According to the code list 1-5 provided in the book, you can control the CPU usage of multi-core processors.
However, when getcputickcount is used for timing, the following formula may have a small problem:
Here, according to the name defined by the millisec variable, the calculation result of the formula below is millimeter ms,
(Double) t_end-(double) t_begin)/(double) info. currentmhz
The unit of the calculated result is second.Because

things you can do because a worker process can send messages to the main process, so that each worker process can report its own state, such as memory usage. This allows the main process to detect which worker processes have become unstable, which processes are not frozen, or blocked.varCluster = require (' cluster '));varHTTP = require (' http ');varNumcpus = require (' OS ').

Linux kernel author Linus Torvalds a patch in Linux 3.8 that incorporates Ingo Molnar, formally terminating support for i386 processors. After merging the patch, the 386 DX33 ancient system from 1991 years will not start under modern Linux kernel. Linus commented that he was not a sentimental person, and he was glad to finally get rid of it.
The i386 processor, a 32-bit microprocessor launched by Intel in 1985, has 275,000 transistors and is widely

Intel processors implement 4 privilege levels Ring0-ring3
Windows uses two
The implementation of the permission is the range of the value of the address, and the value of several registers
In ring3 work, CS, DS, SS registers are always values 8, 10, and 10 respectively. This allows the system code to monitor the value of the segment registers. Select Sub 1b and 23 for addressing when the kernel (driver, system code) is working. Select 30 and 3b poi

---- Delphi is a powerful visual program development tool. While developing WINDOWS applications using Delphi, Delphi provides many properties and events for each visualization component ), however,
In Delphi, an event is actually a specialized attribute, and it is a procedure pointer. To add an event, you must first describe a class to point to the event
The pointer of a program. The pointer is used to process the event once it occurs.
In most browsers, when an event processor is triggered, the class instance named event is passed into the processor as the first parameter. However, ie, which has been dominant, acts in its own way and saves the event instance to a global attribute
