Overview compares emulation strategies

MBFA Emulation OptionsMB Foster has put some of its Wednesday Webinars online for streaming. A link to a web page leads to a form for input of your name and email, and eventually a return message gives a link to the streams. The company has a lot of firsts to its name for transition training, and this might be the first delivery online of 3000-specific advice since HP's migration broadcasts of 15 years ago.

Much of the online content wraps around the MB Foster product line: UDACentral, UDASynch, and MBF-Scheduler all have webinars. One broadcast, though, promises to be one of the first overviews of emulation strategies. These are the ways customers can re-host HP 3000 applications. Virtualization, using the Charon HPA solution from Stromasys, is the ultimate solution discussed in 45 minutes of presentation.

"I don't think there's anybody else in the marketplace that's given an overview of the emulators," said MB Foster's Chris Whitehead. "It's been up to each individual company to decipher what they can and cannot use."

He's right, and the webinars from early this year and the middle of last year give a broad overview of what emulation might look like. It's an interesting term with many definitions, according to our overview. For some planners, this word means getting away from MPE/iX-based hardware, creating a shell on a Windows or Unix host where MPE/iX apps run. The infrastructure and surround code changes, along with databases and services like job streaming. A more current solution, from Stromasys, gives modern Intel hosts a Linux cradle, where a PA-RISC lookalike runs existing MPE/iX code, infrastructure and all. Nothing changes except the hardware in that emulation.

CEO Birket Foster said some of his customers have deployed the Charon emulator. A few on the call said the overview was helpful in understanding the options for emulation.

The link to the emulation show is available by following the MB Foster link to its email-collection page. One pass through what the company calls HP 3000 Emulation Options (free signup required) has about 45 minutes of review including slides. The Stromasys information shows up at the 34:00 mark of the show, which includes summaries of EZ-MPE, TI/Ordat, and Marxmeier's Eloquence database — the latter a TurboIMAGE lookalike.

The goal of most emulation is to keep changes to a minimum. Charon does the most complete job of limiting change.HP helped emulation become virtualization for 3000s. Emulation of HP's hardware on Intel came to our community after Stromasys re-engineered code for PA-RISC boot up. HP gave help directly to the company to complete the project after a long pause on HP's part.

Along the way toward explaining how Stromasys became a part of the MB Foster customer experience, there's a comment about the help OpenMPE provided in the effort. After OpenMPE's eight years of lobbying and negotiations, HP in 2010 ultimately made a source code license for MPE/iX available to the market. Seven companies licensed it. Stromasys (called SRI at the time) was not a licensee, though. The code was important to support providers, of course, companies like Pivital Solutions

Adager and Ordat -- the latter the European supplier of the IMAGE wrapper technology mentioned in the webinar, the former the market leader in IMAGE tools -- were among the software development companies, along with healthcare application vendor Neil Harvey & Associates. Pivital Solutions, Allegro Consultants, Beechglen Development and Terix got right to the source code in support of their HP 3000 customers.

The licenses delivered code that couldn't be used in the marketplace until January 1, 2011, the first day that HP no longer offered HP 3000 support services. HP described the read-only licenses as a means for "delivery of system-level technical support."

Whatever the benefits of source code might be for the market—workarounds are a big plus for tech problems on the 3000—emulation in it's least-changing definition doesn't have a link to MPE/iX source.

The link between MPE/iX and the Charon emulation lies in its unique ability to run any code built for the 3000 hardware on Intel systems. OpenMPE opened its quest in 2002 for post-HP 3000 use by hoping for an open source version of MPE. Open hardware arrived instead, using the Stromasys product, an emulation of the iron that HP stopped building in 2003.
