Creating a cluster

[Mathias Gibbens]

Hi all,

Is there a way to create a cluster so that you can spread one 
process across many computers, thus creating something like one 
super processor, and not many single processors? Thanks,

Not for just any random process: if you want to spread a single task
over a lot of systems your software should be written to support such
a scenario, if possible, for instance by using the PVM libraries.

www.openmosix.org - openMosix will migrate multiple tasks and allow load 
balancing across a cluster.

To spread ONE task across multiple nodes, you need to write it 
specifically to do this, using eg. PVM or MPI (I prefer the latter - see:

http://www.csm.ornl.gov/pvm/pvm_home.html

Install lam and read the man pages and documentation.

$ rpm -qf /usr/bin/mpirun
   lam-7.1.1-1_FC3

There are sample programs and all...  
   /usr/share/doc/lam-7.1.1/users-guide.ps.gz

Take a look at openmosix. From the little you said, I think it's better 
than the other suggestions.
