Reborn Before the Apocalypse: My Backing is the Nation

Chapter 218 This Life Is Different!
Earth's supercomputer!

When Jiang Yang uttered those four words, every attendee felt a jolt of shock.

Hundreds of billions of computing nodes, utilizing all the electronic computing devices in the hands of every human being, a globally distributed computing network, pooling the power of all humanity, to calculate and search for that usable trajectory...

Jiang Yang said in a deep voice: "Statistics from the previous life show that the total computing power of the world's top 1 supercomputers is about 10 ZFlop/s."

With a global population of tens of billions, including personal, commercial, and research users, the total number of computers, mobile phones, smartwatches, servers, etc., is estimated to be over 1 billion, with a total computing power of approximately 10 YFlop/s, about 1000 times that of the world's top 1000 supercomputers!

Flop/s is a unit of computing power, which refers to the number of floating-point operations that can be performed per second.

Floating-point operations can be simply understood as a math problem: 0.46 multiplied by 1.75, 15566 divided by 75.5, 5548.5 plus 66.45, etc., are all math problems.

When a computer calculates such a mathematical problem, it can be said that it has performed a floating-point operation.

The combined computing power of the world's top 1 supercomputers is approximately 10 ZFlop/s, meaning that these computers combined can perform an average of about 100 quadrillion floating-point operations per second.

The combined computing power of all electronic computing devices owned by the global population can reach 10 YFlop/s, which means that on average, approximately 10 quadrillion floating-point operations can be performed per second.

This computing power is so massive it's almost unbelievable.

With a global population of billions, assuming each person can solve this math problem every 10 seconds, the total amount of calculations performed by all the computers in the world per second, even if they didn't eat, drink, or rest, would take approximately 3 million years to complete.

This is the scale of computing power that the entire human world has finally possessed after more than a hundred years of accumulation and iterative optimization since the birth of electronic computing devices.

"Of course, requisitioning all of these devices and putting them all into calculations is merely an ideal scenario."

In the previous life, after a full mobilization, the amount of computing power ultimately invested in calculations was approximately 70% of the total, or 7 YFlop/s.

This is because verification calculations are required, meaning that each calculation task needs to be assigned to three different devices for joint calculation, and the correctness of the task is determined by whether the final calculation results are consistent. In addition, 66% loss needs to be removed, leaving approximately 2.31 YFlop/s of computing power.

Of this, due to factors such as data communication speed and uncontrollable forces, we need to deduct about 50% of the computing power, so the final computing power we have left is 1.15 YFlop/s.

However, even if the remaining computing power is only 11.5% of the ideal computing power, this figure is still 115 times the total computing power of the world's top 1 supercomputers combined, which is more than enough for use!

Jiang Yang looked at Professor Lu Zhaoming: "In the previous life, we only used the computing power of the top 1 supercomputers to undertake task distribution, task collection, final review and verification, and did not perform any calculations at all."

All the computing tasks were accomplished by the computers, mobile phones, smartwatches, and fitness trackers in the hands of 100 billion people worldwide!

Professor Lu Zhaoming's eyes were filled with shock.

Looking at Jiang Yang's determined eyes, he murmured, "In that case, our computing power is more than enough. We can definitely find that complex trajectory!"

A computer expert pressed the speak button. After being granted permission, he asked somewhat eagerly, "Comrade Jiang Yang, may I ask what method we used to build this distributed computing network in our previous life?"

"It's too large and too complex. Do we really have the technology?"

Jiang Yang knew that building such a globally distributed computing network was incredibly difficult.

Humanity has actually explored distributed computing many times before.

For example, the well-known Bitcoin is essentially a distributed computing network. Similarly, the equally famous Berkeley Open Network Computing Platform uses a model that distributes computing tasks to numerous personal terminals to perform calculations for problems such as the search for extraterrestrial life and protein folding.

However, this approach is severely limited; it is either too inefficient or can only perform calculations for specific tasks, making it impossible to apply on a large scale.

It's no wonder the computer expert in front of him was so anxious and shocked.

In this life, Jiang Yang has not yet had any dealings with him, but Jiang Yang already knows his name and is very familiar with him.

"Professor Liu Xisheng..."

Looking at the expert, Jiang Yang's gaze was somewhat complicated: "This is a question that you shouldn't be asking me, but rather that I should be asking you."

Professor Liu Xisheng paused for a moment.

Jiang Yang slowly said, "Because in the previous life, it was your team of experts who completed the first version of the Earth's supercomputer program in ten days and carried out verification calculations on the scale of tens of millions of nodes."
Within twenty days, the number of nodes expanded to one billion. Within a month, global coverage of Earth supercomputing was achieved, connecting a total of 787 billion personal nodes to the Earth supercomputing network and ultimately completing the computing task.

