The last article on how to use LoadRunner monitor Linux performance indicators, but the CPU on a few indicators are not clear, the following detailed said.
CPU Utilization good understanding, that is, CPU utilization, more than 75% is higher (also has the argument is 80% or higher). In addition to this indicator, but also in combination with the load average and
Pay attention to the computer hardware description of the person, basically know that the cup is running speed, this speed is actually representative of the CPU in the normal working state of the speed. As with the car engine, because the manufacturer to protect the quality of the CPU, so the speed is not its fastest frequency, and more than the limit frequency is much lower, so the
i7 positioning high-end, in contrast, or i5 processor better.
As for the specific model of the I5 series, it is recommended to use the Intel Daicouri i5-6400, i5-6500, i5-6600, i5-6600k processor in the first instance, in addition, the installed users can also choose a i7 Dai Zhiqiang of six E3 processors, such as E3 1230v5 bulk, Main high cost performance.
Of course, here can also choose AMD processor, if you want to consider, you can choose
some good overclock and some bad overclock messages. There are also some posts on the Internet to teach you how to pick out super CPU, the online prawns are just reading the dump code on the amd cpu. They know that the processes used by those products are the latest, and those CPUs are the most resistant to high temperature, today, we will bring you the most comprehensive amd
Generally speaking, the bulk of the CPU does not have a radiator and the package is a year, and the boxed CPU is with the radiator of the quality package is three years. From a technical point of view, there is no essential difference between bulk and boxed CPUs, at least in terms of quality. Theoretically, there is no gap in performance, stability, and overclocking potential between boxed and bulk products
Socket fm2+ Interfacethe socket fm2+ is a successor to the socket FM2 and can be partially compatible with the socket FM2 processor. Socket fm2+ is the latest AMD Desktop platform CPU socket, the third generation Apu, compared to the second generation FM2, only two more pin support, PCIe 3.0 and unified addressable space, fm2+ motherboard October 2013 has been listed. Socket FM2 Interfacesocket FM2 is the CPU
Q: Can the CPU fan be universal, if not general how to choose the CPU fan? (I use the Sai Yang 2.4G)
For:
The CPU fan is generic and is not generic. Common in the market is not universal fan, cheaper, universal fan belongs to high-end products, is recommended by DIY enthusiasts, the price is more expensive.1, if you just want to install a fan 2.4G, then go to t

would have been a program that was cured inside the chip, then developed to be locally programmable and finally fully programmable. In other words, the GPU is developing in the direction of general processing while increasing the throughput being processed.
2 build OpenCL environment under Linux workstations
High-Performance lab, the OPENCL environment for Linux has been configured on both workstations.
The hardware and operating system configurations are as follows:

of the DEP protection function, in addition to upgrading the system to SP2, your CPU must also support the DEP technology. Currently, common 32-bit processors (such as P4 Northwood) do not support NX. The CPUs supporting this technology mainly include AMD's 64-bit processors (Athlon 64 and AMD Opteron ), and Intel's Apsara series CPU and J series P4 Prescott. It is said that companies such as nVIDIA, VIA,

CPU Cache
Most CPUs only have Level 1 cache and level 2 cache, and some have Level 3 cache.The cache memory is the temporary memory between the CPU and memory. It has a smaller capacity than the memory but is faster than the memory. The data in the cache is a small part of the memory, but this small part is about to be accessed by the CPU in a short time.
