 ## Compilers
 
-### ifort Intel
+### Intel oneAPI
 
-Be sure you have the
-[Intel Parallel Studio Cluster Edition](https://www.scivision.dev/install-intel-compiler-icc-icpc-ifort/)
-that has `mpiifort`.
+[Intel oneAPI](https://www.scivision.dev/intel-oneapi-fortran-install)
+has essentially complete Fortran 2018 support.
+Use Intel compilers  (oneAPI or Parallel Studio) by:
 
-```bash
-FC=ifort CC=icc CXX=icpc cmake ..
-```
+
+* MacOS or Linux:
+
+    ```sh
+    FC=ifort CC=icc ctest -S setup.cmake -VV
+    ```
+* Windows
+
+    ```post
+    set FC=ifort
+    set CC=icl
+
+    ctest -S setup.cmake -VV
+    ```
 
 ### Flang / Clang
 
 [Flang](https://www.scivision.dev/flang-compiler-build-tips/) is a Free compiler.
 
 ```bash
-FC=flang CC=clang CXX=clang++ cmake ..
+FC=flang CC=clang ctest -S setup.cmake -VV
 ```
 
-### PGI
+### Nvidia HPC SDK
 
-[PGI](https://www.scivision.dev/install-pgi-free-compiler/) is available at no cost.
+[Nvidia HPC SDK](https://www.scivision.dev/install-nvidia-hpc-free-compiler)
+is available at no cost.

-## Bugs
-
-### iso_fortran_env
-
-Flang 6 and PGI 18.10 seem to have a bug with `iso_fortran_env` that doesn't allow `compiler_version` and `compiler_options` to work unless `use iso_fortran_env` is ONLY used in `program` and NOT `module` *even if* using `only`.
-Thus, simple programs like `pragma.f90` work, but not the usual programs to print the compiler versions and options with Flang and PGI.
