In recent days, the movement of新 has entered into a strategic cooperation agreement with the Chinese South Air Shareholding Company Ltd.分 (hereinafter referred to as the New Frontiers of South Navigation). The Commander-in-Chief of New Border Movement attended the signing ceremony.

In his message, the Commander of the New Border Mobile Master indicated that, as the central bank of communications in the border, the新 moved further to build on a good partnership between the two sides, building on the advantages of network resources, client size and brand value, working together with the New Frontiers of the South Sea to accelerate the implementation of the cooperative elements and to work together to create an ecological circle of “digital services”.

Under the agreement, the New Frontier Movement and the New South Air Shareholding Corporation will take full advantage of its corporate strengths and will work to deepen strategic cooperation and to continuously upgrade its core values and service capabilities through the establishment of strategic partnerships, in-depth cooperation in basic operations, joint benefit products, large data, exchange, information applications.

This was followed by a visit by a member of the Yuzhmorgeologiya company, who also visited the智’s mobile 5G intellectual experience office, to gain an in-depth understanding of the elements of the Mobile Star Party, the Intellectual Traffic, the Wise Brigade, the Wise Family, and to fully acknowledge the effectiveness of the movement of the new frontier in the use of the 5G technology endowment.

With visible results, it would be more confident of the movement of the new frontiers by the Yuzhmorgeologiya, and it was hoped that operational cooperation with the new疆 would be expedited in the future.

As a large part of the well-known marketing operations in the industry, the cheon has been able to perform well since his advancement in the new frontier. Not only has marketing capacity been successful, but there is also a strong capacity for government business.

This year, the movement of the new frontiers has been frequently hit in the field of business, with the participation of the Boundary Energy Group during the signing of the strategic cooperation agreement in April, the Deputy Chief of the New Border, Lee, the Chief of Staff, the Chief of the Cabinet, and the Makarim, the General Manager of the Department of Political and Business.

The earlier March of this year, the new frontier moved with the Bank of Emergencies, the “5G + financial” digitization of finance, and conducted operational discussions.

Nowadays, mobile workers in the new frontier are morale, while the replacement of the deputy chief executive of business in the telecommunications branch of the new border has opened the door to the new frontier, which is also an opportunity for the new frontier to move on government business.

The Standing Committee of the Province of Henan and the Deputy Governor of the Standing Committee attended and addressed the meeting. He stressed that, as a provincial corporate financial institution, leading groups at all levels of the Bank of Central America should first be united. At the same time, it is imperative to work together, led by the General Party Committee, to implement the central spirit and provincial council’s call for a genuine contribution to the building of modern rivers. Effective risk prevention is required. There is no systemic risk bottom line that must be put in place. Active development. Insisting on identifying the real economy of the service provider and pursuing its own development, in root, deep-rooted, middle- and middle-served, providing better-quality financial services and solid financial support for the development of “two guarantees”, the implementation of the “10 strategies”. It is essential that the bottom line be maintained with integrity. Insisting on the integrity of the party as a regular exercise, with a party’s strength, it seeks to create a climate of integrity, integrity and integrity, building the mindsets of the members of the Penitentiary Party, “undesirable, incompetent, non-perishable, undesirable”, and making the financial integrity a new name and a call for the development of the Bank.

“NVIDIA is one of the most troublesome hardware manufacturers we have encountered.” That’s what Linus Torvalds, the chief designer of Linux kernel, said ten years ago.

At that time, Linus was being interviewed at the student and developer seminar held by Alto University in Helsinki, Finland. At the meeting, a live audience said that they had bought a laptop equipped with integrated graphics card and NVIDIA independent graphics card, However, under Linux, the switching between independent graphics card and integrated graphics card through NVIDIA Optimus technology is not supported by the driver (NVIDIA Optimus is a dual graphics card switching technology developed by NVIDIA, which can realize seamless, automatic and real-time switching between independent graphics card in notebook computer and built-in graphics card on motherboard), and asked Linus for his idea. It was in this context that Linus said the above sentence, then turned to the camera lens, raised his middle finger and burst out foul language.

As the father of open source operating system Linux, Linus has always been a loyal supporter of open source. He has always hoped that NVIDIA can open source their drivers. Now, this day has come.

