Oracle Linux 7.9 released: Based on Linux 5.4 LTS and UEK 6 Enterprise Kernel Construction

-

 

As for the Linux 5.4 LTS long-term support kernel, it has introduced many new features and improvements to provide first-class hardware support. For example, use zero-copy network to improve network performance, support Btrfs / OCFS2 file system and DTrace, as well as security enhancement and virtualization support for AArch64 (ARM64) platform. UEK Release 6 includes all Cgroup v2 features of Linux 5.4 LTS, a new parallel optimization framework for CPU-intensive work, and kswapd and kexec for verifying the signature of kernel images. In addition, it supports NFS network file transfer, and can treat persistent memory as traditional RAM NVDIMM, NVMe structure/multipath support, pass-through commands, namespace write protection, and asynchronous namespace access improvements. Users who are currently using Oracle 7 major versions can obtain the Update 9 update through the official resource repository, or visit the official website to download the complete ISO installation image of Oracle Linux 7.9.

In addition to the aforementioned UEK Release 6 features, Oracle Linux 7.9 also introduces some new features of the Red Hat Compatible Kernel (RHCK). For example, EDAC (error detection and correction) driver and reporting function for Intel ICX system, and support for Mellanox ConnectX-6 Dx network adapter. In other respects, the Update 9 release adds DIF / DIX (T10 P1) support for specific hardware. The FreeRDP remote desktop protocol tool has been updated to version 2.1.1, and the Pacemaker cluster resource manager has also been updated to version 1.1.23.

  Beijing time October 10 news, according to foreign media reports, the latest research shows that scientists should be able to create a "super magnetic field" on the earth, equivalent to the magnetic field strength of black holes and neutron stars. According to the latest research report by Masakatsu Murakami, an engineer at Osaka University in Japan, and his colleagues, bombarding microtubes with lasers can generate very strong magnetic fields, which will be of great significance for the development of basic physics, materials science and astronomy research. On October 6, this research paper was published in the open access journal "Scientific Reports". Most of the magnetic fields on the earth, even artificial ones, are not particularly strong. Magnetic resonance imaging (MRI) used in hospitals usually produces 1 Tesla (equivalent to 10,000 Gauss). In comparison, the magnetic field generated by the compass needle swinging northward is 0.3-0.5 Gauss, which is the m...

In particular, CEO Radoslav Danilak, who has 25 years of experience in the semiconductor industry, was founded by SandForce, a once-popular SSD control giant. He also personally served as CEO, was later acquired by Seagate, and later founded Skyera, and continued to study SSD control. Technology and then acquired by Western Digital in 2014. Tachyum Prodigy claims to be the world's first "universal processor" (universal processor) because it integrates for high-performance computing, AI artificial intelligence, DML deep mechanical learning, and interpretable in a single silicon chip based on a parallel multi-processor environment and can simplify the programming model and environment. The latest top model is Prodigy T6128, a single-channel single chip integrates 128 physical cores, out-of-order execution architecture, 4 instructions per clock cycle , supports 64-bit addressing, 512-bit vector operations, AI / ML vector and matrix multiplication acceleration, Virtualizatio...
