To execute a local script on remote machine, you'd do:
Code:
ssh 192.168.1.202 bash < localScript.sh

I am not sure how to pass arguments to localScript.sh this way... maybe someone else can show us.

This should work though:
Code:
./echoInterrupt.sh $period $connections $testcaseid |  ssh 192.168.1.202 bash

This will redirect the output of echoInterrupt.sh and execute it (the output) on the remote machine.
echoInterrupt.sh should look something like this:
Code:
#!/bin/bash  

dtstring=`date +%m%d%l%M |sed 's/ //g'`  
period=$1 
connections=$2 
testcaseid=$3

cat <<EOF #print the commands to be executed

echo "STARTING THE INTERRUPT SCRIPT"

outputfile0="output_period_Core2_${period}_connections_${connections}_${testcaseid}_${dtstring}.txt"

for i in \$(seq 12) ; do   
   grep eth3-TxRx-0 /proc/interrupts >> /home/joydeep/results/interrupt/samesocket/data_cache_misses/$outputfile0 
done 

echo "END OF THE INTERRUPT SCRIPT"
EOF

You have to escape all dollar signs, that you want to pass as literal dollar signs to server, with backslash, as in the '\$(seq 12)' string: you want to pass '$(seq 12)' to the server.

When you run
Code:
./echoInterrupt.sh

it should print all the commands as you want them executed. So for debugging, just do ./echoInterrupt.sh and look at the terminal output to check for syntax errors.

You should not need sudo, since /proc/interrupts is world-readable.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
