Check `icc` ```shell= [oran@localhost ~]$ icc --version icc (ICC) 2021.4.0 20210910 Copyright (C) 1985-2021 Intel Corporation. All rights reserved. ``` 2. Check `icpc` ```shell= [oran@localhost ~]$ icpc --version icpc (ICC) 2021.4.0 20210910 Copyright (C) 1985-2021 Intel Corporation. All rights reserved. ``` 3. Check `iccvars.sh` ```shell= [oran@localhost ~]$ which iccvars.sh /opt/intel/oneapi/compiler/2021.4.0/env/iccvars.sh ```
