Hi,
    I'm a frequent user of the SGI Origin 2000 Supercomputers at the
National Center for Supercomputing Applications.  I was testing one of
my codes on an IA-64 machine at the Compaq testdrive site.. They have
sgif90 installed on those machines in addition to sgi linux.  However..
I can not use the -O3 or the -Ofast compiler optimizations.. this breaks
my code or I get wierd error messages.. These optimizations work fine on
the Origin.. and this leads me to believe it's the compilers fault.  Do
you know whether other people have had a similar fate and can you help
me over come this.  I can compile with optimizations of -O2 which is
encouraging and the program works fine.  Also, the InterProcedural
linking optimizations ( -IPA ) are not working either.. the compiler is
looking for some sort of executable however this executable ipa***
doesn't exist.. a file with the extention ****.so does however..  The
-IPA option 1/2's the run time on the Origin supercomputers.. do you
know the state of the -IPA option and if it works or will work.  Any
help you can give me is much appreciated.. and I'm rather pleased with
the performance as of now.  I hope to squeeze much more out of all of
your hard work.  Thanks you...
