Dear Reinaldo

We're using Intel P4 processors with 64 bit extension and x86_64 Linux,
which works fine. I ran some benchmarks on a dual-CPU Opteron machine
last year with the same 64 bit adf binaries (which were compiled on the
Intel em64t system) under x86_64 Linux; no problems occurred. Using the
-mcmodel=large option for the Intel F90 compiler it is also possible to
compile a x86_64 bit code that can actually use more than 2 GB of RAM. I
just completed an NMR calculation that used 4 processors and between 3 and
4 GB of RAM per processor.
