More information regarding Parallel Execution
Hi quirkasaurus,
Thanks for ur reply..
As per ur reply i would like to give some more details about my problem,
I have 500 different set of arguments in a file(say list.txt). These arguments i need to pass to an executable (or an application; say "./applictn.out") which wil run and does the job taking each arguments. That means i will get 500 sets of outputs on executing whole system.
If I execute this using script serially(means one after other) execution wil take more time. so within a system i can execute this in parallel (i.e making them as background process) using xargs. Like
Syntax:xargs <utility> <arguments>
Given: xargs ./applictn.out list.txt..
This wil be executed in parallel on single system..
Now my problem is if i want to execute these sets(set of 500 arguments) on different linux systems, which should run in parallel. So that i should get output at lower amount of time.
parallelism i mean to say is, if mahine1 should take say 150 sets and start processing..
Machine 2 should take say 200 sets and starts processing..
machine 3 should take remaining in sets and should start working on it..
All machines should work in parallel...
Thanks..

do you have the arguments already somewhere or
will you generate them?
should the jobs run in series once on their individual machine?
or can they run concurrently with a maximum threshold?
is this just for benchmarking? or is this going to be a permanent run and
everything should take about the same time?
i'm thinking . . . . just create all the command lines....
dump them all into a file...
then have another script, read this file,
divide them equally into scripts for each machine....
rcp these scripts to the respective machines,
and kick 'em off.

rcsmerge
rcsmerge(1) General Commands Manual rcsmerge(1)
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.
