hi,
After I installed a newer version of Kernel (2.4.2) and enable DMA option in
hardware configuration, the behavior changes.
I can see performance improvements when another thread is used. Also, i can
see timing overlaps between two threads. i.e. when one thread is blocked on a
page fault,

Another observation. I have two independent programs. One program incurring
page faults and another program just doing some work.

Hi,
I am a graduate student at Univ Of Illinois at Urbana-Champaign.
Regarding my thesis, I need some help with running a multithreaded program on
red hat linux. I am experimenting with paging behavior. I use a machine where
swap space is large compared to available memory. I run two threads,
