frontend bus speed is changed to 800 MHz, so you will see p4 of the 533 Front-End bus and P4 Of the 800 Front-End bus. Their actual external frequencies are only 133 and 200. That is, FSB = CPU external frequency × 4. AMDBased on the same principle, the athlon 64 processor will also support MHz Front-End bus frequency at MHz. However, for AMD athlon XP processors, Dual Data Transmission Technology (DDR, do

For the majority of computer users, CPU cooling is a top priority, whether it is the CPU produced by Intel or AMD, cooling the CPU is very important.
Mainstream processors consume a lot of power and generate high heat. In this way, the CPU cooling requirements are more stringent. With the launch of the more powerful Pentium 4 processor, Intel has updated its requirements for the CPU cooling environment necessary for the system. One of the requirements is to describe the limit value of CPU core t
(key and its value iterator). Also note that the type of the input and output must be consistent with the declaration in the custom reducer.22 orders are sorted first by first field, then the same row in the first field is sorted by the second field, note that the result of the first sort cannot be broken. For exampleInput file20 2150 5150 5250 5350 5460 5160 5360 5260 5660 5770 5860 6170 5470 5570 5670 5770 581 23 45 67 82203 2150 51250 52250 53530
. setgroupingcomparatorclass. As long as the two keys compared by this comparator are the same, they belong to the same group and their values are placed in a value iterator, the iterator uses the first key of all keys in the same group. Finally, it enters the reduce method of CER Cer. The input of the reduce method is all (key and Its Value iterator ). Also note that the input and output types must be consistent with those declared in the Custom CER Cer.

can greatly improve the performance of connecting to and loading shared libraries, generate more optimized code, provide almost perfect API output and prevent symbol collisions. We strongly recommend that you use this option when compiling any shared libraries. See the-fvisibility-inlines-hidden option.

In "file system optimization", the top is the setting item
frequency of the CPU. We need to know that the actual CPU operating frequency should be consistent with the standard operating frequency, but the reason is that the adjustment frequency of the motherboard of each manufacturer is inconsistent, the frequency here has a certain error. If the difference between the two frequencies is too large, the standard operating frequency is 2.40 GHz, and the actual operating frequency is 3.21 GHz, then you will encounter CPU overclocking, if you purchased the

configure scripts use these two environment variables to replace the values in makefile.However, a few configure scripts do not. They must be manually edited.
To set the cflags and cxxflags environment variables, You can execute the following command in bash (or write it into. bashrc to be the default value ):Export cflags = "-O3-March = This is the minimum setting to ensure that it works on almost all platforms.
The "-March" option indicates that binary code is compiled for a specific CPU type
athlon XP 1800 + is equivalent to the frequency of 133mhz external frequency X 11. 5. As long as we increase the frequency to 12.5, the CPU clock speed will become 133mhz × 12. 5 ≈ 1.6 GHz, equivalent to athlon XP 2000 +. If we increase the frequency to 13.5, the CPU clock speed will become 1.8 GHz, and the athlon XP 1800 + overclock will become
CPU, memory, card chip clock frequency increase, the speed of the CD-ROM drive faster, the increase of cooling fan, so the power supply performance requirements are greatly increased. Especially after the introduction of P4, as the current power of the largest desktop CPU processing chips, its power can be up to 60w or more, if the power supply performance is likely to be inadequate. Therefore, on the chassis and power requirements. The P4 has new requirements. We must pay attention to the chas
