A girl I know wrote gullible on the ceiling of her school. She kept telling people that the word was written on the ceiling - Charlie Demerjian
The Sun user has ordered a dual 244 box and wanted to ask if a 32-bit user space application can use the 4GB memory that Opterons address. That, he suggests could help his company save money by not buying another Sun box.
An extra 1GB memory per process would, he suggests, help his firm in the short term until the closed source software vendors get their X86-64 port act together.
His question was almost immediately answered by Richard Brunner, a fellow at AMD. He said that for SLES8 AMD64, "32-bit userland" does get practically all the entire 4GB virtual address space, without worrying about overheads of AGP or PCI.
He adds: "We have plenty of 32-bit programs that have used the extra space".
No wonder that Sun prefers Intel's Xeons as entry level options, we would tactfully suggest.
