Re: 8.0.5 32-bit on HP-UX 11.0 64-bit

Hi Baton/Marcin (who wrote?),

in your subject line you wrote that 8.0.5 32-bit has problems. Now, it is called 32-bit because its address range only has 32 bits width. That means, you only can address 2^32 bytes of virtual memory per process, which is exactly 4 GB.

In a 32-bit mode you *cannot* access 17 GB of virtual memory by a single process. It is a mathematical limitation in itself. However, several processes together may map their virtual memory areas to different parts of the physical 17 GB memory thus exploiting all of it.

You put a truck engine into a Porsche and now you wonder the Porsche doesn't move any more.
