[251] "MESM" supercomputer

As the first batch of small electron tubes supplied by China to the Soviet Union, the first batch of 100,000 vacuum tubes of various types has gone through a long journey of nearly a month, and as the freight train was transported to Moscow, this batch of vacuum electrons includes diodes, triodes, fourth-stage tubes, fifth-stage tubes, and sixth-stage tubes. As for the multi-stage pipes and composite pipes above level 7, Xiaoqiang felt that it was a little too dark, so in order not to irritate the big brother of the Soviet Union, he did not list them in the export catalog for the time being.

Among the 100,000 vacuum tubes of various models, except for most of the small diodes and transistors, the rest are priced higher than $30, and the reason why so many new varieties have been added to the original small diodes and transistors is because Xiaoqiang has decided that the Soviet Union will definitely accept all the goods.

After seeing so many varieties arrived, Raminov, an electronics expert sent by the USSR Academy of Sciences for acceptance, was very surprised, and he immediately asked Wang Jiaxiang, the Chinese ambassador who came from the embassy to the station to hand over the escort: "Mr. Ambassador, it seems that many of these products are not in our pre-determined product catalog. ”

Ambassador Wang Jiaxiang said: "We have recently obtained a batch of tube products embargoed by the West on the socialist camp, and after we obtained these products through secret channels, we immediately remembered our great ally, the Soviet Union, the big brother of socialism. The Central Committee resolutely decided to first provide these products to the Soviet Union at cost price. ”

Raminov was surprised to pick up a voltage amplification tube, thyristor tube, ignition tube, rectifier tube, oscillation tube, detector, voltage regulator tube and looked at the jishu index manual, the more he looked at it, the more surprised he became, the more excited he looked, trembling and almost jumping up, and said unabashedly: "Great! That's great! Here are several kinds of tubes that none of us in the USSR can produce at the moment! This regulator tube ...... Oh, my God...... From 3 volts to ...... 75 volts! Damn, it can't be! I would like to inform Comrade Alekseevich! ”

Ambassador Wang Jiaxiang was surprised: "What is this Comrade Alekseevich doing?" ”

Raminov said sincerely: "Mr. Ambassador, this is an expert from our country, and I can't say much about the rest." ”

Probably thinking that he might have offended the warm and kind Chinese comrades, Raminov kindly gestured with his hand to the movements of the Chinese he had seen.

Ambassador Wang Jiaxiang guessed in his heart: "Accounting? Call the accountant to come and make a counteroffer? Well, I'd like to see how you can pay back on the spot, anyway, I'm going to stick to the price list given by the central government. ”

Ambassador Wang Jiaxiang nodded, and said tentatively: "Comrade Raminov, look at this price list, this is the strategic material that we have obtained through our hard work to smuggle and break through the Western blockade, and this price is completely cost price. ”

Who knew that after a cursory glance, Raminov said: "No problem! I would wholeheartedly recommend that the Academy of Sciences take all these 100,000 tubes into account! ”

Who is this Alekseevich mentioned by Raminov?

This man's full name is Sergey. Alexievich. Lebedev is the director of the Kiev Institute of Electronics of the Soviet Ukrainian Academy of Sciences, which is nominally subordinate to the Ukrainian Academy of Sciences, but is actually a naval research institute of computing science fully funded by the Soviet Navy, specializing in the development of fire control computers for the Navy. In the early 1950s, the first tube computer "MESM" developed by them in the Soviet Union, with a computing power of 5,000 operations per second, it had already caught up with the American mainframe "ENIAC".

The Soviet Union's "MESM" used 6,000 tubes, which is much less than the more than 18,000 tubes of the "ENIAC" made by the Americans in 1946, but the computing power is the same 5,000 times per second, but the problem is the same, basically every 8 minutes to burn out a tube. The Soviet Union's "MESM" consumed 25 kilowatts per hour, while the American "ENIAC" was as high as 175 kilowatts.

Although today's giant machines seem to be strange things, at that time, they were a symbol of national strength! In 1950, the size of the giant computer alone had to be piled up on two floors, and the power consumption and pipe burning were natural losses, and basically only the leaders of the two camps could afford to play it, and it was a pure patent for burning money. A group of engineers in white coats waited on such monsters, constantly replacing burned tubes.

To get back to the point, as soon as Ambassador Wang heard that Raminov said that he would take it all over, he was relieved, and he was not worried that the Soviet big brother would not pay the money, so he left the train station and went directly back to the embassy after completing the handover.

Alexievich. Because Comrade Lebedev is engaged in the most secret and cutting-edge scientific and technological research in the country, he is generally only called by his middle name Alekseevich. As soon as Lebedev heard that the Chinese comrades had secretly obtained electron tubes smuggled from the British, he was immediately filled with curiosity.

