Compiling Kernel with Intel DPC++
To compile a kernel using Intel DPC++ (basically Clang LLVM) with the specified flags -O3 -march=native -mtune=skylake -mavx2, follow these steps:
- Ensure that you have the Intel DPC++ compiler installed on your system.
- Create a new source file for your kernel, e.g.,
kernel.cpp. - Write your kernel code inside the source file, ensuring it is properly formatted according to the programming language, including indentation and tabulation as needed.
- Save the file and open a terminal or command prompt.
- Navigate to the directory containing your source file.
- Compile the kernel using the Intel DPC++ compiler with the specified flags:
- After compiling the kernel object file (
kernel.o), you can link it with the host code and other libraries as needed to create an executable. - Save the executable with a desired name, e.g.,
my_kernel_executable.
dpcpp -O3 -march=native -mtune=skylake -mavx2 kernel.cpp -o kernel.o
