The machine has OpenMPI installed in it, but no BLAS. Can I configure petsc somehow without having any BLAS commands? If not, can I install BLAS somehow only on my own folder (/home/myfolder) without touching anything inside /usr/ folder?

  Of course, PETSc NEVER requires you to have any kind of root access to install it and its packages. Just use --download-fblaslapack as a ./configure option. It will keep the BLASLAPACK inside the PETSc directory with the PETSc libraries.
