When you say "largefile" exactly what size is this large file? In the
filesize jargon a "largefile" means a file larger than 2GB in size.
That size overflows a 32-bit integer and needs special handling to
work on 32-bit systems. So I can't tell if you just mean a big file
such as 500MB or really a largefile such as 3GB.

Cool box! I am also using an ia64 box, a dual processor hp-i2000, but
I am running Debian GNU/Linux on the ia64 here.
But then I guess my statement about "largefile" size is meaningless.
But I wanted to ask anyway since it might spark an idea of someone.
It is only important if you have 32-bit longs.
The IA64 Linux platform is an LP64 model with 64-bit longs, 64-bit
pointers and 32-bit ints. So it should be able to work with very
large files without any special handling.
