How can we optimize your system? The following is a simple and small method, but the optimization and adjustment of a system is far more than that. The performance needs to be adjusted according to actual needs. There is no way to meet all system requirements.
1. Check your gcc version:Note that your gcc version must be later than 3.0.
# Gcc -- version
2. obtain your cpu model:
Cat/proc/cpuinfo
3. Create the make. conf file under/etc/and write different contents according to the cpu model.

In the past few days, I have helped students read their laptops and learned a lot about them. At the same time, I am deeply impressed by the differences between the notebook market and the desktop market, not to mention the complexity and confusion of various brand series and models (just an IBM t42 series has dozens of models, each model is followed by three numbers/letters, so that outsiders do not know the so-called), just say that the commonplace of the company,
the hardware based on the BIOS (basic input and output system) and enters the operating system to perform the function of supporting the system platform.

Summary: This article describes code optimization in Visual C++.net 2003. In addition, some readers may not know much about the optimization of Vc.net 2002, so we will briefly introduce the whole process optimization (Whole program Optimization). Finally, we use some examples to fully show the optimization performance of vc.net and discuss it.
Objective
People in the use of a new programming tool always feel lack of self-confidence, this article tries to let you VC code optimization has a more

The white cable is most likely a 1Gbps Ethernet connection, which is used for system management. In the photos, we don't see how Google connects the management network to the TPU2 circuit board. However, based on the line alignment of the white cable, we can assume that Google connects the processing board to the management network from the back of the rack. Perhaps, the processing board will manage the TPU2 board through the OPA Connection and evaluate the health status of t

At first glance, I was shocked. I haven't looked at it for a long time. The intelcpu came out with so many models. It was a bit confusing. Fortunately, I had a network and checked it and sorted it out.
The current market's CPUs include T series, P series, E Series, I3, I5, and i7.
The T series is Intel dual-core and mainly used in laptops. Including Pentium dual-core and core dual-core, less than
Simple Guide to MySQL optimization (1. optimizing MySQL during compilation
If you distribute and install MySQL from the source code, note that the compilation process will have an important impact on the future target program. different compilation methods may obtain similar target files, however, the performance may vary greatly. Therefore, when compiling and installing MySQL, you must carefully select the most likely compilation option based on your application type. This custom MySQL can p
early Pentium 4 series processors, with a pin number of 478 pins. The Pentium 4 processor area of Socket 478 is small and the pins are very tightly arranged. Intel Corporation's Pentium 4 series and P4 Celeron series all use this interface, the current CPU has been phased out of the market.
However, Intel launched a new socket 478 interface in early 2006, which

If the Second Pipeline mode above can increase the processor clock speed to 2 GHz, we should be able to achieve twice the performance of the original processor-if the pipeline remains fully loaded.
However, this is not the case. Any internal CPU pipeline may encounter errors during pre-reading. Once an error occurs, the command must be re-executed from the first level pi
