Subject: [Mantevo-developers] Intel Fortran on MS Windows via Parallels
	Virtual PC on a Mac
Message-ID: <C315A347.2F7D1%maherou@sandia.gov>
All,
Just in case you are interested, I thought the results below were
interesting.  I have installed the Intel Fortran compiler for Windows on a
Windows XP virtual machine using Parallels on my dual core Intel Mac.  The
Linpack benchmark was part of the package so I ran it.  The results are
really quite impressive on a single core while the second core is
essentially useless.  On a single core, I get almost 5 GFLOPS.  I don't have
a similar set up on the Mac side, so I can't do a comparison with native
Mac, but it's still interesting.
Mike