Just now, NVIDIA announced that they open source their own GPU kernel driver module, which caused a sensation in the developer community.

Someone commented, “this is one of the biggest events in the hardware support of open source operating system in the past decade.”

Others joked that this was a “long live” moment.

This open source uses dual GPL / MIT licenses, starting with the r515 driver version. Developers can find the source code of these kernel modules in NVIDIA open GPU kernel modules repo on GitHub: https://github.com/NVIDIA/open-gpu-kernel-modules

NVIDIA said that this open source will greatly improve the experience of users using NVIDIA GPU in Linux system, make it more closely integrated with the operating system, and facilitate the debugging, integration and feedback of developers. For Linux distribution providers, the open source kernel module increases ease of use and improves the out of the box user experience to sign and distribute NVIDIA GPU drivers. Canonical and SUSE can immediately package these open source kernel modules with Ubuntu and SUSE Linux Enterprise distributions.

Developers can track code paths and learn how kernel event scheduling interacts with their workloads for faster root cause debugging. In addition, enterprise software developers can now seamlessly integrate the driver into the Linux kernel customized for their projects. This will further improve the quality and security of NVIDIA GPU drivers and get feedback from the Linux end user community.

Supported functions

The first version of the GPU kernel module released this time is r515. In addition to publishing the source code, this version also provides a complete build and packaging version of the driver. For the data center GPUs in NVIDIA Turing and NVIDIA ampere Architecture series, these codes can be used for production. This is due to the GSP driver architecture launched by NVIDIA in stages in the past year, which aims to make it easy for NVIDIA customers to transition. The R & D team focused on testing various workloads to ensure the same functionality and performance as proprietary kernel mode drivers.

In the future, HMM and other functions will become the basic components of confidential computing on NVIDIA hopper architecture.

NVIDIA’s open source version has high support for geforce and workstation GPU. Geforce and workstation users can use this driver on NVIDIA Turing and NVIDIA ampere architecture GPU to run Linux desktop, and use functions such as multi display, g-sync and NVIDIA RTX ray tracing in Vulkan and NVIDIA Optix. The user can choose to use the kernel module parameter nvreg highlighted in the document_ EnableUnsupportedGpus 。 More powerful and full-featured geforce and workstation support will be released in subsequent versions, and NVIDIA’s open source kernel module will eventually replace the closed source driver.

Customers with Turing and ampere GPUs can choose which modules to install. Customers who use the hardware before Turing will continue to run the closed source module.

Open source kernel mode drivers use the same firmware and the same user mode stack, such as CUDA, OpenGL, and Vulkan. However, all components of the driver stack must match the version in the distribution. For example, users cannot publish source code, build, or run it using previous or future versions of the user mode stack.

Why is NVIDIA’s open source driver so important to Linux?

Shortly after NVIDIA announced open source, Christian f.k. Schaller, senior Desktop Manager of red hat, an open source solution provider, published an article entitled “why is the open source driver release from NVIDIA so important for Linux?” Blog post, in-depth interpretation

Eggs should be used

Experiment or eat?

As early as the early stage of reform and opening up, Chinese educational researchers have introduced foreign advanced teaching models to optimize Chinese classrooms, including inquiry and discovery teaching. However, such methods are more suitable for scholars with college education or above to study and explore, rather than guiding students to learn knowledge in the classroom. In the following decades, many Chinese scholars have continuously introduced many foreign educational ideas and conducted research and discussion in order to find the teaching methods most suitable for China’s national conditions and students’ actual situation.

In 1985, the decision of the CPC Central Committee on the reform of the educational system was issued, requiring all parts of the country to deepen educational reform and strive to do a good job in experimental teaching. At that time, both teachers and students were unfamiliar with the experiment. First of all, the vast majority of teachers have been receiving traditional education in the process of growing up. They also continue this form of education and teach students. The addition of “new forms” is difficult for teachers and students who have solidified their thinking mode and learning habits to adapt quickly. And there are not enough teaching instruments, equipment and experimental places. Experimental courses, slow development.

