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:
