is cluster computing possible in two RH8 machines? how?
 

i have 2 PC's with different specs..
but the same RH8 OS..
RH8 2.4.18-14
what should i do to start clustering computing?
is it possible in RH8?
what software should i download?
pls help me.. just trying to use it as my thesis..
thank you very much..
God bless!!

You can successfully cluster 2 machines in RH8, for example 1 master node and one slave machine. Try the following link for details:

have you tried it in redhat? so what software should i install to make it work?

can someone give me a website about clustering in RH8 2.4.18-14 from the start...

Is this what you're looking for?

http://openmosix.sourceforge.net/

kewl! got it! thanks....
im using RH8 kernel 2.4.18-14 (stock RH8)

what should i download:

openMosix-kernel-2.4.18 2.4.18-4
openMosix-kernel-2.4.19 2.4.19-7
openMosix-kernel-2.4.20 2.4.20-3

there is no 2.4.18-14 eh? what should i do now?
will the 2.4.18-4 work to my kernel?
thank you very much

Openmosix looks interesting, camelrider thx for that link. Kublador, you might want to investigate the difference between openmosix and LAM/MPI, they are very different types of clustering.

hmmmmmmmm LAM/MPI? what is that? ;)

Really the question to ask yourself is why you want to cluster your machines. MPI (Message Passing Interface) is a programming tool in the form of libraries that can be used in C/C++ and Fortran (and I've heard there is a version for Java, but that may be PVM, Parallel Virtual Machine, something similar).

When you write your code with MPI, you explicitly tell it how to break up individual tasks between processors. If you don't have code that is written as parallel code, you won't see any advantage from using multiple processors. If you're interested in this, you should check out the MPICH home page, http://www-unix.mcs.anl.gov/mpi/mpich/indexold.html

OpenMosix is very different. With this, it isn't necessary to write special parallel code. When a process is spawned, it is automatically migrated to the processor with the most available resources. Even so, unless you are attempting to solve a large problem, the communication time will most likely dominate any savings you may be gaining in computation time. If you want to play around with this, get the openMosix-kernel-2.4.18 package from the openmosix page. The -14 in your kernel is just saying that RH played around with custom kernels before deciding on that one as their stock kernel.

All in all, unless you're attempting to solve some kind of large problems, you won't see any gain from clustering your machines. It is fun to play around though.

got it.. hmmmmmmm
gotta figure out the /etc/openmosix.map file... grrrr
thanks all =)
God bless!
