Complete this general code with accurate code logic
Implement the commented out functions and help how CPU affinity is achieved
#include
// Define the structure for a node in the linked list typedef struct Node { int data; struct Node* next; } Node;
// Global variable Node* head = NULL;
// Function to add roll numbers to a list in parallel void* addRollNumbersToListParallel(void* arg) { // Your implementation for adding roll numbers to a list in parallel return NULL; // Placeholder return value }
// Function to perform merge sort in parallel void* mergeSortParallel(void* arg) { // Your implementation for performing merge sort in parallel return NULL; // Placeholder return value }
// Function to set CPU affinity for a thread void setAffinity(pthread_t thread, int coreId) { cpu_set_t cpuset; // Declare cpu_set_t variable CPU_ZERO(&cpuset); // Initialize cpu_set_t variable CPU_SET(coreId, &cpuset); // Set the specified CPU core if (pthread_setaffinity_np(thread, sizeof(cpu_set_t), &cpuset) != 0) { perror("pthread_setaffinity_np"); exit(EXIT_FAILURE); } }
int main() { // Example usage of the functions pthread_t tid1, tid2; // Example thread IDs
// Example usage: setting CPU affinity for threads setAffinity(tid1, 0); // Example: assign thread tid1 to CPU core 0 setAffinity(tid2, 1); // Example: assign thread tid2 to CPU core 1
return 0; }
