Issue with intel's cluster openmp

[Micha <michf@post.tau.ac.il>]

I'm trying to run intel's cluster openmp on my machine. For some reason it
crashes with a SIGBUS (Bus Error) when I run it on my machine. The exact same
executable with the same libraries works fine on a different one (although it
is itanium).

I'm guessing that I got some memroy configuration wrond in the kernel. I got
some reference that /proc/sys/kernel/randomize_va_space needs to be set to zero
but that doesn't seem to help.

Running the program (a very simple hello world program) through strace shows
that it's crashing at

--- SIGBUS (Bus error) @ 0 (0) ---
+++ killed by SIGBUS +++

My guess is that mmpat with MAP_FIXED is what's crashing (it depends on the
program always using the same memory addresses for dynamic memory).

I'd be glad for any ideas

Thanks
