To distribute among several Linux nodes, you can build a cluster, as Neo suggested.

OR you can use ssh/rsh to distribute run the jobs on the other hosts. First, make a file containing the hostnames of your cluster. If a host has 2 CPUs, have the hostname entry twice. If it has 4 cores, have 4 entries of that hostname.

From here you can go in different directions, but ultimately, you run one rsh/ssh process her line in this hosts file.
Hi Neo and otheus,

Thanks for ur valuable replies....

I am currently exploring all options suggested here....


Thanks...

NAME
rcsmerge - merge RCS revisions SYNOPSIS
rev2] file DESCRIPTION
incorporates the changes between rev1 and rev2 of an RCS file into the corresponding working file. If is given, the result is printed on the standard output; otherwise the result overwrites the working file. A file name ending in is an RCS file name; otherwise it is a working file name. derives the working file name from the RCS file name and vice versa, as explained in rcsintro(5). A pair consisting of both an RCS and a working file name can also be specified. rev1 cannot be omitted. If rev2 is omitted, the latest revision on the trunk is assumed. Both rev1 and rev2 can be given numerically or symbolically. prints a warning if there are overlaps, and delimits the overlapping regions as explained for the option of co(1). The command is useful for incorporating changes into a checked-out revision. EXAMPLES
Suppose you have released revision 2.8 of Assume furthermore that you just completed revision 3.4 when you receive updates to release 2.8 from someone else. To combine the updates to 2.8 and your changes between 2.8 and 3.4, put the updates to 2.8 into file and execute: Then examine Alternatively, if you want to save the updates to 2.8 in the RCS file, check them in as revision 2.8.1.1 and execute As another example, the following command undoes the changes between revision 2.4 and 2.8 in your currently checked out revision in Note the order of the arguments, and that is overwritten.
