Hi The real problem it seems to me, is one of philosophy rather than what is practically possible. The use of Ubuntu as a carrier vehicle has enabled a lot of people with minimal Linux knowledge to use EMC. As Kirk said, if a better technical solution were used at the expense of usability, that would impact upon the user base unless someone could be bothered to wrapper it for the uninitiated (which is the overwhelming majority). There should be no reason why the user could not have a choice of kernels from the distro at install time, one for SMP another for UP say. That immediately would answer a lot of problems. I personally do not like the later versions of Ubuntu and strip it out and use a light display manager and windowing system, because I hate the bloat and long initialisation time of Gnome and KDE. I have been doing a lot of rtai kernel building recently. Initially to test the effect of different configs on a quad core MB latency and more latterly to try to build a very light Debian based EMC distro, suitable for old machines. In the course of this I found that EMC runs well on a single processor build of both Lenny and Squeeze and will install on both new and old machines. I currently use a Debian Lenny build, not Ubuntu to run EMC. The longer term problem is that EMC has created a dependency upon a version number of Ubuntu to bring the latest version of EMC to the average user. It does not matter how many times users are told that you can run the latest 2.6 RIP on a Ubuntu 8.04 installation. Because it involves the unknown territory of compilation, they are not interested, all they want is another Live CD release that installs everything for them.

From my experience - those people, who are unfamiliar with EMC, are unfamiliar with Linux. The fact that EMC is running on Ubuntu has helped to convince those people I have dealt with that it is worth trying it, because it is working out-of-box. Hobby users have time to spend on compiling the software and do other things. My customers can be considered as industrial users and they like the fact that no special linux knowledge is required to run EMC. A simple system can be set up within hours, completely restored on different PC hardware within 1 hour - just reinstall OS and copy config files. If additional installation of customized kinematics module or some realtime component is required, it adds just a few minutes to overall time.

I use quite a few installers - the Debian one is one of the best. Of course if you have brandnew hardware without driver support you can have problems - as is true for all the Linux distros.. There are Debian firmware packages (they supply the binary heaps in /lib/firmware) in case you are using some proprietary firmware. Just isn't a problem these days and particularly so for the things in EMC2. Having a rock solid system is important for folks running EMC2 - There are many cases where bleeding edge support means a less stable system - not something I want on a machine tool. A lot bugs get fixed in Debian first. The fixes pass through experimental - unstable, testing then stable and it is possible to pull code in from unstable to a stable system if need be ( Ubuntu is mostly a mix of testing/unstable Debian packages anyway). (There is also way to pull in Debian packages to Ubuntu). The one thing that Ubuntu offers is paid support - but the comments I've heard from people that have used it say it is better to just search mailing lists.. There are many that are now saying that mint (it is also based on Debian) is displacing Ubuntu as the best desktop ( there is now a branch of mint that goes straight back to Debian to avoid some bugs) - , but I would say the differences are really small - most distros are running pretty much the same code - the important issue for controlling a machine is stability - and Debian is the stability king with the older, time-tested, and debugged code - a good thing for machine control.

