How is Boost loaded?

Use 'module load' to load the boost module on Coeus.  The default boost module links to gcc-13.2.0.  You will probably also want the gcc compiler, so 'module load gcc' also.

$ module load gcc

$ module load boost

$ module list

Currently Loaded Modules:

  1) glibc/2.34-gcc-13.2.0-dtclx3b           3) boost/1.85.0-gcc-13.2.0

  2) gcc-runtime/13.2.0-gcc-13.2.0-24uno5v   4) gcc/13.2.0

How is Boost invoked?

Boost is not invoked, it is external libraries, not an executable. To Use the boost libraries in a C++ program, simply load the module and include the headers in your code.
