How about the memory limitations for linux?

As a system admin, you should aware of maximum amount of memory and CPU
that supported by Linux system. This is an essential task and you must
consider at least AMD and Intel platforms.

Intel x86
* Maximum CPUs: 32 (including logical CPUs)
* Maximum memory: 64GB
* Maximum filesize: 8TB
* Maximum filesystem size (ext3): 16TB
* Maximum per-process virtual address space: 4GB

AMD 64/EM64T
* Maximum CPUs: 64
* Maximum memory: 128GB
* Maximum filesize: 8TB
* Maximum filesystem size (ext3): 16TB
* Maximum per-process virtual address space: N/A

Please note that these are standard limitations and do not get confused
with Linux cluster systems. For up-to-date information please refer to
Linux kernel documentation located at /usr/src/linux/Documentation.
