32 and 16 bit. The boot loaders used and FreeDos required incorporation of 16 bit support. Monumental pain. We don't see 64 bit support being problematic though.

Well, probably not *exactly* if there's enough novel in there to patent, but, yeah, JIT instruction-stream-translation with caching of commonly-reused fragments was the way ARDI was emulating 68K Macs on Pentiums back in, oh, 1996 or so. That would (of course) be a better way to cut your overhead, because if you have a long sequence of s390x instructions mapped (nearly 1-to-1) to a long sequence of x86(_64?) instructions, then you only take the "wrapping the registers and shifting the arguments around" hit once per chunk, and a lot of x86 executable code is a) boilerplate and b) common in most executables produced by the same compiler, so this could actually be a very big win. Does z/VOS do x86_64 or just 32-bit x86? Actually, can you list which x86 extensions are included in it? Or do I need to wait for release to find out. Adam
Re: Nice idea in blog: Should we toss x86 architecture - NOT.
Apologies for not responding to this thread in a more timely fashion. I had a flood of emails after the initial post. Speed OR Portability Adam is closer than he knows about the approach we have taken on z/VOS. First, he is right when he guessed "almost-certainly assembly". We have tried both QEMU and BOCH and you can forget your name before the target OS completes IPL in our current environment. This is not meant to be a criticism. Both of these systems were written for portability rather than platform specific speed. He is also on target about the instruction mapping. Obviously the closer you get to a one to one instruction relationship the better the performance. Pipeline/Instruction Overlap Making the instruction stream pipeline-friendly has been another consideration with z/VOS. David Bond gave a great presentation (Share Session 8192 in August 2006) on this so I leave it to you and Google if you are interested. Single Pass Translation For those of you that think emulation of x86 would be a bad idea, we agree. z/VOS translates guest OS code during initial execution. Code fragment storage, lookup, disposal and reuse for primary and sibling guests are addressed in a patent application. Suffice it to say that we don't interpret or emulate massive amounts of x86 code for use 2-n. z/VOS Development Environment Mantissa has a FLEX development environment that redefines and enhances the definition of "slow". We have two copies of VM operational at all times. One of the VM system supports z/OS and VSE development. The other system is dedicated to z/VOS development. Because Adam mentioned FreeDos, I will give this point of reference. Under z/VOS FreeDOS IPLs in 1 second with all debug logging interfaces enabled. After the IPL, it is split second responsive. --. .- .-. -.-- Gary Dennis Mantissa Corporation On 7/25/08 11:28 AM, "Adam Thornton" <[EMAIL PROTECTED]> wrote: > On Jul 25, 2008, at 8:48 AM, McKown, John wrote: >> >> Somewhat like BOCH?

Apparently it now does x86_64 and can run Vista. It will be interesting, once Mantissa is released, to do a speed comparison of it versus Bochs, since both appear to be, essentially, x86 emulators. I haven't been able to build it yet; it, at the very least, requires X libraries, so I need to build a dev box with the appropriate libraries. And of course it's going to bespecialto run it on, ahem, a Flex box running in 64-bit mode on 32-bit (Intel) hardware, which is what we have in-house. Adam

If so, then unlikely that CMS would run on "cell blade engines", and emulation not required.

Good luck, Gary. I do hope your organization can pull this off. VM-ers need more employment possibilities:-) I gather from some of your previous posts to this list that your Windows support software, z/VOS, is in fact a sophisticated CMS-based application, that is a user would log onto a CMS user id to start his Windows systemis my understanding correct?

Re: Nice idea in blog: Should we toss x86 architecture
When I read this post I sat at my machine for about 2 minutes trying to figure out a good way to respond to your question. In that 2 minutes nothing on my screen changed except the seconds field on the time box. Everything else in the video buffer stayed absolutely the same during that wait. It is highly unlikely in a business environment that everyone would run a compute intensive application such as a screen saver to run on 3000 virtual machines simultaneously. A screen screen saver would run on the appliance that supported the RDC environment (and that actually had a screen to save). Again, most desktop machines don't actually do enough from a task activity and graphics standpoint to create overwhelming overhead. --. .- .-. -.-- Gary Dennis Mantissa Corporation On 7/22/08 1:44 PM, "Romanowski, John (OFT)" <[EMAIL PROTECTED]> wrote: > How can the z handle "3000 copies of Windows" all running a graphic user > interface (cpu-intensive) ? > > > > This e-mail, including any attachments, may be confidential, privileged or > otherwise legally protected.

Re: Nice idea in blog: Should we toss x86 architecture
I think that even 10 copies of Windows, especially in an emulated environment, will eat up enormous amounts of zSeries CPU. Add in the license costs from Microsoft, and I'm not sure it makes any kind of financial sense. But I like the idea. I plan to watch this develop with my eyes out on stalks. :) -Paul On Jul 22, 2008, at 1:53 PM, Rich Smrcina wrote: My guess is that all of the GUIs won't be actively doing things all at the same time.

I know that I wouldn't be wanting that. Most likely this would be to run things such as MS SQL Server, MS Exchange and other "server" software. Not an end-user GUI session.

Re: Nice idea in blog: Should we toss x86 architecture
It sounds like Mantissa is on the road that I am interested in. Specifically, I would like to see IBM incorporate the capability into z/VM to dispatch virtual machines on disparate architectures made available via co-processing capabilities, such as those currently provided for encryption, and where communication between the mainframe and the co-processor is handled using the SIGA (Signal Adapter) machine instruction. Of course, I would like to see the SIGA instruction documented in the z/Architecture Principles of Operation publication. I can envisage a z/VM machine running z/Linux, z/OS, z/VM (2nd level), z/VSE, and thousands of copies of Windows. We can hope that the version of Windows will be more stable than Windows Vista. Moving that kind of instability into z/VM is not particularly attractive. Otherwise, on a conceptual basis, it opens up many possibilities. John P.
