 Posted: Thu Jan 15, 2004 11:35 pm Post subject: Enabling shared memory? |
 |
|
Can someone please explain to me what shared memory in Linux means? When I issue the command 'free', it always says shared = 0. I thought that if I'd open something like three Konsole windows, they would share memory, but they don't. Shared stays at 0.
I did some Googling and found out that it was formerly called SHM and you should mount it by hand. Since I'm running kernel 2.6, I wonder what it's called now, and how I can enable it.
Am I thinking totally wrong by saying that three Konsole-s could share memory? I'm not a real newbie to Linux, but I just can't seem to find out what this shared memory means and how I enable/use it. Will the kernel automatically detect that I start three Konsole-s and arrange the swap pages accordingly?
I've got so many questions and few answers. |

To answer part of your question:
| man free wrote: | free displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel. The shared memory column should be ignored; it is obsolete.
