Dear users,

I have installed intel parallel studio on my workstation and  thus I would like to take advantage of intel compiler.

Before messing up my installation, have you got some guidelines to survive at this attempt? I have found here in the mailing list the following instructions:

--with-cc=icc --with-fc=ifort --with-mpi-include=/path-to-intel --with-mpi-lib=/path-to-intel

Are they correct?
I think so. But you may also add PETSC_DIR=/path-to-petsc PETSC_ARCH=name-for-this-build


Also I have an already existing and clean installation of petsc using openmpi. I would like to retain this installtion since it is working very well and switching between the two  somehow. Any tips on this?
Use PETSC_ARCH in PETSc configure to differentiate different builds, and export PETSC_ARCH in your environment to select the one you want to use. See more at https://www.mcs.anl.gov/petsc/documentation/installation.html


I will never stop to say thank you for your precious support!

Edoardo
