Hi Chris, I've done that here for GCC 4.9.3: configopts = "--with-arch=westmere --with-pkgversion=%s-guillimin --with-bugurl=http://www.hpc.mcgill.ca/starthere"%version languages = ['c', 'c++', 'java', 'fortran', 'go']
then we see in gcc -v: Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/sb/software/CentOS-6/eb/software/Core/GCC/4.9.3-binutils-2.25/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.9.3/lto-wrapper Target: x86_64-unknown-linux-gnu Configured with: ../configure --with-arch=westmere --with-pkgversion=4.9.3-guillimin --with-bugurl=http://www.hpc.mcgill.ca/starthere --enable-languages=c,c++,java,fortran,go --enable-lto --enable-checking=release --disable-multilib --enable-shared=yes --enable-static=yes --enable-threads=posix --enable-gold=default --enable-plugins --enable-ld --with-plugin-ld=ld.gold --prefix=/software/CentOS-6/eb/software/Core/GCC/4.9.3-binutils-2.25 --with-local-prefix=/software/CentOS-6/eb/software/Core/GCC/4.9.3-binutils-2.25 --enable-bootstrap --with-cloog=/dev/shm/GCC/4.9.3/dummy--binutils-2.25/gcc-4.9.3/stage2_stuff --with-isl=/dev/shm/GCC/4.9.3/dummy--binutils-2.25/gcc-4.9.3/stage2_stuff Thread model: posix gcc version 4.9.3 (4.9.3-guillimin) the default does not set --with-arch but many easybuilds use it via the optarch setting. For now I am just compiling everything on westmere nodes (I am also just starting with easybuild) but I could also create two sets of modules, one for westmere and one for sandybridge (we also have some ivybridge but that is not worth the effort optimizing for).
