Only installed hpc toolkit. Are the samples in Base toolkit?
There are some samples here, although most are in languages other than Fortran.
As best as I can tell, Intel has not updated the "Samples Bundle" for oneAPI, so you need to look at the Parallel Studio XE Samples Bundles that you can find here: Windows, Linux, Mac.
The samples for oneAPI products are on GitHub. Unfortunately, there are no Fortran samples there yet. Use the link Steve provided for Fortran.
