The following problem concerns the way virtual addresses are translated into physical addresses. Thememory is byte addressable. • Memory accesses are to 1-byte words (not 4-byte words). • Virtual addresses are 16 bits wide. • Physical addresses are 13 bits wide. •The page size is 512 bytes. • The TLB is 8-way set associative with 16 total entries. • The cache is 2-way set associative, with a 4 byte line size and 16 total lines. In the following tables, all numbers are given in hexadecimal. The contents of the TLB, the page table for the first 32 pages, and the cache are as follows: TLB Page Table 2-way Set Associative Cache Index Tag PPN Valid VPN PPN Valid VPN PPN Valid Index Tag Valid Byte 0 Byte 1 Byte 2 Byte 3 Tag Valid Byte 0 Byte 1 Byte 2 Byte 3 0 09 4 1 00 6 1 10 0 1 0 19 1 99 11 23 11 00 0 99 11 23 11 12 2 1 01 5 0 11 5 0 1 15 0 4F 22 EC 11 2F 1 55 59 OB 41 10 0 1 02 3 1 12 2 1 2 1B 1 00 02 04 08 OB 1 01 03 05 07 08 5 03 4 1 13 4 0 3 06 0 84 06 B2 9C 12 0 84 06 B2 9C 05 7 1 04…
Part II (8 points) int counter = 0; void handler(int sig) { counter++; } int main() { int i; signal(SIGCHLD, handler); for (i = 0; i < 5; i ++){ if (fork() == 0){ } } exit(0); /* wait for all children to die */ while (wait(NULL) != -1); printf("counter = %d\n", counter); return 0; } A. Does the program output the same value of counter every time we run it? Yes No B. If the answer to A is Yes, indicate the value of the counter variable. Otherwise, list all possible values of the counter variable. Answer: counter =
A useful helper function for opening a socket connection to a server was introduced in the course: int open_clientfd(char *hostname, int port) { int clientfd; struct hostent *hp; struct sockaddr_in serveraddr; if ((clientfd = socket(AF_INET, SOCK_STREAM, 0)) h_addr_list[0], (char *)&serveraddr.sin_addr.s_addr, hp->h_length); serveraddr.sin_port = htons(port); /* Establish a connection with the server */ if (connect(clientfd, (SA *) &serveraddr, sizeof(serveraddr)) < 0) return -1; return clientfd; } The problem with this function is that it is not thread safe: it uses function gethostbyname, which returns a pointer to a static variable. On the following page, reimplement open_clientfd in a thread safe way using the lock-and-copy technique. (Note 1: that the new function will take an additional input: a semaphore that will control access to the critical section so only one thread at a time can call gethostbyname and read the result stored in a static variable. Note 2: a call to malloc is…
