Thank you, Don Cragun for replying.
The problem here is - process X does not get initiated by the user, it is started from within another master process which is the main design software (installed in our company's server, so I don't have much access to that other than launching it and working on it) I am using in my system. Now, I don't know on what basis process X is started. So, everyday morning, I used to kill process X and continue with my work. If am in front of my workstation, I can manually check the status of process X and kill it whenever necessary. However, if it starts overnight then it slows don the progress of other simulations being run in the main software. So, I wanted to have a local work around to this problem so that what I am doing manually (when I am in front of the workstation) can be done automatically. And I don't have to bother about it forever

What shell are you using?
When you are in front of your workstation and manually kill process X, please show us exactly what commands do you type into your shell to kill process X (in CODE tags). If you want a script to replace what you're doing manually, it is always great to actually know what you do manually! Show us the output produced by each step. Tell us what you use from each step as input to the next step.
Do you really have to use kill -9 PID? Doesn't kill PID work?

settaskid
settaskid(2) System Calls settaskid(2) NAME
settaskid, gettaskid, getprojid - set or get task or project IDs SYNOPSIS
#include <sys/types.h> #include <sys/task.h> #include <unistd.h> taskid_t settaskid(projid_t project, int flags); taskid_t gettaskid(void); #include <sys/types.h> #include <sys/task.h> #include <unistd.h> #include <project.h> projid_t getprojid(void); DESCRIPTION
The settaskid() function makes a request of the system to assign a new task ID to the calling process, changing the associated project ID to that specified. The calling process must have sufficient privileges to perform this operation. The flags argument should be either TASK_NORMAL for a regular task, or TASK_FINAL, which disallows subsequent settaskid() calls by the created task. The gettaskid() function returns the task ID of the calling process. The getprojid() function returns the project ID of the calling process. RETURN VALUES
Upon successful completion, these functions return the appropriate task or project ID. Otherwise, -1 is returned and errno is set to indi- cate the error. ERRORS
The settaskid() function will fail if: EACCES The invoking task was created with the TASK_FINAL flag. EAGAIN A resource control limiting the number of tasks or LWPs in the current project or zone has been exceeded. EINVAL The given project ID is not within the valid project ID range. EPERM The {PRIV_PROC_TASKID} privilege is not asserted in the effective set of the calling process. ATTRIBUTES
