How to write a regular expression that matches the following string:
Each project to be matched ends with a space.
Server_model = ProLiant DL360 G5; server_cpu_model = Intel (R) Xeon (R) CPU E5405 @ 2.00 GHz; cpu = 21 mhz; 1; 3; 5; 8

① eight years ago, 45 nm CPU?
First look at the CPU, the old Xeon Quad-core E5405, what is this concept? Eight or nine years ago, 45nm era of high-end products (last year is already 14nm era, good or bad!). The backward architecture, the weak single core performance of the current mains

popular 2U dual-rack server with a high market share in the small and medium enterprises market. The Dell PE2950 adopts a modular design to facilitate upgrade management and maintenance and flexible configuration. Users can customize procurement as needed. Its rich management functions provide convenience for small and medium-sized enterprises with insufficient IT experience. At present, a Dell PE2950 with a single intel quad-core Xeon 5405 processor is priced at only 9500 yuan, and a keyboard
suitable for hosting while ensuring a spacious internal space, it is good for both heat dissipation and expansion, but now the price of this machine is also relaxed, and now it is only 13500 yuan. If you are interested, you can consider it.
HP ProLiant DL380 G5 (470064-635) uses a dual-circuit design. The motherboard has two CPU slots, but the standard quantity is one. It uses a quad-core Intel Xeon E5405 processor, which uses a 45nm process, the pe
During the memcpy operation, although it is a memory operation, it still consumes a little CPU. Today we tested the efficiency of executing memcpy in a single thread. The result is for configuring the work thread in TCP epoll.
The quantity has guiding significance. The following example shows how to execute memcpy quickly based on 8 K memory. One thread can copy 500 m in about 1 second. If the server bandwidth or network card reach the upper limit of 1 GB, the network I/O work thread can be op

In fact, we can use a pure Python language to implement the WEB. After implementation, we still need to test this function. Here, we will use some methods to test Python WEB implementation. I hope you can take this as a learning reference object.

It does not affect other users to put "/apps/myapp1/latest/bin/" in your $ PATH. /Apps/myapp1/env/is the script and file used to modify the user environment. I chose the GNU/Linux release for hardware and software. I have installed a server with an Intel (R) Xeon (R) E5405 @ 2.00GHz quad core processor. This is why I use the "-np 4" command.

flaw in NUMA. There are several ways to turn off the CPU NUMA: 1) in the Biso configuration; 2) Numactl--interleave=all [Email protected] ~]# Numactl--interleave=all Interleave=all is actually the memory in each node of the NUMA architecture and re-virtual into a shared memory for allocation, but unlike SMP, because there are inter-connect between every two node, This avoids the drawbacks of SMP architecture bus contention.
