    Automatic noautomatic 最大的区别是 Automatic是原子属性的 也是苹果默认的 说的是可以避免一个线程上的对象没设置好的时候进入另一个线程造成混乱,但是Automatic并不是绝对安全的,他只是在setter 和getter方法的时候进行线程保护,并不能完全避免多线程混乱。而且Automatic相对noautomatic非常耗费性能,在iPhone上开发 我通常都选择noautomatic。

    当然选择atomic的时候是有的,如下:
    下面是个 setter时,选择不同修饰符的实例:

    // atomic修饰,不崩溃
    for (int i=0; i< 1000; i++) {
        dispatch_async(dispatch_get_global_queue(0, 0), ^{
            self.obj_atomic = [NSObject new];
        });
    }
    // nonatomic修饰,会崩溃
    for (int i=0; i< 1000; i++) {
        dispatch_async(dispatch_get_global_queue(0, 0), ^{
            self.obj_nonatomic = [NSObject new];
        });
    }
    

    以上就是atomic在setter方法的时候对相应对象的new进行了保护,避免错乱。

    The Automatic Segment Advisor is an automated maintenance task that is configured to run during all maintenance windows.

    The Automatic Segment Advisor does not analyze every database object. Instead, it examines database statistics, samples segment data, and then selects the following objects to analyze:
    分析的三中对象:太积极的segment,超出规定(临界值)的tablespace,增长太快的segments。

    Tablespaces that have exceeded a critical or warning space threshold
    Segments that have the most activity
    Segments that have the highest growth rate

    In addition, the Automatic Segment Advisor evaluates tables that are at least 10MB and that have at least three indexes to determine the amount of space saved if the tables are compressed with the advanced row compression method.

    此外,自动段Advisor会评估至少10MB且至少有三个索引的表,以确定在使用高级行压缩方法压缩表时节省的空间量。

    If an object is selected for analysis but the maintenance window expires before the Segment Advisor can process the object, the object is included in the next Automatic Segment Advisor run.

    如果选择对象进行分析但维护窗口在Segment Advisor处理对象之前到期,则该对象将包含在下一个Automatic Segment Advisor运行中。也就是说,选择对象会分析的,不是在这个,就是在下一个。

    You cannot change the set of tablespaces and segments that the Automatic Segment Advisor selects for analysis. You can, however, enable or disable the Automatic Segment Advisor task, change the times during which the Automatic Segment Advisor is scheduled to run, or adjust automated maintenance task system resource utilization
    无法更改Automatic Segment Advisor选择用于分析的表空间和段的集合。 但是,您可以启用或禁用Automatic Segment Advisor 任务,更改Automatic Segment Advisor 计划运行的时间,或调整自动维护任务系统资源利用率。
    只可以选择用或不用,什么时候用,和如何利用资源,至于我怎么干,你管不着。

  • Automatic Memory Dump

    https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/automatic-memory-dump

    An Automatic Memory Dump contains the same information as a Kernel Memory Dump. The difference between the two is not in the dump file itself, but in the way that Windows sets the size of the system paging file.

    If the system paging file size is set to System managed size, and the kernel-mode crash dump is set to Automatic Memory Dump, then Windows can set the size of the paging file to less than the size of RAM. In this case, Windows sets the size of the paging file large enough to ensure that a kernel memory dump can be captured most of the time.

    If the computer crashes and the paging file is not large enough to capture a kernel memory dump, Windows increases the size of the paging file to at least the size of RAM. The time of this event is recorded here in the Registry:

    HKLM\SYSTEM\CurrentControlSet\Control\CrashControl\LastCrashTime

    The increased paging file size stays in place for 4 weeks and then returns to the smaller size. If you want to return to the smaller paging file before 4 weeks, you can delete the Registry entry.

    To see the paging file settings, go to Control Panel > System and Security > System > Advanced system settings. Under Performance, click Settings. On the Advanced tab, under Virtual memory, click Change. In the Virtual Memory dialog box, you can see the paging file settings.

    screen shot of the virtual memory dialog box.

    The Automatic Memory Dump file is written to %SystemRoot%\Memory.dmp by default.

    The Automatic Memory Dump is available in Windows 8 and later.

