imapilot : 27/10/03 10:09 PM : Incident created

- I have installed Linux 9.2 on a dual Opteron system (2x Opteron 242) used for number crunching. The kernel is the standard 2.4.22-10mdkenterprise kernel. I am seeing an excessive amount of memory being used by the kernel (??). Immediately after boot, even without running the X server, the OS has already claimed 1.2G of the 2G available. My code execution requries 800M per instance, I usually run 2 instances. I noticed the problem because with 2 code instances running, the machine was swapping like mad, so the memory usage is real, it's not cached, it's not buffered, the kernel / OS has really sucked up 1.2G of memory. This seems a bit excessive. Do I need to do anything special for AMD Opteron configuration??
thanks
Matt Knapp
