[Pw_forum] Installation of QE on 20-processor MAC XServe cluster

[Gabriele Sclauzero]

Dear Mark,

   from my experience I would say that there is not much difference in installing QE on a 
multicore Mac with OSX or on a Linux machine if the environment is sane and properly 
configured (including shell, compilers, libraries, MPI, ...).
At least I have tried on a dual core Macbook with Leopard and I didn't find much difficulty.
In order to install a parallel version of QE you first must be sure that you have a 
working MPI compiler. Once you are sure of this it should not be difficult, if you 
encounter problems they are likely to be answered in the FAQ or troubleshooting of the 
wiki or on the user guide.

A general advice is that you should avoid ATLAS (nad maybe also LAPACK) libs coming with 
the OSX bundle.

If you want further help, please post more info.

Regards,


GS