    本文展现了module,task和变量为automatic和非automatic时的仿真结果,用于分析automatic的功能与作用范围。

    automatic 仿真测试

    1、子程序均为静态存储的情况

    module test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=0;j<3;j++) begin
    			fork
    				distest(j);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,三次打印,k的值都为3。因为system verilog中,module和program块中子程序的存储方式在缺省情况下使用的是静态存储。

    0:j=3;
    100: k = 3;
    100: k = 3;
    100: k = 3;
    

    2、在静态存储子程序中加入automatic的中间变量

    module test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=0;j<3;j++) begin
    			fork
    				automatic int m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,中间值m的打印为2,1,0,但是distest打印的k值均为0。

    0:j=3,m=2;
    0:j=3,m=1;
    0:j=3,m=0;
    0:j=3;
    100: k = 0;
    100: k = 0;
    100: k = 0;
    

    修改j的取值范围为1-3,for(j=1;j<4;j++),仿真结果如下,但是distest打印的k值均为1,结合上面的仿真结果,推测因为distest是静态存储的,所以仿真时以第一次配置生效,每次执行时,从静态存储区拷贝出来的取值地址为m=1的地址

    0:j=4,m=3;
    0:j=4,m=2;
    0:j=4,m=1;
    0:j=4;
    100: k = 1;
    100: k = 1;
    100: k = 1;
    

    3、修改module test为动态存储

    a、修改module test为动态存储,去掉中间存储变量m

    module automatic test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				//automatic int m=j;
    				distest(j);
    				//$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,k的三个打印值均为1。

    0:j=1;
    100: k = 1;
    100: k = 1;
    100: k = 1;
    

    b、修改module test为动态存储,加入中间存储变量m

    module automatic test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				int m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task  distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,k的打印值为2,3,4,与期望相符。

    0:j=1,m=2;
    0:j=1,m=3;
    0:j=1,m=4;
    0:j=1;
    100 :k = 2;
    100: k = 3;
    100: k = 4;
    

    c、修改module test为动态存储,加入中间存储变量m,默认动态存储,声明与赋值分开

    module automatic test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				int m;
    				m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task  distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,k的三个打印值均为1。

    0:j=1;
    100: k = 1;
    100: k = 1;
    100: k = 1;
    

    4、修改distest task为动态存储

    a、去掉中间存储变量m,或m为静态存储

    module  test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				//automatic int m=j;
    				distest(j);
    				//$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task automatic distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下:

    0:j=1;
    100: k = 1;
    100: k = 1;
    100: k = 1;
    

    加入m为静态存储,int m=j,仿真结果如下,这个结果原因是m是静态分配的,仿真一开始就有了初值,初值为0.

    0:j=1,m=0;
    0:j=1,m=0;
    0:j=1,m=0;
    0:j=1;
    100 :k = 0;
    100: k = 0;
    100: k = 0;
    

    b、m为静态存储,但是声明和赋值分开

    module  test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				int m;
    				m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task automatic distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,

    0:j=1,m=1;
    0:j=1,m=1;
    0:j=1,m=1;
    0:j=1;
    100 :k = 1;
    100: k = 1;
    100: k = 1;
    

    c、m为动态存储,但是声明和赋值分开

    module  test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				automatic int m;
    				m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task automatic distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,

    0:j=1,m=1;
    0:j=1,m=1;
    0:j=1,m=1;
    0:j=1;
    100 :k = 1;
    100: k = 1;
    100: k = 1;
    

    d、m为动态存储,但是声明和赋值在一起

    module  test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				automatic int m=j;
    				//m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task automatic distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,

    0:j=1,m=2;
    0:j=1,m=3;
    0:j=1,m=4;
    0:j=1;
    100 :k = 2;
    100: k = 3;
    100: k = 4;
    

    5、修改aotumatic_tset task为动态存储

    a、中间变量m默认为动态存储,声明和赋值在一起

    module  test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				int m=j;
    				//m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,

    0:j=1,m=2;
    0:j=1,m=3;
    0:j=1,m=4;
    0:j=1;
    100 :k = 4;
    100: k = 4;
    100: k = 4;
    

    b、中间变量m默认为动态存储,声明和赋值分开

    module  test;
    
    	initial begin
    		automatic_test;
    	end
    	
    	task automatic automatic_test;
    		int j;
    		for(j=4;j>1;j--) begin
    			fork
    				int m;
    				m=j;
    				distest(m);
    				$display($time,": j=%0d, m=%0d",j,m);
    			join_none
    		end
    		#0 $display($time,": j=%0d",j);
    		#1000;
    	endtask:automatic_test
    	
    	task distest(int k);
    		#100;
    		$display($time,": k = %0d",k);
    	endtask:distest
    endmodule
    

    仿真结果如下,

    0:j=1,m=1;
    0:j=1,m=1;
    0:j=1,m=1;
    0:j=1;
    100 :k = 1;
    100: k = 1;
    100: k = 1;
