Webinar: The best Use Cases for RH Openshift Container Platform for IBM Z and LinuxONE

Join us for our webinar on Wednesday, December 2, 11:00 AM - 12:15 PM EST!

This session will show and explain when and how you can take advantage of the Red Hat OpenShift Container Platform on IBM Z and IBM LinuxONE. It illustrates the best use cases and why they fit best, with the dependencies on the business goals or technology challenges.
This presentation is part of the regular technical Linux on IBM Z and LinuxONE webinar session series from the IBM Labs. Find all past sessions here: http://ibm.biz/Linux-on-IBMZ-LinuxONE-Webcasts

New Release: qclib v2.2.1

qclib v2.2.1 is now available for download here.
This bugfix release marks the first release on our new home on github, which features the history back to v2.0.

For more information, see the README.

New Release: Red Hat Enterprise Linux 8.3

RHEL 8.3 is out, see the official announcement.
Highlights from a Linux on Z perspective:

  • Crypto: 
    • Use protected key dm-crypt for Linux systems with access to CryptoExpress adapters in EP11 mode
    • Now run the AES self test suite of the kernel automatically whenever the module is loaded, as required for a FIPS 140-2 certification
  • KVM:
    • Adds support for Secure Execution 
    • ECKD DASD can be transparently passed through to KVM guests, allowing full exploitation of all DASD features, including raw track access and IPL
  • Networking:
    • The qeth device driver improved handling of invalid frames
    • SMC-R gained high availability through so-called link group support
    • SMC-D gained forward-compatibility to SMC-Dv2
  • Storage:
    • Ability to IPL from NVMe devices
    • Various new sysfs attributes to query FCP-related information, e.g. use
      • /sys/class/fc_host/<host_name>/fabric_name to query the name of the connected Fibre Channel fabric
      • /sys/bus/ccw/drivers/zfcp/<fcp_device_bus_ID>/fc_security to query IBM Fibre Channel Endpoint Security capabilities of the FCP channel providing the FCP device bus-ID
      • /sys/bus/ccw/drivers/zfcp/<fcp_device_bus_ID>/0x<target_WWPN>/fc_security  to query status of authentication and encryption of connection between FCP device and remote port
  • Misc updates
    • opencryptoki v3.14
    • qclib v2.1
    • smc-tools v1.3
    • libatlas is now taking advantage of specific BM z13 and z14 instructions for performance improvements
For further details on the changes, see the release notes.
Also, take note of a distro-specific edition of our Device Drivers, Features, and Commands book available here.

New Release: OpenBLAS 0.3.12

The latest release of OpenBLAS comes with substantial improvements for single precision matrix multiplication on IBM Z. Thanks to a hand-tuned compute kernel, the implementation makes optimal use of the IBM Z instruction set to provide a big performance benefit. As an algebra library implementing the BLAS interface (Basic Linear Algebra Subprograms), OpenBLAS is a central building block for AI and other compute-intensive workloads. In a Linux system, OpenBLAS serves as compute back-end for many functions in NumPy, SciPy, R, and Octave.

For further details, see the OpenBLAS 0.3.12 release notes here.
