Linux Distro turns PCs into Night-time Clusters

Supercomputing 200

renai42 writes "An Australian security firm is about to launch a clustered Linux distribution based on openMosix that aims to utilise the unused nightly processing power of corporate desktops. Dubbed CHAOS, the distro is able to remotely boot a computer and run it on Linux without affecting the local hard disk. CHAOS is designed to provide dumb node power to a cluster run by existing full-featured clustering distributions such as Quantian and ClusterKnoppix."

I don't know whether it's just me and my uninformed nature, but it occurs to me that switching off these computers would be saving a hell of a lot of money. Rather than using them for something else - which I notice TFA is not clear on, something about a demonstration - why not just power down?

From the Pure Hacking website - Internal on-site penetration testing gives the business the assurance it needs to conduct safely on the internet and with business partners.
It would make a lot more sense if this was only intended for use in demonstrations and testing though, as I can imagine very few companies would feel a need to use this sort of distro on a nightly basis, but for one off activities it may be useful.

Imagine a beo... oh, wait.

there are already corporations out there that turn part of their desktops into a cluster by night.

they have a need for computation power that they can't satisfy and this gives them that at no extra investment besides electricity.

if you power them down then they're doing nothing, your investment just sitting on there. by using them to calculate stuff for the engineering department they're doing something usefull and the return on investment on them gets better.

Although the power savings are something that the world could probably benefit from most large corporations probably have computing tasks that take up a large amount of CPU time, or if they do not could probably profit by providing some CPU time to other companies.
An idea like this definitely makes sense to the corporate world, much like the idea of the 3rd shift in the industrial world. You might as well make use of your down time. I know a lot of the companies that I have been involved with do automatic book keeping at night, I'm sure that using spare CPU time could greatly speed up this process and possibly eliminate the need for powerful and expensive servers.

No.

Most entreprise level desktops have Wake On LAN and PXE boot capability. You send a magic packet to each desktop to wakr it up, and then tell the PXE BIOS to boot ClusterKNoppix via TFTP.

It's not that hard to do, even for lazy sysadmins.

It doesn't sound like you've tried this. W.O.L. doesn't power-up the system when it's been shut-off, so it's really not of any use in this situation.

PXE should be almost all you need... Set the machines to boot from the NIC first, and HDD second, but leave the Bootp and TFTP server off during the day... At night, turn on the netboot servers, and just reboot all the machines. You could either reboot them remotely, set them to automatically reset at a certain time, or just have employees hit the reset button at the end of the day.

It isn't a software thing. It's done in hardware.

You need a network card which supports it as well as a mainboard which supports it (or with built in networking, that usually supports it).

To start it up you send a "magic" package to the NIC which tells it to boot. AFAIK it's just MAC level package with all FF in the data field or something like that. The NIC will then boot the computer just as if you had pressed the power key.

When configured correctly, it works. We do weekly maintenance and nightly installations of software that way. In some scheduled job, all systems get a wake-on-lan packet and they start, and run some install. The users are never bothered with it, unless their systems are offline at that time (e.g. laptops).

Projects like Folding@Home [stanford.edu] already have generated usable results [stanford.edu] . Their FAQ [stanford.edu] answers the question "Who "owns" the results? What will happen to them?":

Unlike other distributed computing projects, Folding@home is run by an academic institution (specifically the Pande Group, at Stanford University's Chemistry Department), which is a nonprofit institution dedicated to science research and education. We will not sell the data or make any money off of it.

Moreover, we will make the data available for others to use. In particular, the results from Folding@home will be made available on several levels. Most importantly, analysis of the simulations will be submitted to scientific journals for publication, and these journal articles will be posted on the web page after publication. Next, after publication of these scientific articles which analyze the data, the raw data of the folding runs will be available for everyone, including other researchers, here on this web site.

Seems to me that what TFA is suggesting is that organizations can use this to gain part-time Beowulf capabilities on machines that could be running Windoze or whatever during normal office hours -- they wouldn't just be giving the processing time away to some random project over the Internet (although that could easily be done too), but using it for in-house projects where an outside connection probably wouldn't even be needed in most cases.

The actual booting could be controlled locally.

Yeah, I'd want to see some security measures in place, like running it in User Mode Linux or something. A dedicated client program like SETI@Home is one thing. A full OS with the capability to fsck with your hardware is another.

which doesn't make them any money.

