Hi,
I have created 4 threads in my linux system using
pthread_create() API.
Each thread does nothing but just sleeps using
sleep().
e.g.
int main()
{
pthread_create(thread1);
pthread_create(thread2);
pthread_create(thread3);
pthread_create(thread4);
while(1) {
};
return 0;
}
Here are the results of "top".
Before running above program,
total process = 35
sleeping process = 34,
running = 1.
After running about program,
total process = 41
sleeping process = 39,
running = 2.
Can somebody give me justification for this addition
of one more process for this?
We know that threads = processes = task_struct in
kernel when it comes to scheduling them.
But why there is an overhead of one more
thread/process?
Regards,
Parav Pandit
