Isn't Xeon5110 64bit? Maybe you could just put a 64 bit OS in you box. Also, take a look at http://www.spack.org/wiki/LinuxRamLimits -- Walter Isart Montane wrote: > I've got a dual Xeon. Here you are my cpuinfo. I've read the limit on > a 2.6linux kernel is 4GB on user space and 4GB for kernel...

Re: 2GB limit on 32 bits

2007-11-09 Thread Walter Underwood
Some OSs split that 4GB into a 2GB data space and a 2GB instruction space. To get a 64bit address space, the CPU, OS, and JVM all need to support 64 bits. There have been 64 bit Xeon chips since 2004, the Linux 2.6 kernel supports 64 bit, and recent JVMs do, too. If your Xeon supports 64 bits, you

Hi norberto, i've tried a simple C app to maloc 2GB and it doesn't works (the same with 1.5Gb works) so it seems to be a kernel problem. The server is a FC5 with this uname -a Linux X 2.6.18-1.2239.fc5smp #1 SMP Fri Nov 10 13:22:44 EST 2006 i686 i686 i386 GNU/Linux Any ideas how to reach the

I've got a dual Xeon. Here you are my cpuinfo. I've read the limit on a 2.6linux kernel is 4GB on user space and 4GB for kernel... that's why I asked if there's any way to reach 4GB per process. Thanks anyway :( cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family