Jack We've had variations of this discussion before. My principal question is always, what do you want your real-time EMC2-equipped computer to do? If it is intended solely to control a machine, then most of Ubuntu is unnecessary. Others have posted to the Wiki their successes in bringing EMC2 to minimalist Linux environments, and we could go that route. Indeed, I'm planning to do that myself once I get around to finishing my real, headless controller (as opposed to my bench-test controller). Instead of starting with a distribution packaged by someone else, we could create one ourselves, starting with Linux From Scratch (LFS), resulting in the absolute minimum environment needed to build and run EMC2. To my mind, for controllers there are only two reasons for thinking about upgrading the O/S: 1) a new version of EMC2 with features I want requires it or 2) a new motherboard/CPU/peripherals-combo to replace an old one requires it. Upgrading for just the sake of getting the latest flashy desktop seems ludicrous. On the other hand, if your EMC2-equipped computer is intended to support Internet telephony, browse HackADay.com, run all your favorite CAD/CAM applications, keep the books, play music videos, etc., and, oh-by-the-way run a machine tool (I think this is the wrong approach, but that's just me), then you're likely to want to start with a full distribution like Ubuntu, so why not stick with Ubuntu for as long as possible? The number of applications that are supported in Ubuntu is staggering. I don't think any of the other distributions are immune to the pressures of the marketplace (even with free software there's a marketplace, it just has a different reward system) and won't get enamored of Unity or their own version of a touchy-tablet desktop environment. We can strip the distribution down if we like, or, instead of subtracting from the full edition, we could add to the server edition. Whatever. This kind of remastering used to be very hard but it's gotten easy in recent years. And if Ubuntu goes completely off the track, there are other, less popular distributions so similar in the technologies EMC2 depends on that the transition would be almost effortless. Frankly, if I wanted to lie awake at night, I'd choose to worry about the teams developing real-time extensions to Linux in the face of rapid changes to the Linux kernel or about the future of AXIS as both desktop environments and windowing systems evolve.

Re: [Emc-users] Next distribution after Ubuntu 10.04 LTS is no longer supported?
There's no fixed answer to your question. If there is one, it's this: Whatever members of the community step forward to provide though for the last 4 or so years another answer has been Each Ubuntu LTS release, sooner or later If it really tickles your fancy, and you have hardware that is compatible, then you can still download the emc 2.1 releases for Ubuntu 5.10 breezy badger and they'll work just as well as they always have. On the other hand, we sometimes find that we cannot continue to support old distributions without making bad compromises (for instance, hostmot2 won't work on Ubnutu 5.10 because the realtime kernel of that vintage lacks support for 'request_firmware()', but being able to choose a firmware at runtime is a very important element of hostmot2). Not to mention that Ubuntu 5.10 is so old that nobody is offering up patches to keep emc2 running on it. It's really when there's no longer an active advocate of a previously-supported operating system release that we stop trying to make new versions of emc2 work there. For that reason, there's a (fairly slow) requirement to upgrade to new distributions when upgrading to new feature releases of emc2. But this thread is not precisely about running new emc on old distributions, it's just as much about the idea that each new version of Ubuntu is becoming less suitable for running realtime software, or for running on low-end hardware. This may be true, though the Ubuntu developers are probably making very reasonable decisions if their goal is to create a good desktop and server distribution. For instance, we have seen that many accelerated OpenGL drivers lead to unacceptable latencies when the requirement is sub-10µs jitter. But this latter requirement is totally irrelevant to a standard desktop system. There's no reason that Ubuntu shouldn't make accelerated OpenGL a requirement in their new desktop systems, but that item alone might make emc essentially broken for a large swath of its users. As I see it, what we have gained from Ubuntu in the past is a system that: * is usable both as a standard desktop system and as a CNC control (at the same time!) * uses debian-based software packaging * receives security updates for 3-5 years * works on a fairly wide range of machines * can run live or install to a hard drive * can easily be set up as a development environment for emc2 * fits on a single piece of standard CDR media I would be sad to give up any of these features (though Ubuntu 12.04 will reportedly give up on fitting on one CD, so already we stand to lose on that score) There have been a few efforts to make a non-Ubuntu-based distribution for emc2. I recall two, one based on Puppy Linux and the other based on DSL (Damn Small Linux). However, these failed in many respects. The worst aspects were that they did not have security updates, and that they were difficult (or impossible) to set up as as emc development environments--building a new version of emc2 (or anything else) involved building a new CD image on a regular Linux system, and upgrading an installed version involved deleting all customized files in the system including emc2 configurations. They were also nearly useless as desktops, because they only included non-standard or very old web browsers. For these reasons, they are not of any practical use. On the other hand, contributor Acemi has in the past posted very thorough instructions on our wiki that explain step by step how to get emc2 running on various versions of Debian. Debian has many of the features we want (software packaging and updates) and also has leaner installation requirements compared to Ubuntu's standard desktop. If you want to install emc2 on a low-spec machine, then my recommendation would be to learn enough Linux to follow these instructions (which unfortunately have not been updated since before Debian 6.0 was released, so now they're a bit outdated). This hasn't even touched on the trade-offs inherent in this little bullet item: * works on a fairly wide range of machines Two major trade-offs are: SMP vs UP and 32-bit vs 64-bit. For our distribution based on Ubuntu 8.04, we opted for UP and 32-bit and later on offered a SMP 64-bit version (without corresponding live CD). For 10.04, we opted for SMP and 32-bit--and based on the lack of feedback about the 64-bit version, we didn't offer a 64-bit version again. The SMP version actually works on single-threaded CPUs, but requires a hardware feature called APIC. Information on the internet indicated that Microsoft made APIC a requirement for receiving the Windows logo in 2001, so we judged that this would not be problematic. However, the difficulties encountered by our users indicate that this may have been the wrong decision. In 2012, what decision should we make?

