How to run the example code in onedal in oneapi (k-means).

[GTC]

You can show the steps to execute k-means in the onedal sample code, and how to build the project.

I had a lot of problems executing the sample code.

Don't know how to build projects.

How to write the corresponding cmake code. Can you show the corresponding example?

You could look at the oneDAL Getting Started Guide follow the link:

https://www.intel.com/content/www/us/en/docs/onedal/get-started-guide/2024-0/overview.html

please check there how to Build and run the examples from oneDAL as an example

# Navigate to the directory containing examples and then build them:

cd /examples/oneapi/dpc

make so example=svm_two_class_thunder_dense_batch # This will compile and run Correlation example using Intel(R) oneAPI DPC++/C++ Compiler

make so mode=build # This compiles all examples in the current directory

or you could look at the build applications with oneDAL follow another oneDAL Developer Reference & Guide:

here are an outputs I see while building against the current version of oneDAL ( 2024.2) :

echo $DALROOT 

/opt/intel/oneapi/dal/2024.2/

Compiling:

icpx -std=c++11 -I"/opt/intel/oneapi/dal/2024.2/include" kmeans_csr_batch.cpp \

/opt/intel/oneapi/dal/2024.2/lib/libonedal_core.a /opt/intel/oneapi/dal/2024.2/lib/libonedal_thread.a -ltbb -ltbbmalloc -lpthread -ldl
