Mamikonyan" Organization: Department of Physics, Drexel University X-Mailer: Mozilla 4.77 [en] (X11; U; Linux 2.4.5 i686) X-Accept-Language: en MIME-Version: 1.0 To: linux-kernel@vger.kernel.org Subject: increasing the TASK_SIZE Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I was wondering how I can increase the process address space, TASK_SIZE (PAGE_OFFSET), in the current kernel. It looks like the 3 GB value is hardcoded in a couple of places and is thus not trivial to alter. Is there any good reason to limit this value at all, why not just have it be the same as the max addressable space (64 GB)? We have an ix86 SMP box with 4 GB of RAM and want to be able to allocate all of it to a single program (physics simulation). I would greatly appreciate any help on this. Thanks a great deal, Ernie PS. Please `CC' me the answer! /_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ Ernest N.
