According to the software's overview page:
Hypre is a library of fast linear solvers, parallel preconditioners and multigrid algorithms designed with the intent to solve large scale, detailed problems.
Using Hypre on RCC Resources
Using gnu is not necessary. These libraries are also available to other compilers. Using a different compiler will simply mean linking and including a different path, for example:
-I/opt/hpc/<compiler>/include/hypre -L/opt/hpc/<compiler>/lib64/ -lHYPRE_struct_ls
