[petsc-users] IMPI with Hypre

  *   Its easier to just add the newer version of gcc/g++ compilers to PATH

Except that I do my path loading through environment modules (lmod version) and they do not allow multiple compilers to be loaded at the same time.

But yes, that would work.

Its easier to just add the newer version of gcc/g++ compilers to PATH - and icc will pick it up [without requiring -gcc-toolchain option]

export PATH=/location/of/newer/g++/bin:$PATH
./configure ...
make ...
