（尽管OpenMP可以方便地对for循环进行并行化，但并不是所有的for循环都可以进行并行化。以下几种情况不能进行并行化：
for循环中的循环变量必须是有符号整形。例如，for (unsigned int i = 0; i < 10; ++i){}会编译不通过；
for循环中比较操作符必须是<, <=, >, >=。例如for (int i = 0; i ！= 10; ++i){}会编译不通过；
for循环中的第三个表达式，必须是整数的加减，并且加减的值必须是一个循环不变量。例如for (int i = 0; i != 10; i = i + 1){}会编译不通过；感觉只能++i; i++; –i; 或i–；
如果for循环中的比较操作为<或<=，那么循环变量只能增加；反之亦然。例如for (int i = 0; i != 10; –i)会编译不通过；
循环必须是单入口、单出口，也就是说循环内部不允许能够达到循环以外的跳转语句，exit除外。异常的处理也必须在循环体内处理。例如：若循环体内的break或goto会跳转到循环体外，那么会编译不通过。 ）
