While modern x86-compatible processors, thanks to AMD, have reached the mark of 128 cores per CPU, processors based on the Arm architecture have long since crossed this mark, and this has become a problem. As it turns out, the Linux operating system is not yet ready for this.

The question was raised by Ampere, which released its 192-core CPUs on Arm. The problem is that two such processors in one system means 384 cores, and today the 64-bit main Linux Arm kernel build only supports up to 256 cores. To solve this problem, Ampere itself introduced a patch that proposes to increase the Linux kernel limit to 512 cores using the “CPUMASK_OFFSTACK” method. In fact, support can be increased to 8192 cores at once, but the limit of 512 was chosen for the sake of economy, since support for each CPU core adds about 8 KB to the size of the kernel image.

It is reported that without patches, support for more than 256 kernels in Linux will not appear until next year, when Linux 6.8 is released.

Speaking at the DealBook 2023 summit in New York on Wednesday, Elon Musk, owner of the social network X (formerly Twitter), ridiculed advertisers leaving the platform because of anti-Semitic messages he spread there.

“What if someone tries to blackmail me with advertising? Blackmail me with money? Go to hell. Go. F—. Yourself,” Musk said, singling out Disney.

On November 20, Apple said it would stop advertising on Platform X, two days after Elon Musk tweeted his agreement with an anti-Semitic post. A number of other major technology and media companies, from IBM to Disney, made similar announcements on Friday.

Elon Musk also stated that his fans will boycott these advertisers in response: “The whole world will know that these advertisers killed the company, and we will document it in detail. I have no problem being hated.”

In recent weeks, Musk has endorsed what the White House called “anti-Semitic and racist hate” on X. He called the tweets “one of the dumbest, if not the dumbest, thing I’ve ever done on the platform.” “I regret these tweets,” he added.

This week he also visited Israel, where he met and spoke with Prime Minister Benjamin Netanyahu. When Netanyahu said he wanted to “deradicalize” and “rebuild” Gaza, Musk offered to help. Musk said his visit to Israel was planned before his tweets and was not part of an “apology tour.”

Musk has previously said he wants to bring SpaceX’s Starlink satellite communications service to the region and, in particular, to humanitarian organizations in the Gaza Strip.

Microsoft’s Copilot assistant, integrated into Windows 11, will soon move to the GPT-4 Turbo language model.

General Director of Advertising and Web Services at Microsoft, Mikhail Parakhin, said that the company still needs to correct some shortcomings. However, no time frame for the transition has been announced yet.

As a reminder, GPT-4 Turbo features a large number of improvements relative to GPT-4, including a context window for 128,000 tokens. True, with Copilot it may well be limited.

In addition, this language model is trained on data up to April 2023, which gives it an advantage over older versions.
