Quadrics Linux Kernel Patches


The addition of the Quadrics kernel patches provides the following functionality:

  • The ioproc patch provides support for communicating from pageable memory.
  • The ioproc patch avoids the need to lock down memory used in inter-process communication; the Quadrics libraries will do this automatically if the ioproc patch is not installed.
  • The ioproc patch supports use of mmap/munmap when alocating communication buffers.
  • The ptrack patch provides job containers for the processes in a parallel jobs; this simplifies cleanup and accounting operations in RMS and third party resource managers.


    • qsnetpatches

    The patch files are provided in kernel version specific, qsnetpatches, Open Source tar archives. Users should read the Quadrics Linux Kernel Integration document for intructions on how to apply the patches and build a patched Linux kernel. The Quadrics Linux Kernel Integration document is also included in text or html format as a README in the qsnetpatches tarball.

    The QsNet patches are provided "as is" without any warranty; without even the implied warranty of merchantability or fitness for a particular purpose. Please see the Support Overview page for information about purchasing support for Quadrics software.

    Plans for supporting new kernels can be seen on the Quadrics Linux Kernel Roadmap page.

    The letters in the architecture boxes indicate the level to which each version has been tested on the particular architecture. The key is as follows:

    S : Supported versions. Quadrics will provide support for this version to customers who have paid for software support.
    T : Quadrics has verified that the patches apply correctly and that the resulting kernel boots and runs parallel programs.
    N : Not tested but should work.