You and your colleagues worked very hard in your previous life.

Professor Liu Xisheng remained in a daze.

Jiang Yang's mind was filled with images of his past life.

At that time, a team of computer experts led by Professor Liu Xisheng, totaling more than 1 people, used the method of injecting psychotropic drugs to maintain their working state at the beginning of the mission. They only rested for an average of two hours a day, and devoted the rest of their time to work.

It's common for them to go three or four days without sleep.

Under this extremely demanding work schedule, more than 100 experts died suddenly on the job when the first version of the program went live.

A month later, the Earth supercomputer was officially launched. The number of experts who died suddenly eventually exceeded 1,000, and another 5000 suffered varying degrees of mental damage, and it is unknown whether they can recover.

The remaining people all fell seriously ill and were unable to leave the hospital until the final apocalypse.

Professor Liu Xisheng, standing before me, suffered from severe schizophrenia due to the stimulation of psychiatric drugs, becoming a madman. But…

This life is different!
Jiang Yang's expression was full of determination: "Professor Liu Xisheng, in my previous life, after your team completed the mission, you summarized six engineering experiences for building an Earth supercomputing network."

I remember in my previous life, during your few moments of lucidity, you told me with pain and self-blame that if you had known these six engineering principles earlier, not only would the efficiency of the mission have been greatly improved, but there would also have been fewer casualties in your team.

Now, I bring with me the experience you and your colleagues gained at the cost of your lives and health, as well as the key technological principles for building Earth's supercomputer. In this life, you can use it directly without having to pay such a high price again.

Professor Liu Xisheng looked somewhat dazed.

"Did we already accomplish this once in our previous life?"

"Yes."

His expression gradually hardened: "Then in this life, we can definitely complete it again."

Jiang Yang nodded and looked at the decision-makers of the World Government decision-making group.

"The last hurdle has been removed. What will you decide?"

The leader of the decision-making group had a somewhat complicated expression.

He paused for a moment before whispering, "Just as I said before, a solar system and universe without humans are meaningless to us."

We are willing to pay any price to ensure the continuation of civilization.

"If that's the case... then let's escape the solar system!"

Not a single one of the hundreds of decision-making and deliberative committee members, or the thousands of attendees, voiced any objection.

Jiang Yang turned to look at Professor Yu Qing.

"In that case, the amount of hydrogen bombs used in this generation should still be considerable."

Professor Yu, in my previous life you led the production of 360 million hydrogen bombs; in this life, we need you to do it again.

Professor Yu Qing stood up and calmly said, "I guarantee to complete the mission."

Looking at his calm face, Jiang Yang's mind was once again filled with the image of him in his previous life, lying on his sickbed with no will to live.

Fortunately, there is still a chance to start over.

"Professor Yu, in this life, I require you to strictly adhere to radiation protection requirements. I will apply to the World Government to appoint a special person to supervise you."

Professor Yu Qing looked slightly surprised.

"The previous life... never mind."

Jiang Yang did not recount those experiences, but only said: "The nuclear proliferation project will create more than 10 billion tons of nuclear wastewater, which will have a serious impact on the Earth's ecology."

But in this life, if the salvation plan fails and the Earth is destroyed, you don't need to worry about nuclear wastewater;

If the salvation plan succeeds and Earth escapes the solar system, the ecosystem will be completely destroyed anyway. Therefore, a tiny amount of nuclear wastewater will be insignificant, and you don't need to feel too much psychological or mental stress.

Professor Yu Qing was increasingly surprised: "Why should I have mental pressure? Also, as a nuclear physicist, strictly adhering to radiation protection is my basic professional duty. Why should someone be assigned to supervise me?"

Jiang Yang didn't answer, but simply nodded: "That's good."

The frameworks for the hydrogen bomb manufacturing and Earth supercomputing projects have been established; only one final item remains.

He looked at Gu Changshan.

In his previous life, he was the one who executed the space port project, successfully completing the mission of transferring 360 million hydrogen bombs from near-Earth orbit to deep space.

There will inevitably be a large demand for hydrogen bomb transfers in this lifetime, and the space port project will need to be carried out again.

But this task is different from Earth supercomputing.

Earth supercomputing missions can leverage their key technological frameworks and engineering experience to significantly reduce casualty rates.

Spaceport missions are similar to "labor-intensive" missions, with low technological content. Even with engineering optimizations, the reduction in casualties is limited.

Watching one soldier after another sacrifice would be an immense mental burden for any commander.

Looking at Jiang Yang's expression, Gu Changshan seemed to understand something.

"I accept this task."
