Hi Satish, yes the -m64 flag tells the compilers the target cpu is intel 64. <br>

The only reason I'm trying to get PETSc working with intel is that the bundles for the software we release use Intel compilers for Linux, Mac and Windows (OneAPI intelMPI for linux and Windows, OpenMPI compiled with intel for MacOS). I'm just trying to get
PETSc compiled with intel to maintain the scheme we have and keep these compilers, which would be handy if we are to release an alternative Poisson solver using PETSc in the future.

<div class="PlainText">Ops - for some reason I assumed this build is on Mac M1. [likely due to the usage of '-m64' - that was strange]..<br>
<br>
But yeah - our general usage on Mac is with xcode/clang and brew gfortran (on both Intel and ARM CPUs) - and unless you need Intel compilers for specific needs - clang/gfortran should work better for this development work.<br>
