Not sure what kind of script and/or shell you're using, but in Bash, you can use an infinite while loop and add a sleep line at the end of the loop:
while [ 1 ]
do
your commands here
sleep 900
done
The commands will execute and then sleep for 15 minutes, then restart the loop.
Hope this helps.

pthread_attr_setschedparam
PTHREAD_ATTR_SETSCHEDPARAM(3) Linux Programmer's Manual PTHREAD_ATTR_SETSCHEDPARAM(3)
NAME
pthread_attr_setschedparam, pthread_attr_getschedparam - set/get scheduling parameter attributes in thread attributes object
SYNOPSIS
#include <pthread.h>
int pthread_attr_setschedparam(pthread_attr_t *attr,
const struct sched_param *param);
int pthread_attr_getschedparam(const pthread_attr_t *attr,
struct sched_param *param);
Compile and link with -pthread.
DESCRIPTION
The pthread_attr_setschedparam() function sets the scheduling parameter attributes of the thread attributes object referred to by attr to
the values specified in the buffer pointed to by param. These attributes determine the scheduling parameters of a thread created using the
thread attributes object attr.
The pthread_attr_getschedparam() returns the scheduling parameter attributes of the thread attributes object attr in the buffer pointed to
by param.
Scheduling parameters are maintained in the following structure:
struct sched_param {
int sched_priority; /* Scheduling priority */
};
As can be seen, only one scheduling parameter is supported. For details of the permitted ranges for scheduling priorities in each schedul-
ing policy, see sched(7).
In order for the parameter setting made by pthread_attr_setschedparam() to have effect when calling pthread_create(3), the caller must use
pthread_attr_setinheritsched(3) to set the inherit-scheduler attribute of the attributes object attr to PTHREAD_EXPLICIT_SCHED.
RETURN VALUE
On success, these functions return 0; on error, they return a nonzero error number.
ERRORS
pthread_attr_setschedparam() can fail with the following error:
EINVAL The priority specified in param does not make sense for the current scheduling policy of attr.
POSIX.1 also documents an ENOTSUP error for pthread_attr_setschedparam(). This value is never returned on Linux (but portable and future-
proof applications should nevertheless handle this error return value).
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
