Does the fortran compiler run on 64 bit machines (like itanium) using Linux?

Does the fortran compiler run on 64 bit machines using Linux?

[Lahey Support]

We do not officially support LF95 on 64 bit machines but it will work.

It will work on an Opteron if you compile with "-Wa,--32" so that the assembler works with 32 bit objects created by LF95. The 32-bit version of gcc should be installed to provide the necessary libraries and objects. -NTRAP is an example of functionality that does not work. There may be other problems. Use at your own risk.

Polyhedron in the UK has recently posted benchmarks for the Opteron, and one of the compilers tested is Lahey's 32 bit Linux compiler running on an Opteron machine with a 64-bit Linux operating system, SuSE I believe. Does anyone know if OpenMP works in this environment on a multiprocessor machine? Has anyone tried it?
