Everyone: "..."

"A very useful cipher machine is now completely scrapped."

"The M-209 has long been retired by the U.S. Army, Navy and Air Force."

"But many of our allies in Latin America and the Middle East are still using it. Just last year, it was the M-209 that we assisted the Tibetan Guards."

"No wonder those Tibetans are not beaten at all."

"What's even more frightening is that if the computing speed of the computer continues to increase, it will only be a matter of time before the C52 cipher machine is cracked..."

Colonel John Ram, the highest ranking man in the room, coughed.

"Jack," John Ram called the computer operator's name, "does CDC have a faster computer? How much faster than the CDC 1604? If the military wants to order a computer that is 10 times faster than that computer, can we get what we want?"

"I'm sorry, sir, but I'm just a computer operator at the CDC," Jack said, "a little bit above an intern. But you won't have long to wait for Seymour Clay, the master of CDC 1604." Designer and one of the bosses of our company."

……

At 1 p.m., Seymour Clay entered the Pentagon after being searched and identified.

In 1957, Clay and William Norris partnered to open a computer company called "Control Data Corporation" (CDC), specializing in the development of high-end high-performance computer systems customized for large customers.

The performance of the transistors that were initially available on the market was not stable, but no matter how unstable it was, it was much better than vacuum tubes.Cray used this imitation of the second-generation transistor in China to build a computer, which is basically a transistor version of Remington's UNIVAC 1103 computer.

As for Remington's UNIVAC computer branch, because of the unsuccessful transition to transistors in 1955 and 56 (Remington had built a large factory to produce vacuum tubes and was unwilling to switch), it is now half dead.

The transistorized computer of UNIVAC 1103 was successfully sold after completion. Because it was 55% faster than the C40 computer in China, this computer was sold for 160 million US dollars.

However, Seymour Cray's goal is not limited to this. In the second half of 1959, after the market appeared smaller and more reliable transistors processed by planar technology, Clay immediately came up with a new computer solution CDC1604, which integrated more transistors. , The performance is stronger, and the first one was delivered at the end of February 1960, and the user is the US Army Intelligence Agency.

Now, the customer of Party A urgently summoned Clay to the Pentagon. I don't know if it is a good thing or a bad thing.

"Hello, Colonel Ram." Clay greeted at the door.

"Seymore," Ram said, pulling Kray into the next-door office, "the M-1604 was destroyed in 209. It's incredible. When I graduated from military school and became a company commander, it was the main cipher machine of the US military. Now I want to know , Can CDC produce a computer faster than the 1604?"

Clay: "We have a design for a faster computer. How fast do you want?"

"Ten times faster than the 1604, at least."

Clay: "The calculation speed of CDC1604 is 20 times per second. The CDC3000 series computers we are designing are divided into different configurations and models. The calculation speed is between 50 times and 100 million times."

"That's the two million operations per second computer. With it, the Intelligence Agency will have unprecedented capabilities."

Clay was lost in thought.

"Sorry, although I'm a computer layman," Ram broke the silence, "but if you can, you can increase the number of cabinets without limit."

"Sometimes adding cabinets is not easy..." Clay said perfunctorily, his mind racing.Some plans floated around in my mind, but after careful consideration, these plans were unable to see what they looked like because they were immature.

"Mr. Ram," Clay said, "48-bit word length, increase the frequency, and of course, increase the number of transistors appropriately. It will take CDC about 12 to 18 months to make a computer with 200 million operations. Also, no Do you know if the U.S. Army is willing to pay tens of millions of dollars for this purchase?"

"As long as it can be done, it is a good thing."

Ram doesn't care about finances, he only cares about whether CDC has the ability to make a computer with 200 million operations per second.After getting an affirmative answer, Ram was satisfied.

Several companies led by IBM have been trying their best to fight against the C55 computer in the past, vowing to make a general-purpose computer that has advantages in performance and price over the C55.But the C60 computer once again raised the bar for competition, so these companies are having a hard time.

CDC is targeting the high-end market, specializing in the manufacture of large-scale computers, which has no competitors in North America.

"If we can negotiate some conditions, we can also sell the supercomputer."

The Ministry of Foreign Trade wants to discuss with the United States whether the United States can relax its export control regulations. When consulting opinions, Tang Hua directly mentioned the issue of supercomputers.

The mid-to-long term weather forecast and the three successive explosions of atomic and hydrogen bombs all show that China has high-performance computers that are much faster than general-purpose computers such as C55.

The semiconductor component technology currently mastered by the United States is also sufficient for them to build a "big" transistor computer, which can achieve a calculation speed of more than one million times. "Father of supercomputing" Seymour Clay started to engage in CDC3000 and CDC6000 series supercomputers almost in 1960.

Instead of letting American companies develop computers, it is better for China to sell them directly.

"TC52, TC53, these are three generations of ultra-small transistor supercomputers, or supercomputers. The drawings are not improved at all, and you can sell them directly. But we don't have any old ones to refurbish, so let's build new ones, by the way. Some small functions can be perfected and perfected.”

Ye Jizhuang: "If that's the case, then when I go to negotiate, I need an overview of the performance of the supercomputer to seduce them."

Tang Hua: "Okay, then let Li Qiang quickly come up with a plan for an improved version of TC53, and then disclose the performance of this plan to them."

The solution is of course mainly about the computing speed.In addition to the speed of calculation, one should probably add: This computer can crack the M-209 and C52 cipher machines.

"In the self-defense counterattack against India, air-to-ground guided weapons played a very critical role, absolutely critical."

Three-quarters of the summary meeting of the self-defense counterattack was about the Air Force.As the deputy commander who had been stationed in Kunming during the war, Chang Qiankun talked the most.

"On the Eastern Front, we had three airports at the beginning, and then four airports. In the end, Damxung Airport still did not send planes across Sikkim to fight India. But in any case, the number of planes is still relatively small. The value of guided weapons is to let The Air Force achieved sufficient damage with very few sorties."

"For example, the railway and highway bridges in the Siliguri Corridor, we dispatched 4 planes and dropped 6 bombs before blowing them up. When we fought against US aggression and aided Korea, we had to drop more than 20 bombs on such targets. The level during World War II, that Probably one or two hundred bomber sorties."

"After the bridge was blown up, air-to-surface missiles raided roads and railways, which was impossible before."

“从12月20日全面反击到1月3日左右，我们平均每天出动40到60架次的战斗机、80架次的轰炸机、强击机，数量很少。结果就是完全压制了印度东部的印军地面部队行动。印度在那里的地面部队可是有6万多人，此外还有4万人在通过西里古里走廊往东边拱。”

"Besides the guided weapons, there is the air... the information platform. There are two types of information platforms: those that help us obtain information and those that prevent the other side from obtaining information..."

"Self-defense counterattack, the Air Force's understanding of the performance of fighter jets is the first: fighter jets must have a large range and a large combat radius."

The overall counterattack summary meeting is over, and the Air Force is going to adjust its future aviation equipment route.

"Hey, we introduced the MiG-21 a few years ago. Is this a bit of a mistake?" Liu Yelou said again, "The flight range is only 1400 kilometers, and the combat radius is 600 kilometers! Not enough, not enough. Look at the MiG The -21 is twice the speed of sound, and it flies quite high, so let’s imitate it first. But remember, the combat radius of the next-generation fighter jet is less than 800 kilometers, and the air force does not want it. It is best to reach 1000 kilometers.”

"There is also this missile, missile, can it hang two more..."

"Your comrades in Chengdu are more capable than those in Shenyang," Liu Yelou said. "You developed a JJ-1 completely by yourself, which can not only train pilots, but also do the job of Il-10!"
