Hello, I am trying to run a simple pthread program in gem5 SE x86 mode but it errors out. the program is as below
#include <stdio.h> #include <pthread.h> int result; void *sum(void *threadid) { int a=5; int b=5; result = a+b; printf("result from 1st thread is %d\n",result); pthread_exit(NULL); } void *diff(void *threadid) { int a=5; int b=5; result = a-b; printf("result from 2nd thread is %d\n",result); pthread_exit(NULL); } int main () { pthread_t thread1 , thread2; int rc; int i; rc = pthread_create(&thread1, NULL, sum, (void *)(i)); rc = pthread_create(&thread2, NULL, diff, (void *)(i)); pthread_join(thread1, NULL); pthread_join(thread2, NULL); if (rc) { printf("Error:unable to create thread"); } pthread_exit(NULL); return 0; } And also when I run in SE mode I get the below output. lap318@lap318-HP-Compaq-6730b-KE717AV ~/gem5 $ build/X86/gem5.opt configs/example/se.py -n 4 -c thread gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Nov 28 2017 12:18:46 gem5 started Dec 14 2017 15:46:43 gem5 executing on lap318-HP-Compaq-6730b-KE717AV, pid 2871 command line: build/X86/gem5.opt configs/example/se.py -n 4 -c thread Global frequency set at 1000000000000 ticks per second warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes) 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 0: system.remote_gdb.listener: listening for remote gdb #1 on port 7001 0: system.remote_gdb.listener: listening for remote gdb #2 on port 7002 0: system.remote_gdb.listener: listening for remote gdb #3 on port 7003 **** REAL SIMULATION **** MODIFIED_GEM5 is disabled. info: Entering event queue @ 0.
