What's the difference between icx, icl and icc compilers?

[SamKolton]

Hi!

I'm currently utterly confused what's the difference between `icx.exe`, `icl.exe` and `icc` on Linux? What should I use to develop C++ code?

Thanks!

Hi,

Thanks for reaching out to us!

ICC (Linux), ICL (Windows) are classic Intel C/C++ Compilers. Whereas, ICX is Intel nextgen compiler based on Clang /LLVM technology plus Intel proprietary optimizations and code generation.

• You may use ICC for performance on CPU targets.
• ICX enables OpenMP TARGET offload to Intel GPU targets.

For more details please refer the below link.

Thanks Goutham!

Am I correct that `icl` and `icc` are independent of `icx` and neither of them invokes each other?

Yes, you are correct.

Thanks,
