<div><br>
</div>
<div>I have installed intel parallel studio on my workstation and thus I would like to take advantage of intel compiler. </div>
<div><br>
</div>
<div>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:</div>
<div><br>
</div>
<div>--with-cc=icc --with-fc=ifort --with-mpi-include=/path-to-intel --with-mpi-lib=/path-to-intel <br>
</div>
<div><br>
</div>
<div>Are they correct?<br>
</div>
</div>

<div>I think so. But you may also add PETSC_DIR=/path-to-petsc PETSC_ARCH=name-for-this-build</div>

<div>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? </div>

<div>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.
