Parallel Processing is not currently part of the mainstream linux kernel.
I have an openmosix patched kernel at http:/gnuveau.net under open-source
software downloads.  It supports parallel processing and global shared
memory.  you could use nfs for the disks.  Not sure about the networking.

Enjoy,
Scott

Building server-farm

[Wiktor]

Hi,

I'm looking for a way to connect multiple linux systems into one big 
machine (server-farm) and I can't find any way of enabling it in kernel. 
  Is this feature supported? If not, how can I build cluster from, let's 
say, 5 machines (I'm interestied in sharing of processes, memory, disk 
space and network interface). Thanks for replies.

You'll can use OpenMosix 
(http://sourceforge.net/project/openmosix) or Mosix 
(http://www.mosix.org/).

Have a look at:
http://www.mini-itx.com/projects/cluster/
http://en.wikipedia.org/wiki/Beowulf_%28computing%29
http://de.wikipedia.org/wiki/BeowulfProject2004 (German, it describes 
howto setup a cluster)

It seems that you have to analyse your problem a bit more.

There are 5 main types of clusters (or server-farms as you call it):
- parallel computing
- high availability
- load balancing
- storage cluster
- database cluster

Of course these overlap in functionality but so they say :) In many 
cases those goals are achievable with "share nothing" in kernel level: 
lam/mpi, ipvs, hartbeat, lvm etc. Well, about filesystems I am not sure 
at moment :)

Please analyse your need to create "as it was one big machine" because 
maybe it is not the solution you really need.

thanks,
Indrek

Re: Building server-farm

[Wiktor]

Hi,

see, in fact it is not huge commercial solution what i need - i'm 
interested in squeezing every single electron from machines i have in 
school, and i thought that for some applications cluster is the best 
method of sharing computing power. i'm not thinking (yet) about 
optimizing it to some particular function. i simply wanted to know how 
clustrer works and how it makes use of multiple machines. but, the 
system has to satisfy one limitation - it must be completly usuable in 
floppy-booting mode (machines i can use are normally used under control 
of Micro$oft (r) Win*** (tm) eXPloit Sewer and i cannot reinstall their 
systems without being sucked from school, so i can incorporate them into 
cluster only by booting system from another medium, prefferably from 
floppy). as far i've tested openMosix, and it works quite good. maybe in 
future i will be given a real server-farm, where i could set up 
everything sane. but now i need only links to some solutions, so i can 
test them.
thanks for your help
