Intel C++ Compiler in HPC toolkit for OpenMP offload functionality

chang__tao — Tue, 10 Dec 2019 17:21:00 GMT

Hello,

Recently I followed the guide on this website: https://software.intel.com/en-us/articles/openmp-50-target-with-intel-compilers to compiler OpenMP offload codes with icpc in OneAPI HPC Toolkit.

However, after the installation of OneAPI Base Toolkit and OneAPI HPC Toolkit, there are only icc and icpc compilers without -qnextgen flag. Instead, I found two compilers icx and icpx, which integrate the nextgen functionality.

I wonder if the compiler mentioned in the guide is icpx?

Thanks in advance.

Hi Tao,

The compiler mentioned in the document is icc/icpc . You can use -qnextgen flag with icc/icpc which then supports OpenMP target feature.

I have checked on the devcloud which has Beta3 version of OneAPI Base Toolkit and OneAPI HPC Toolkit installed , and both icc and icpc is working fine with -qnextgen.

Let us know if this helps.

Thanks