In the long run, I think it would be MUCH better to target Debian stable. There is no need for most of the bleeding edge issues that come with Ubuntu for an application like EMC. The stable dist of Debian is really stable and used by many as servers. The only things that change have to do with security issues. For a 'live' edition, Debian live could be tweaked with a realtime kernel.

Re: [Emc-users] Next distribution after Ubuntu 10.04 LTS is no longer supported?
Another option to consider is not using Unity or Gnome3 but maybe LXDE or XFCE instead. Both of these are quite adequate for a machine control and general desktop use. I used Xubuntu on my router table because it took less resources, and it works just fine. Another thing I thought of last time and it may be a good idea still, is to have a UP kernel and a SMP kernel and people could chose the one that works best for their computer. There may be a way to have the liveCD install pick the right kernel, but if not at least it could be an option in the repository for after the install. I'm willing to help work on the next release again btw if I can carve out a little time.

Andy, I was not trying to suggest EMC2 is bloated, but with the newer releases of Ubuntu, I have heard reports that they are becoming bloated. My thoughts were that EMC2 is with a fairly trim distribution (Ubuntu 10.04LTS) and should make sure the partner we pair with is similarly endowed. Boy, I'm glad my wife isn't saying that about me.

On Wednesday, November 23, 2011 08:23:43 PM Jack Coats did opine: I know EMC2 doesn't do anything but Ubuntu LTS as it's 'official' supported distribution. On several other lists I have noticed the complaints about the Ubuntu Bloat and moving to Unity and things not working. Have we, as a community or even just developers, thought about now to go to a 'less bloated' distribution? I do like the idea of the LTS (Long Term Support) part of distributions. And moving from any distribution to another I have always considered a pain. But I could support moving if we can find another 'long term supportable' option where this community doesn't have to support the OS also. Any ideas? Thoughts? Concerns? I am considering moving this box from pclos to centos-6, but as a kde person, the kde in it is one of the half broken 4.3.5 hacks, probably with its bigger warts covered by the parent RHEL-6 patches. This theoretically gets us nearly 5 years of LTS. The downside is that while security patches will follow the RH releases by 1-2 weeks, version numbers are largely frozen since RH has a habit of backporting patches but not a whole new release. But OTOH, it is at least as fresh as 10.04 is, and likely a heck of a lot more complete than my pclos is. I am always finding something that needs 2 or 4 libraries pclos doesn't supply so I can't build a newer, 10,000% improved digikam for instance. Ditto for wpa_suplicant which in the pclos version is a miserable, time wasting failure. For 10.04, it Just Works(TM). That distro runs at a bit over 7Gb, takes two dvd's now. Its current kernel is 2.6.32-71 in the 64 bit version. This is still being actively supported on the Linux-Kernel Mailing list as a long term supported kernel, and should be fine on any hardware more than 2 years old. AFAIK, no new 'long term' kernels are about, and likely won't be till 3 months or so before the RHEL-7-rc1 release is defined. Since 6 is pretty fresh, that likely is 2 years plus down the log. I ran a 2.6.32 kernel here for a while, but pclos changed to the 2.6.38 about 9 months back, with the BFS scheduler enabled in some builds. How that would co-exist with RTAI, I have no clue, but to the desktop user, bfs is one heck of an improvement in the feel. Thanks for the responses. ...

