Grab A Piece Of Big Blue's Big Iron
Alowishus writes: "IBM is going to make one of its high-end zServer mainframes available for free to the public for development and testing of Linux applications. It has 10 CPUs and 2.1TB of storage, and will offer TurboLinux or SuSE distributions set up as virtual servers. It's expected to support about 1,000 simultaneous users." However, hold your horses just a bit: Registration is not yet open, the accounts are good only for a limited time, and the site lists other conditions details, though none sound onerous. Among other things, "once a user is registered and approved to access a LCDS system, a user is required to have direct Internet connection, via a Telnet and SSH client." Though there have been other free sandbox accounts, having an account on an S/390 would be sweet, eh?
I think this is IBM's argument: Linux and Apache have become de facto multi-vendor marketplace standards. It's more effective to adopt and adapt this giant body of work than it is to bear all the costs of a specialized big-iron operating system and web server.
From the Free Software point of view: a quick empirical view of the world shows that corps and govs want big iron, and want some software to run on it. I believe that the world is a better place when all software is available under some kind of open license, not just the bitty box software that you care about. What if I wanna teach myself how big servers run 1000 separate system images? I start reading the arch/s390 directory in the linux kernel source. Or I read a book by a teacher who has access to arch/s390 source and can use that knowledge to teach me.
Computer programming is more than those 10-week class projects in undergrad school. We have millions of lines of "prior art". The GPL license and the BSD license are the most effective ways on the planet to make that prior art as accessible as the primary literature in disciplines like chemistry. That's important if big-iron programming is going to be an open competitive field, not limited to employee/serfs operating under NDA's. (Insert return-of-medieval-guilds rant here).
(Maybe you think the world would be a better place if nobody had a computer that big. I think that would be a Luddite opinion. The fact is, lots of organizations already do, and I'm happier if they are running Linux rather than a closed-source OS like AIX or Solaris).
No, just those sunglasses that block out harmful blue light..
No no, some people do miss a thing here..
/root /usr, 128MB RAM, disk space etc..
/usr/local and start installing/erasing stuff, you'll have to reconsider other users when you running you wild intense-use-of-processor app..
What IBM will give you is an ENTIRE VIRTUAL MACHINE! - not just a very limited user account - but a full Linux virtual machine - with
On Compaq machine you just get an account - you cannot go to

I uploaded some homebrew benchmarking software to it. The memory bandwidth seems amazing. Compared to a reasonably high-end Intel server, it has about 10x the memory bandwidth. Either that, or lots and lots of L2 cache. But I'm sure I wasn't the only one on the system, and the tests consistently showed almost 10x the throughput of Intel.
The test was simple: take a range of memory of X megs, and write a random char to it. Time how many can be done in a quarter of a second, extrapolate MB/s from that. I get almost the same numbers if I use 10MB chunks as I do to 1MB chunks. Good shit here.
Single CPU performance isn't much different, but that wasn't the point. The systems could also be configured to give my account access to multiple processors.
If I started my own hosting company, I think I'd definitely use one of these babies.

Great! Let's all just shout foul to IBM. How dare they give access to a computer for free? Bad bad IBM! It should be GPL! No! They should also give free T-shirts!
SourceForge is a great contribution but don't use it to put down other gifts. That's greed.
This is great marketing for both IBM, and Linux. First off I think this is more of a marketing tactic than IBM trying to be helpful to any developer. By having thousands of developers do their thing on the machine, they could always turn around and pimp the results as both an IBM, and joint Linux effort which is pretty cool for Linux marketing...
However on the flip side of the coin, I hope the developers rush to fill these slots as opposed to some troll who's going to use those accounts for silly shit like h4x0rf00.c programs they wanna throw up, or uneccessary other shit...

What a waste to spend resources on opening an S/390 considering what they could be used for.
What about taking 10% of that BILLION and earmarking it to support open source developers??
Where were they when Eazel tanked? What about the folks at SourceXchange? Are they doing anything more than thinking about marketing, pr facetime, and beating their own products to death?
I'd much rather see some of that money go to supporting hookup of an IBM microdrive to the Agenda, or a zillion other things, than this.
IBM should earmark 0.05% of their budget (that's still half a million bucks right?) to - guess what - pay great open source based developers and designers to build a site that would try to get feedback from the Linux community, including developers, users, and purchasers, as to what sort of things we'd like to see. It might even save them some marketing money. IBM's done some good things but this is not the top priority if they are serious about spending that money on open source.
If they believe Linux gives them value for the money, then they ought to be willing to put money down to get high quality engineering and design talent to work on projects which IBM could share with the open source community and continue to improve Linux.
One really cool thing they could do is endow a chair (or 10 or 20) like the year off from school which Perl mage Damian Conway received from the community.
But what might seem like a grand experiment is also a shrewd marketing move by IBM. None of IBM's server competitors--such as Sun Microsystems, Hewlett-Packard or Compaq Computer--has offered similar programs.
ZDnet seem to be avoiding the fact that Compaq have their huge TestDrive program. They let anybody (currently)access:

I agree that the limited time is good for the 'testing' users who just want to know how it feels, but I doubt they will appeal to someone who would like to do a serious work with such conditions.
If programs would be read like poetry, most programmers would be Vogons.
What will you need if you want to try Windows out? A Beowulf of Crays?
This is a great oportunity for people that want expernce with a mainframe, one thing that linux runs well on. Its a learning experence much akin to the the hacker ethic, but it is also a blatint plug for ibm.

I expect that the majority of work allowed by Big Blue will be architecture porting and testing (eg, x86 to S390), rather than development from scratch. There of course will be (I expect) some products that may wish to exploit the Linux-to-z/OS (the OS formerly known as OS/390, MVS, yadda-yadda) functionality that is soon to come (why go over the network from a logical Linux machine to a logical z/OS machine when you can go cross-memory?), and these will be developing some code from the gound up. But I can see that a lot of software currently running successfully on x86, PPC, etc (commercial or not) needs to be tested on 390 to officialy "support" it, and, let's face it, not many people have easy access to a 390 machine, let alone a 390 machine running Linux!
:-)
This is IBM's way of getting as much existing Linux software as possible to list 390 as a supported architecture. There's a lot of support-contract related money to be made by distributions in this areana....if a company has already shelled out on 390 hardware, they are hardly going to go without a software support contract for their Linux Distro.
Having said all that, I believe that the porting effort is negligable for most user-level applications, but of course, you would like someone to actually test their software on the architecture before assuring you it works there, wouldn't you?
Gollo.
