He empezado a leer Sistemas Operativos: Three Easy Pieces, cuando ejecuté el ejemplo 2.1 en mi Macbook Air M1 con 4 instancias en paralelo se generaron 4 procesos únicos, pero luego mi portátil se estrelló después de 2-3 segundos. Por favor, encontrar los pasos para replicar a continuación:
simple-example.c
#include <stdio.h>
#include <stdlib.h>
#include <sys/time.h>
#include <assert.h>
#include "common.h"
int
main(int argc, char *argv[]){
if (argc != 2) {
fprintf(stderr, "usage: cpu <string>\n"); exit(1);
}
char *str = argv[1];
while (1) {
Spin(1);
printf("%s\n", str);
}
return 0; }[common.h][1]
#ifndef __common_h__
#define __common_h__
#include <sys/time.h>
#include <sys/stat.h>
#include <assert.h>
double GetTime() {
struct timeval t;
int rc = gettimeofday(&t, NULL);
assert(rc == 0);
return (double) t.tv_sec + (double) t.tv_usec/1e6;
}
void Spin(int howlong) {
double t = GetTime();
while ((GetTime() - t) < (double) howlong)
; // do nothing in loop
}
#endif // __common_h__El programa anterior tal y como se explica en el libro:
La figura 2.1 muestra nuestro primer programa. No hace mucho. De hecho, todo lo que hace es llamar a Spin(), una función que comprueba repetidamente el tiempo y regresa una vez que se ha ejecutado durante un segundo. Entonces, imprime la cadena que el usuario pasó en la línea de comandos, y repite, para siempre.
He copiado common.h del archivo enlazado de github
Compilar:
~ gcc -v
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.5 (clang-1205.0.22.11)
Target: arm64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
gcc -o cpu simple-example.c -WallLa ejecución de una sola instancia del proceso con una cadena funciona bien:
./cpu "A"La ejecución de varias instancias bloquea el portátil:
./cpu A & ; ./cpu B & ; ./cpu C & ; ./cpu D &Esto genera 4 procesos y comienza a imprimir las cadenas A C B D en orden aleatorio, pero luego una luz púrpura parpadeó y el portátil murió.

¿Es un problema de código o de M1 SOC?
¿Cómo le explico esto a Apple para que me sustituya? Compré este portátil el 4 de agosto sin apple care
Actualización: @DarkDust sugirió matar a redis e intentarlo, sigue fallando.
