The two PGI licenses share tools and other licensed components, and even
though you may be able to do some things with one license and some things with the other, the full content of both licenses will not be available when served by the same server.
As a result, we say that you cannot ‘serve’ two PGI licenses with the same license server.
It will probably work to point to one license when using Fortran, and one license
when using C/C++, but we are not sure the two can be used at the same time
by two different requests.
