[petsc-dev] Build petsc-3.2 with "mpicc -cc=icc"

[Lisandro Dalcin]

This is just a report from a little experiment, and wanted to throw
the results here:

I'm trying to build with Intel compiler re-using my distro's (Fedora
15) MPICH2 1.4 built with GCC. My configure command line was:

$ cat arch-intel-c/conf/reconfigure-arch-intel-c.py
#!/usr/bin/python
if __name__ == '__main__':
  import sys
  import os
  sys.path.insert(0, os.path.abspath('config'))
  import configure
  configure_options = [
    '--COPTFLAGS=-O3',
    '--CXXOPTFLAGS=-O3',
    '--FOPTFLAGS=-O3',
    '--with-c2html=0',
    '--with-cc=mpicc -cc=icc',
    '--with-cxx=mpicxx -cxx=icpc',
    '--with-debugging=0',
    '--with-fc=mpif90 -fc=ifort',
    '--with-shared-libraries=1',
    'PETSC_ARCH=arch-intel-c',
  ]
  configure.petsc_configure(configure_options)


However, for some reason cmake failed to indentify de compiler, the
relevant block from configure.log is pasted below. I'm wondering if
the FILEPATH thing is the cause of the failure...

Anyway, configure continued and I was able to use the legacy make
build, with a lot of outputs like the one below:

$ make
...
libfast in: /home/devel/petsc/3.2/src/mat/impls/transpose
icc: command line warning #10120: overriding '-O2' with '-O3'
libfast in: /home/devel/petsc/3.2/src/mat/impls/transpose/ftn-auto
icc: command line warning #10120: overriding '-O2' with '-O3'
libfast in: /home/devel/petsc/3.2/src/mat/impls/python
icc: command line warning #10120: overriding '-O2' with '-O3'
...

Anyway, "make test" worked (however, it generated a bogus error
because the compiler complained with the same line as above)

My "ldd" output looks a bit messy, and despite using ICC and having
MKL available, configure didn't pick MKL (perhaps this could be a nice
feature?)
