Hi - I'd like to run this OCaml program:

       http://www.cs.utah.edu/~hal/megam/<http://www.google.com/url?sa=D&q=http://www.cs.utah.edu/%7Ehal/megam/&usg=AFQjCNHB7epkdYpt-s4xTcYEn08rjFVv9g>

on the 3TB memory supercomputer described here


http://www.ncsa.illinois.edu/UserInfo/Resources/Hardware/SGIAltix/Tec...<http://www.google.com/url?sa=D&q=http://www.ncsa.illinois.edu/UserInfo/Resources/Hardware/SGIAltix/TechSummary/&usg=AFQjCNE-j5ESYpWkNcp516iaiCwl6qXtnw>

It appears that the OS, SGI ProPack 6

       http://www.sgi.com/products/software/linux/propack.html<http://www.google.com/url?sa=D&q=http://www.sgi.com/products/software/linux/propack.html&usg=AFQjCNFiosQdkaP9Ufb5oFbjIOEto94QMg>

is a version of Linux, but the 64-bit Linux compilation we produced
using the OCaml 3.10 compiler gives this error message:

       Exec format error. Binary file not executable.

I'm not sure where to go from here.   The compilers available for the
machine are listed as:

       Intel 10.1: Fortran77/90/95 C C++
       GNU: Fortran77 C C++

so if there were an OCaml to Fortran, C, or C++ translator we might be
able to go that route.  Anybody know of one?  On the other hand, I
know there's been some use of OCaml in scientific computing, so maybe
someone has a better idea?

Seen that before: looks like you're trying to run an x86_64 binary on  
an Itanium machine.
You would have to build O'Caml on that machine and compile your code  
there.  Last time I tried O'Caml on Itanium Linux (that was RHEL 4  
about a year ago) everything worked just fine.
Hope this helps.

It looks like you are trying to run Pentium executables on an Itanium
machine.  If the supercomputer is available for compiling, you should
bootstrap and install OCaml on that machine, otherwise you'll need to
find a smaller Itanium-based machine to compile your program (and hope
the executables will be compatible), or make a cross-compiler to run
on your PC.

Making a cross-compiler is quite a lot harder than installing OCaml on
the target machine directly, but you have a how-to here:
