    What hardware are they focusing on? Vax11? IBM 360?

    Is it just me or is there something serious missing here?

      IBM is still making new mainframes. With all those obsolete mainframes collecting dust in the back office, it makes sense to repurpose them with Linux.

      Yeah, who needs a mainframe when you can just as easily install Linux on your typical 100 CPU, 3TB RAM server from Dell.

        Can you replace a faulty CPU in the Dell while it's running?

      IBM z series Mainframes which replaced the 390 which replaced the 370 which replaced the 360 that was phased out in the late 60s. You can run a couple thousand virtual Linux images on a single mainframe and have a complete web farm with database, etc in a single machine.
    • I can't find the original article I read where in the late 90's an IBM employee worked out how to partition a mainframe for Linux. But they did offer it and actually helped get Linux accepted as many began to say "If IBM backs it it must be good". The best link I could find on this is from 2001:

      You do realise that those machines are circa 1970's and rightfully belong in a museum. You would be really hard pressed getting parts for them.

      If you want older still usable machines I suppose you could look at the HP9000 series (still being made) or the IBM 7026-6m1 which was the last IBM machine I worked on in 2004 yet is still usable today. The IBM machines even in 2004 were very capable of running Redhat or CentOS Linux in an LPAR.

      Shooting from the hip, but to me a mainframe is not the same as "a huge computer"; I know some people think it is. Mainframes tend to be engineered for reliability more than anything else, as well as for fast i/o; they are usually rather specialised computers in many ways. The OS often seems a bit simplified compared to Linux, Windows or OS/X.

      It also often surprises people that many of the hot, new features we are still getting used to started their lives in mainframes: virtual machines is one that springs

    Several years ago my apartment complex in Silicon Valley had a gather your recyclables event at the leasing office and the flyer had a detailed list of what was acceptable to turn. I noticed mainframe on the list. Alas, no one put a mainframe out for pickup.
  • They have Linux partitions on their OS/390 mainframes. It's been a while since I last touched it (must have been 12 years ago or so?), and it was behaving quite odd at the time (not many utilities, strange idea of what root constituted, and that horrible, horrible shell), but still... the idea is a bit older than today.

      Are you thinking of Linux partitions or of UNIX System Services [ibm.com] for OS/390 (and z/OS)? The former is Real Live Linux running as an OS; the latter is an add-on environment for MVS and its successors, providing some level of POSIX/Single UNIX Specification compatibility, but with, for example, EBCDIC rather than ASCII as its character set.

        I remember fiddling around with USS a bit on zOS. Kind of strange, but you could actually do some things once in a while that way that were much easier than trying to destroy one's brain on the twisted mess called JCL.

        You're right. I was thinking of USS.

    This could be the year of Linux on the Mainframe.

    • by Anonymous Coward

      That could have been funny.... ...except most new System Z are sold with full Linux support. Telia (Swedish TelCo) said about 10 years ago: "Why run Linux on x86 when we can run 2000 Linux instances on the smallest System Z?"

    • Is there a compelling reason to prefer Linux to the BSDs when it comes to the mainframe? I know none of the mainframes had Unix running on them, but AIX was ported to some of them.

      Now I know AIX was based on System V rather than BSD, but does it have more similarities to Linux than it does to BSD?

      • by naris ( 830549 )
        The current mainframe operating system, z/OS, is a combination of AIX and MVS so it can run traditional mainframe programs alongside unix programs in the same OS.

        Well, there's the fact that the mainframe manufacturers (read: IBM) actively support Linux on their systems, and will happily sell you a mainframe with Linux pre-installed. In fact, that's more-or-less the standard configuration these days, as I understand it. http://www-03.ibm.com/systems/... [ibm.com]

        I know none of the mainframes had Unix running on them [...]

        Your knowledge is extremely out of date. RH, SUSE, and even Debian have been actively supporting IBM mainframes for years, with active help and support from IBM. Linux has been running on mainframes in datacenters for

        • Aside from making it easier to port software TO the mainframe, IBM has priced additional capacity *limited to running Linux* much cheaper than native z/OS. So IBM mainframe shops have a strong incentive to add incremental workloads on Linux.

  • IBM is what they're targeting. It's a laundry list of tech improvements Linux on the Mainframe that are, let's face it Mainframe/IBM specific.

    JIT for OpenJDK, where the project will work on adding JIT support to the z port of OpenJDK.
    Docker support to enhance Docker for highly available virtualized systems and mainframe computing environments.
    Blockchain support that will focus on performance and improvements to the Hyper

  • The project also announced a great internship program, helping pair students with mentors with deep mainframe experience to help build the open source platform.
