[petsc-dev] KNC build?

[Richard Mills]

Hi Mark,

I noticed that you are using the wrong compiler wrappers.  Instead of
'mpicc', 'mpif90', and 'mpicxx' (which will invoke GNU compilers), you
probably want 'mpiicc', 'mpiifort', and 'mpiicpc' (invoke the Intel
compilers).

You will probably also want to unload the IMPI 5.x and load the IMPI 4.1.3
module right now because of a stupid bug in the compiler wrappers (for
which I've filed a bug report--will be fixed in next IMPI release, sometime
before SC14).
