of functional tests. The default value is True.
            build_doc=[True | False]. Setting it to True enables the building of rst files to generate HTML files for updated documentation. The default value is False.
