SC046 performance improvement, dual-machine cluster
At present, what Nanlin Guiyi needs to solve the most urgent problem is the lack of computing power of Butler's bearing equipment.
Because of this problem, there are many short-term plans and long-term plans in Nan Lin Guiyi's mind, but they cannot be realized. He can only wait for the right time to start the plan again.
However, Nanlin Guiyi has now received $900,000 in hot money and is preparing to invest $200,000 to improve Butler's carrying equipment. According to Nanlin Guiyi's plan, we will directly purchase Intel's latest top server CPU released this year and build 8way top servers.
This level of server is already the top private server!
If you need a more powerful server, you need to deeply customize services and build your own supercomputer. Nanlin Guiyi has insufficient funds and will definitely not be able to build your own supercomputer.
Nanlin Guiyi can purchase two top-level private servers to form a dual-machine cluster. In addition, Nanlin Guiyi has made some mistakes in the calculations. The investment in the dual-machine cluster is not only $200,000, but it will exceed the budget.
Because, Nanlin Guiyi rarely counts storage equipment and UPS uninterrupted power supply equipment. Once Butler is running in a dual-machine cluster, he will definitely need UPS uninterrupted power supply equipment.
Otherwise, what if Butler has a logical error in the event of an unexpected power outage?
Nanlin Guiyi currently has no way to fix Butler's underlying core source code!
In order to avoid Butler's accident, UPS uninterrupted power supply equipment must be owned. Ultra-high-speed storage equipment must also be owned. For example, enterprise-grade solid-state drives are definitely standard.
After these two budgets are invested, at least $50,000 will be added!
Such investment is definitely worth it. Because once Nanlin Guiyi invests two top private servers, Butler's computing resources will be greatly improved.
At present, the computing power controlled by Butler is less than 0.5 tflops. That is, the floating-point computing speed per second is less than 500 billion times. However, the floating-point computing speed of large-scale supercomputers can reach one trillion times at any time!
Just 500 billion times are really not enough to watch!
Because of such weak computing power, Butler's capabilities are severely limited. Once the top private server updated by the Nanlin Relief Program is put into use, Butler will gain more powerful computing resources.
According to the parameters of the Xeon.E7-8870 server CPU, each CPU has ten physical cores, twenty logical threads, and one system contains eight Xeon.E7-8870 server CPUs.
Then, the basic computing power of a system has 3.84 tflops; the peak computing power has reached 4.48 tflops.
The so-called basic computing power and peak computing power are actually because the Xeon.E7-8870 server CPU has different operating frequencies. The lowest basic frequency is 2400MHz and the maximum overclocking frequency is 2800MHz.
Therefore, when the Xeon.E7-8870 server CPU works at different frequencies, different computing resources will be generated.
Nanlin Guiyi is preparing to build two sets of 8way top private servers to form a dual-machine cluster in series. Butler can obtain at least 7tflops.
Why at least 7tflops?
Because when a dual-computer cluster is connected in series, some performance will be lost and the best performance will not be able to be performed. This situation is also very serious in supercomputers.
According to the different design schemes of supercomputers, supporting controls, supercomputer systems, etc., there is a certain gap between the specific performance and design performance.
After Nan Lin Guiyi made up his mind, he yawned. He glanced at the time. It was almost two o'clock in the morning. Nan Lin Guiyi was not going to stay up late to write a program for asynchronous parallel computing scheme.
Early the next morning, Nan Lin Guiyi came to the Kasai Police Station early. He had just sat down in the laboratory on the second floor when Chiba Qikai appeared.
"Officer Nanlin, our team will have a meeting in the second observation room ten minutes later. You can prepare." Qianye Qihai notified Nanlin Guiyi and turned around and left.
Qianye Qihai has returned to its iceberg form, with a cold attitude.
However, Qianye Qihai's attitude made Nan Lin Guiyi very satisfied. Because Qianye Qihai's dislike of her face means that she does not want to "harm" Nan Lin Guiyi.
If Qianye Qihai still gave Nan Lin Guiyi a good face, then Nan Lin Guiyi would think that Qianye Qihai was completely helpless and was willing to fall into depravity!
"Officer Chiba, is there any case?" Nan Lin Guiyi looked at Qianba Qihai's back and asked loudly.
Qianye Qihai did not answer Nan Lin Guiyi, as if he had not heard it, and directly left the physical evidence technology laboratory on the second floor.
Nan Lin Guiyi shrugged slightly, covering up his embarrassment with self-deprecating.
Subsequently, Nanlin Guiyi checked today's physical evidence identification work, and there was only one identification work for analyzing fibers. Although there was only one job, it was very troublesome to identify the fiber components, and what was even more troublesome was to trace the source of the fibers.
For example, the fiber components of a carpet were left at the scene following the footprints of the murderer. The police found the fibers and handed them over to the physical evidence technology laboratory for analysis.
Then, the staff of the Physical Evidence Technology Laboratory must roughly judge the source of the fiber based on the composition of the fiber, so as to confirm the scope of the suspect, etc.
This physical evidence identification work comes from the Komatsugawa Police Station. The unlucky Komatsugawa Police Station has never recruited physical evidence technicians, and always uses the Kasai Police Station and Koiwa Police Station.
These three police stations are in Edogawa and often cooperate with each other. When Minami-rim Reiyi did not join the Kasai Police Station, the physical evidence technicians of Koiwa Police Station were as busy as dogs every day.
Ten minutes later, Nanlin Guiyi put down his work and went downstairs to the observation room No. 2 to attend the search class meeting between Chiba Shikai and Kato Fukuda.
In the observation room No. 2, Chiba Qikai and Fukuda Kato were already waiting for Nanlin Guiyi. Nanlin Guiyi apologized and expressed his apology. Then he asked: "Officer Chiba, what are your team doing?"
Nanlin Guiyi used 'your group' instead of 'our group', meaning to exclude himself and meant not to be integrated into the investigation team of the search class.
Kato Fukuda smiled and said, "Guiyi, you are also a member of our group. Let's discuss how we can continue to investigate the case in Hachimaru warehouse."
Nan Lin Guiyi was shocked, "Does the case in Bamaru Warehouse need to be investigated? Is that not the jurisdiction of the Fukagawa Police Department?"
Qianye Qihai said calmly, "This store has issued an order. The three police stations in Jiangdong District, plus we, must solve the case in Bamaru Warehouse. The time limit is one month!"
"What if it cannot be detected within one month?" Nan Lin Guiyi asked a little 'stupid'.