In 2001, the Ministry of Education issued the notice on printing and distributing the opinions on carrying out the experimental promotion of the new curriculum of basic education. According to the requirements of attaching importance to practice and experimental teaching in the new curriculum, strengthen the construction of educational and teaching facilities such as laboratories and improve their use efficiency, and promote the construction of student activity places and social practice bases; Two years later, the Department of Physics Education issued “what is the standard of inquiry ability and what is the standard of inquiry ability of students in high school”. Since then, scientific inquiry has been popularized and implemented nationwide, but some teachers still haven’t really implemented scientific inquiry into teaching. The reason is not only the tense class hours and the lack of teachers’ ability, but also the pressure from paper and pencil examination. From the college entrance examination to the in class test, they are all paper and pencil tests, and students’ scores have become a shackle to the implementation of experimental courses.

In 2009, the Ministry of Education issued the regulations for primary and secondary school laboratories, which requires the construction of primary and secondary school laboratories as an important content of comprehensively promoting quality education, deepening curriculum reform and improving education quality; Ensure the annual growth and use efficiency of laboratory construction funds in primary and secondary schools. The experimental related education in rural primary and secondary schools has been further improved.

Experimental examination,

Beat “exam taking” with exam taking

With the continuous promotion of national policies for more than 20 years, experimental courses have entered schools large and small. Under the background of the new curriculum reform, the experimental course is also paid more and more attention. Teaching students knowledge through experiments is undoubtedly one of the teaching methods with strong experience, participation and memory. However, there are still gaps in experimental teaching equipment and classroom configuration in different regions, and the guarantee funds for experimental teaching are also different in different regions. Laboratory equipment also needs to be updated and upgraded regularly to ensure the safety of the experiment and the accuracy of the results, which will also be a large cost. And most of the experimental courses are attached to the subjects of physical and chemical students. In the past for a long time, some colleges and universities lacked special personnel to be responsible for the size of the laboratory. Trying to become a high-frequency experimental classroom, it has become an unattended field of “black under the light”.

In addition, under the pressure of examination oriented education in senior grades, the large-scale implementation of experimental teaching seems to be a “waste of time”. In addition to the necessary experimental projects, teachers rarely take the initiative to increase. Under the whirlpool of exam oriented education, in 2019, the opinions of the Ministry of education on strengthening and improving experimental teaching in primary and secondary schools was released, which said that we should open up experiments stipulated in national curriculum standards and effectively reverse the tendency of ignoring experimental teaching. It is clear that the experimental operation should be included in the junior middle school academic level examination before 2023, and the examination results should be included in the basis of enrollment in senior high school; In the general senior high school academic level examination, qualified areas can include the experimental operation of physical and chemical students into the provincial unified examination. Boost the rapid development of experimental courses from the examination end. Subsequently, in 2021, nearly 20 provinces or cities across the country issued the implementation rules for the physical and chemical students’ experimental operation examination of the middle school entrance examination:

Although the proportion of experimental operation in the overall score of the middle school entrance examination is not high, it has shown that the experiment has become an indispensable part in the future education and teaching work. In fact, the experimental part has been added to the junior middle school academic level test in some areas in the early years. However, limited by the examination room equipment, the final presentation form of the experimental examination only exists in the report. The ability and standard of experimental operation are not included in the assessment. In other words, even without experiment, students can “simulate” to answer such an answer sheet with known answers.

If the standard of experimental operation is included in the examination results, it will be more difficult to read and judge the “test paper”, and further requirements need to be made for the invigilator, the examination venue and the ability of data transmission (text, picture and video data). In May 2021, the China Education Equipment Industry Association issued the China education equipment industry group standard technical specification for experimental operation evaluation system, which clearly incorporated AI scoring into the experimental operation evaluation technical system, and steadily promoted the application process of AI scoring according to the three stages of exploration period, probation period and practice period. However, the differences of scoring standards between different regions, the types of experiments and the types and models of application instruments all make it difficult for AI marking. At present, there is no case that AI is fully used for formal examination in China. Shanghai, Shenzhen and other places at the forefront of innovative application still use teacher scoring as the main evaluation means, and AI scoring is only used as an auxiliary means to carry out pilot in a small range.
