Italy
Italy closes this rating. The country has 5 supercomputers. This is 1% of the total number in the world. The most powerful supercomputer in the country is HPC 4. It was developed by the Italian oil and gas company Eni. The peak performance of this computer is 18.6 PFLOPS. Its main task is to carry out seismic exploration. HPC 4 is located at the data center in Ferrera-Erbognone, Northern Italy. It is also used to reduce energy consumption and preserve the environment. Developers installed in this supercomputer air cooling instead of liquid cooling that makes it more energy efficient.
For nearly a century, the US-based weekly periodical Time has closed out the year by selecting the person who has had the most significant impact on the global stage—not necessarily a positive one. This year, the magazine's cover features Donald Trump, who recently won the US presidential election. Let's find out who else was honored by Time and in which nimonations.
Following his election victory, Donald Trump, a billionaire himself, once again decided to include prominent magnates in his administration, as he did during his first presidential term. As a result, Trump's current cabinet features seven billionaires, making it one of the wealthiest in US history. Let's find out who these billionaires are and the roles they have been assigned.
Not long ago, the United States held a presidential election, where Donald Trump emerged victorious. Today, he is recognized as the wealthiest American leader in the country's history. Let's take a closer look at other former US presidents who also achieved significant financial success.
