7  # a) Processor specific flags:  #                         http://www.sgi.com/products/servers/uv/specs.html)
8  #    1) for more speed on Core2 processors replace -xW with -xT  # a) For more speed, provided your data size does not exceed 2GB you can
 #    2) for more speed on Pentium4 based EM64T processors replaces -xW with -xP  
 # b) For more speed, provided your data size doesn't exceed 2GB you can  
9  #    remove -fPIC which carries a performance penalty of 2-6%.  #    remove -fPIC which carries a performance penalty of 2-6%.
10  # c) Provided that the libraries you link to are compiled with -fPIC this  # b) You can replace -fPIC with '-mcmodel=medium -shared-intel' which may
11  #    optfile should work.  #    perform faster than -fPIC and still support data sizes over 2GB per
12  # d) You can replace -fPIC with -mcmodel=medium which may perform faster  #    process but all the libraries you link to must be compiled with
13  #   then -fPIC and still support data sizes over 2GB per process but all  #    -fPIC or -mcmodel=medium
14  #   the libraries you link to myst be compiled with -fPIC or -mcmodel=medium  # c) flags adjusted for ifort 12.1.0
 # e) Changed from -O3 to -O2 to avoid buggy Intel v.10 compilers. Speed  
 #   impact appears to be minimal.
