IBM to Reveal Details of New Cell Chips

Filed under

IBM Corp. planned to reveal key details of its highly anticipated "Cell" microprocessors Wednesday as part of the company's effort to support open-source computing designs.

The specifications were due to be released in Barcelona, Spain, to encourage a deep pool of developers to create applications that can work with Cell when it is released next year.

Cell, which is being jointly designed by IBM, Sony Corp. and Toshiba Corp., has nine separate computing engines, known as "cores," to carry out multiple functions at once.

The highest-profile deployment promised for Cell is in Sony's coming PlayStation 3 game consoles, but IBM also expects the chip to be useful in such high-performance systems as supercomputers, medical imaging machines and military hardware.

Chip makers routinely share designs on their systems so that outside parties can write programs for them or build other chips that are compatible. But IBM contends that it is going to exceptional lengths because it will not charge developers licensing fees or force them into nondisclosure agreements.

Jim Kahle, IBM's lead designer for Cell, said the company essentially will "donate four years worth of intellectual property to the open-source community."

However, this effort differs from open-source software programs such as Linux, in which a community of programmers has general license to tinker with the product's design and use it wherever they want. IBM retains the rights to make the chips.

  • Vulkan 1.1.71 Released As The First Update To Vulkan 1.1
    The first point release to the Vulkan 1.1 release from earlier this month is now available. Vulkan 1.1 promoted a lot of functionality to core while also officially adding sub-groups and protected content support. This Vulkan 1.1.71 point release adds a new extension and fixes. This first point release to Vulkan 1.1 is officially version 1.1.71. This is because when Vulkan 1.1 was created, Khronos decided not to reset the patch number... Vulkan 1.1 was technically 1.1.70 and not 1.1.0. So now with this first update it's bumped to Vulkan 1.1.71.
  • AMDVLK Vulkan Driver Updated With Improvements For Sub-Groups & Multi-View
    The AMD developers working on their official cross-platform "AMDVLK" Vulkan driver have updated their open-source code-base for Linux users. On Friday the AMD developers pushed to the open-source repository their latest work, their first update since introducing Vulkan 1.1 support back on launch day earlier this month.

    Google this week announced that it will open its Maps APIs to video game developers, which could result in far more realistic settings in augmented reality games. With access to real-time map updates and rich location data, developers will have many choices of settings for their games. The APIs will provide devs with what Google has described as a "living model of the world" to use as a foundation for game worlds. Developers will have access to more than 100 million 3D buildings, roads, landmarks and parks from more than 200 countries around the globe.

    Stack Overflow’s annual survey has revealed the tools and tech that developers love to hate: Visual Basic 6, IBM Db2 and SharePoint. According to the poll, which took in the views of more than 100,000 devs, Rust is the most loved programming language for the third year running. It is closely followed by Kotlin, which makes its debut in the survey. [...] At the other end of the spectrum is Visual Basic 6, which has been voted most dreaded programming language. Visual Basic 6 is also linked to lower pay, with Stack Overflow saying that devs using it are “paid less even given years of experience”.
