Subject: Re: [gem5-users] mmap error when I increase mem-size
Hi Andreas,
We have got some clue on this issue. The problem was that I was using 32-bit OS.
In 32-bit version, it has a limit on the amount of memory which can be
allocated per process.
The theoretical limit is 4GB. Due to this, even though my system had 16GB of
RAM, it was giving mmap error when I tried to use mem-size = 4GB. (The same
code worked well for 2GB mem-size on 32-bit machine itself).
Here's where I found the details :
https://help.ubuntu.com/community/32bit_and_64bit
I just got the OS upgraded to 64-bit on the same machine, and things are smooth
now!

Hi Mahmood,
My OS is ubuntu 12.04 LTS, glibc is 2.15-0ubuntu10.5 and g++ is 4.6.3 and the
machine has 16GB RAM and a swap space of 25GB. (9GB from partition and 16 GB
from swap file )
The same code works well in another machine with 32GB RAM.

Anju,
First you have to find is it a system related problem or gem5 bug.
What is your OS? G++? GLIBC?
