You're still missing the first part of the file.

You also need to grab kernel.gz.boot from the boot.flp image.

Then you can do a:

  cat kernel.gz.boot kernel.gz.aa kernel.gz.ab > kernel.gz

Take a look at src/release/scripts/split-file.sh to see how these files are
generated.

Useful if you want to do an install with a custom kernel, without
building a whole release.

Re: Reading rc.conf from C programs?

You could perhaps copy the way that "The Fish" does it?

Take a look at "ports/sysutils/thefish".

The "parser.c" code appears to read /etc/{,defaults/}rc.conf and place
all the options into a linked list.

Install the pvm port (ports/net/pvm) on the machines.

I've played around with this a bit, and it's quite fun to watch.
Check out the X11 fractal demo ("xep").

There's also a port of povray (ports/graphics/pvmpov) which uses PVM
to distribute it's processing.

quota and NFS

2000-11-28 Thread Matthew West

Who do I prod to get someone to take a look at bin/12939 and bin/6183?

I've been using both patches now since FreeBSD 4.0 and they make life
a lot more pleasant when using quota on a machine with NFS mounts.

Re: Can anyone recommend a good clustering software?

2000-07-11 Thread Matthew West

A quick search on http://www.google.com/ returned: 

http://www.sc.cs.tu-bs.de/pare/:
"PaRe is an educational project at the Technical University Braunschweig to
set up a Beowulf-class supercomputer built from commodity components. It
starts from early hardware and design decisions and ends in building and
profiling some small parallelized applications."

When talking about "clustering", you should mention whether it's related to
parallel computing or fail-over/high-availability.

For more information on Beowulf-style clusters, take a look at:
http://www.beowulf.org/

For a Beowulf-style cluster with a FreeBSD spin on it:
http://acme.ecn.purdue.edu/

I've set up a PVM-based cluster on FreeBSD.  It's pretty straight forward:

Basically, it's just a FreeBSD base install and the PVM package (which is in
the ports collection).  A PVM enabled povray is also available in the ports
collection, but I've not had a chance to play with it yet.