For Soviet scientists, various types of electron tubes belong to the embargoed strategic materials, which have been cut off by the West since the beginning of the Cold War after World War II, and can no longer be obtained, and the progress of electronic science in the West can only be speculated from scientific magazines, or try to get a civilian electronic product from the West, disassemble and study it, and then estimate what the highest performance of Western military products is. Now, as soon as Lebedev heard about the arrival of a variety of products and fully calibrated jishu parameters, he immediately rushed from Kiev to Moscow.

When Raminov was shocked to inform the USSR Academy of Sciences and the Ministry of Defense of his amazing discovery, the USSR Academy of Sciences immediately notified the military and directly sent a batch of tubes of various models to Kiev with the Il-12 transport aircraft.

Kiev Institute of Electronics Jishu.

The five-story research building is surrounded by green grass, barbed wire is pulled high on the lawn, and the gate is heavily guarded. Inside, in the operation hall on the second floor, the floor is spotless with light gray paint, except for the soft sound of fans and humming central air conditioners.

Lebedev, the director of the institute, stood in front of this "MESM" and looked straight at the watch in his hand.

It had been more than an hour since the start-up operation, and Lebedev informed all the engineers that he would notify him as soon as one of the 2,000 new pipes that had just been replaced was replaced, but after more than an hour, the Soviet pipes were constantly broken down and replaced, but none of the smuggling pipes provided by the Chinese comrades had any problems.

Once one of the tubes of a mainframe computer burns out, the engineer pulls down the switch on the side, cuts off the local power supply, unplugs the socket, and plugs in a new socket with a row of 10 tubes. Then carefully remove the obviously blackened waste tube from the replaced row seat and replace it with a new one, so that the row seat is put back on the spare parts cart and waiting for the next breakdown to be replaced......

Two hours, three hours...... During this period, Soviet pipes were constantly replaced, and Chinese pipes were plugged in, but as long as the smuggling pipes provided by China were plugged in, there would be no more problems!

Finally, ten hours later, the first penetrated Chinese smuggling pipe appeared, and the second penetrated Chinese smuggling pipe appeared 12 hours later.

"These jishu indicators are not lying! Amazing craftsmanship! Terrific! The British raised the level of tube manufacturing for at least twenty years! Lebedev exclaimed.

"I command! Downtime for maintenance! Remove all the domestic pipes! Put all the new tubes on it! Lebedev made up his mind decisively and immediately ordered.

Lebedev's mood was really excited, and seeing the stable and outstanding performance of the "child" he had created by himself, he paced excitedly in the spotless, bright and tidy operation hall.

"Just replacing the high-performance diode has such a performance, what if I replace all the voltage regulators in front of each set of seats with China's high-power voltage regulators? What if the thyristor of the bus was replaced with a Chinese one? What if all the oscillating tubes in front of the mercury oscillation memory were replaced with Chinese tubes? ”

At the thought of this, Lebedev almost jumped with excitement. He didn't even look at the drawings, rushed out of the control room, rushed into the machine room, and ordered the engineers who were busy replacing the pipes: "Replace them all!" Swap them all! Oscillating tubes! Regulator tube! Diode! Transistor! Replace all the pipes with Chinese pipes! ”

"MESM" whirred like a sleeping child, and since last night, after the Navy's ballistic calculations were fed into the computer's tape reader, he has been working so gently and calmly until dawn that it spits out the punched paper tape recording the results of the calculations. The white-robed priests carefully rolled up the paper tape, placed it in a paper bag with the words Top Secret written on it, carefully sealed it, and handed it to the naval officers who had waited for 14 hours through the large glass window.

After the calculation was completed, a new perforated paper tape containing the nuclear physics data commissioned by the Soviet Institute of Chemical Physics was quietly and slowly fed into the paper tape reader by the white-robed holy priests, and 36 hours passed, and the white-robed priests slowly spit out the calculation results, and the white-robed priests carefully rolled up the paper tape and handed it to the scientists waiting outside the glass window of the operation room. These nuclear physics scientists watched with admiration as if on a pilgrimage, as if they were wearing white robes and able to communicate with the gods. They respectfully put away the top-secret paper bags and left the shrine under the escort of armed officers.

The white-robed priests took out a paper tape of data commissioned by the Soviet Institute of Optics and Physics and put it into the mouth of the gods......

High Priest Lebedev's eyes were already red, and he took a nap and then another nap in the control room, and after two days in a row, only three Chinese pipes were penetrated.

High Priest Lebedev slowly stood up from his chair and announced, "Shiyan success, these tubes...... Fantastic......"
