Thanks everyone for the answers!
We have a small enhancement in the works, and will send it to the
various projects maintaining the libdwarf code.

Open Grid Scheduler - The Official Open Source Grid Engine
Hi,
I need some changes in libdwarf, and I was wondering where I can
discuss ask devel related questions.
The original maintainer was John Birrell, who left us in 2009:

The way other OSes handle this is by detecting any abnormal amounts of
faults (sometimes it's not the fault of the hardware - eg. when a

Because the kernel is lazy!!
You can google for lazy algorithm, or find an OS internals book and
read about the advantages of doing it this way...

No, I would say ELF is somewhat documented.

I am wondering if it is useful to have a secure file flag??
The secure file flag will be set for files that contain sensitive data.
Then the OS will take special care when operating on those secure
files.
e.g. when deleting a secure file, the OS will overwrite the file with
random data.

You can search for freebsd in the archive:

If you are going to build clusters with over 1000 nodes, you should
then install a batch system instead of using kernel-based clustering
services.

There are many clustering projects, espectially for Linux. One
interesting project is the Single System Image Clusters for Linux.

But how much tuning is needed? You can download a kernel patch for VM,
another kernel patch for FS...
I am sure Linux can be even faster on an SMP machine with a Journaling
FS (XFS, RFS, JFS, ext3, etc).
