You write:
In Linux, nothing much changes for the user programs. They are
still limited to 3 GB each. To use all 64 GB of a fully-loaded PAE
system, then, you need at least 21 processes that each take 3 GB
of memory. (3 * 21 = 63 GB; the remaining 1 GB belongs to the
kernel.)
Of course a single-process can use more than 3GB of memory by using
shared memory and mapping and unmapping parts of the memory as
needed. This is what SAP R/3 will do on Linux 2.4.