Jack What has me nervous is my recent experience of upgrading from 8.04 to 10.04 and having some of my long trusted motherboards not work or have terrible latency, with the usual fixes having no effect. There may be solutions in the wings, but I really don't enjoy having to search for or wait for a fix every time the operating system gets upgraded, especially if most (or all) of these upgrades have absolutely nothing to do with EMC2 or RTAI.

Re: [Emc-users] Next distribution after Ubuntu 10.04 LTS is no longer supported?
I'm not saying that the 10.04 is bloated, but some of the folks that have moved to 11.04 or 11.10 locally have noted several 'broke as designed' items and have complained about bloat in the newer versions as well as the new Ubiquity user interface. I am guessing 12.04 will be the next LTS version. I am not complaining, just wondering what our outlook for the future is and if there are any suggested changes. Trying to be a bit proactive and forward thinking. Historically I have seen software enlarge to meet the capability of the hardware it runs on. Using its features is OK, but leaving some of the capability for other software to use (like EMC2, CAD/CAM packages, etc) rather than trying to soak it all up in the OS and support software is good too. ...

Jack We've had variations of this discussion before. My principal question is always, what do you want your real-time EMC2-equipped computer to do? If it is intended solely to control a machine, then most of Ubuntu is unnecessary. Others have posted to the Wiki their successes in bringing EMC2 to minimalist Linux environments, and we could go that route. Indeed, I'm planning to do that myself once I get around to finishing my real, headless controller (as opposed to my bench-test controller). Instead of starting with a distribution packaged by someone else, we could create one ourselves, starting with Linux From Scratch (LFS), resulting in the absolute minimum environment needed to build and run EMC2. To my mind, for controllers there are only two reasons for thinking about upgrading the O/S: 1) a new version of EMC2 with features I want requires it or 2) a new motherboard/CPU/peripherals-combo to replace an old one requires it. Upgrading for just the sake of getting the latest flashy desktop seems ludicrous. On the other hand, if your EMC2-equipped computer is intended to support Internet telephony, browse HackADay.com, run all your favorite CAD/CAM applications, keep the books, play music videos, etc., and, oh-by-the-way run a machine tool (I think this is the wrong approach, but that's just me), then you're likely to want to start with a full distribution like Ubuntu, so why not stick with Ubuntu for as long as possible? The number of applications that are supported in Ubuntu is staggering. I don't think any of the other distributions are immune to the pressures of the marketplace (even with free software there's a marketplace, it just has a different reward system) and won't get enamored of Unity or their own version of a touchy-tablet desktop environment. We can strip the distribution down if we like, or, instead of subtracting from the full edition, we could add to the server edition. Whatever. This kind of remastering used to be very hard but it's gotten easy in recent years. And if Ubuntu goes completely off the track, there are other, less popular distributions so similar in the technologies EMC2 depends on that the transition would be almost effortless. Frankly, if I wanted to lie awake at night, I'd choose to worry about the teams developing real-time extensions to Linux in the face of rapid changes to the Linux kernel or about the future of AXIS as both desktop environments and windowing systems evolve. Just my 2 cents worth.

Just because I've been looking at the EMC2 documentation lately, I've begun to wonder about some of the statements made about minimum requirements for CPU speed and RAM size. Some look suspiciously old. Have we tested these claims lately? I was thinking about using virtual machines to try installing and running EMC2 (in simulator mode, of course) with different memory sizes, but realistically I can no longer test at slow CPU speeds like the 400MHz PII/PIII claimed on the Wiki or the 700 MHz x86 claimed in the Getting Started doc.
