Runtime libraries for POSIX pthreads support

There are two runtime libraries that are connected with POSIX thread support. The libxlf90_r.so library is a threadsafe version of the Fortran runtime library. The libxlsmp.so library is the SMP runtime library.

Depending on the invocation command, and in some cases, the compiler option, the appropriate set of libraries for thread support is bound in. For example:
Command Libraries Used Include Directory

xlf90_r
xlf95_r
xlf_r

/opt/ibm/xlf/15.1.6/lib/libxlf90_r.so

/opt/ibm/xlf/15.1.6/lib/libxlsmp.so

 /opt/ibm/xlf/15.1.6/include
