For most users, this should not be a noticeable change. Modern versions of the PGI compilers (version 19.1 and later) switched to using a LLVM-based back-end for code generation, instead of the PGI-proprietary code generator. Pgi/20.1: LLVM back-end for code generation In function `.': undefined reference to `std::_cxx11::basic_string, std::allocator >. For complete support of the C++11 and later standards with the PGI 20.1 and later compilers do this after the PGI compiler module is loaded:Ī symptom of broken compatibility is unusual or non sequitur compiler errors typically involving the C++ standard library especially with respect to templates, for example: The most noticeable aspect of interoperability is that some parts of some C++ standards are available by default in various versions of the PGI compilers other parts require you to load an extra module. On OSC clusters the only mechanism of control is based on modules. We call this PGI and GNU compatibility and interoperability in analogy with the Intel compilers' terminology. PGI compilers use the GNU tools on the clusters: header files, libraries, and linker.

If you would like to install the PGI compilers on your local computers, you may use the PGI Community Edition of the compiler for academic users for free at here. The PGI Compilers are available to all OSC users. You can use module spider pgi to view available modules for a given machine. Feel free to contact OSC Help if you need other versions for your work.