But it could help save them money. Lots of OSS users have no viable way to contribute back to their favorite projects. Lots of projects could be helped by a vast pool of computing power "on tap". Surely somebody could come up with some interesting applications for a ridiculous amount of free CPU time?

kyle90 (827345) | more than 9 years ago | (#12173887)

I remember hearing about how in the future, we would be able to plug in to the internet and not only access information but also spare processing power. It would be really handy; most of the time you are only using a fraction of the power of your computer (for example, my usage is hovering at around 8%, and I have a movie playing as well as several other applications running), but when you need more processing power, you could get it on demand. Of course, the lag would make it too slow for video games and such, but for some computationally-intensive stuff (video editing, ray-tracing, etc.) it would be perfect.

Re:Precursor to the Grid? (2, Informative)

davedx (861162) | more than 9 years ago | (#12173957)

Not sure what kind of distributed computing you can really do over latency measured in milliseconds. One of the big bottlenecks for today's supercomputers is bus/shared memory access time. I can't really see this being useful for much more than we already do - SETI@Home and so on, where you send packets to be processed and after a few hours the node sends them back.

So yeah not sure if we could ever have a true supercomputer distributed over the net (as it is now, with the light speed as it is!) that's parallel in real time.

ZosX (517789) | more than 9 years ago | (#12173971)

I was just thinking this today as I was watching my desktop grind to a halt as my CPU became maxed out with all the audio encoding I was doing. My file server and a few clients are just sitting around wasting cycled while I could be using them for one off tasks like encoding 20 gigs of wav files along with rendering and such. My desktop is a Windows 2000 machine, and as far as I know, there isn't a way to distribute tasks across the network on such an OS, but, imagine if you could. I know you could whip up some distributed linux stuff, but any box around here running linux is busy doing something as it is and the programs I mostly use on the client end are all windows based...... For example you could queue up a bunch of tasks and leave it for the network to process. Gentoo offers something similar with distcc, where you can do your compiling across multiple machines. Neat. Considering how long it took me to compile a Gentoo system from scratch the last time, I'd say this might be a necessary tool for some people. Especially developers constantly working with large builds. While I think parallel processors and more RAM may be in the not so distant future for me, it would still be super cool to find ways to maximize idle processors connected to my network. I don't know about sharing the CPU with the rest of the world as in a "the net is the computer" scheme, but if I could just some tasks offloaded from my main workstation it would be a great benefit. You are pretty right about the 8% cpu usage. Right now I have a couple of machines pretty much idling away, while I'm still waiting for these ogg files to encode at 3x realtime on a 1ghz machine.

WakeOnLan and NetBoot (3, Informative)

Gollum (35049) | more than 9 years ago | (#12174054)

Here is a suggestion that would allow computers that are not in use to be "co-opted" for use in the cluster.

Identify the PC's that COULD theoretically be used, and collect their MAC addresses. Also, configure them to try netboot first, then fall back to booting from the hard drive.

When you want to perform computations, send a WakeOnLAN packet targeted to each of these computers. Wait for netboot solicitations, then, if you have recently sent a WOL packet to that computer, respond with an appropriate netboot directive, booting the PC into a cluster node configuration, with all details loaded from the cluster director.

Otherwise, allow the netboot solicitation to time out, and the computer will boot into its normal configuration.

Not sure how OpenMosix handles nodes that simply vanish, but users could simply reboot the PC when they arrive in the morning, if the computation is still ongoing. Otherwise, the cluster director could remote shutdown/reboot each node prior to the user arriving at work.

Unused PC's would not consume power, cluster node PC's could be instructed to immediately drop the monitor into Power-save mode, etc.

The cluster director could decide how many nodes to start, or the location of the nodes, to optimise the comms between it and the servers.

An idea with potential, I think!

This CHAOS distribution sounds neat, but with all those machines booting up different OSes at different times it seems a bit complex, possibly almost too complex to CONTROL. (Ah, the old boot Linux on machines over the network but only in the middle of the night trick.)

Does anybody have some example of real (non-scientific nor SETI) example of usage of such a cluster? I want say - what kind of job can such a machine do, especially if generaly network latency/throuhput sucks (standard is still 100 Mbit).

In my departament we have to run some programs that last hours at least 30 times for statistical pourposes. It can be nice to be able to easily launch all this tests in parallel without having to log into any machine in the department.

All my "corporate desktops" are running as a cluster [openssi.org] 24/7.

Initialy the idea was just to simplify maintenance, but doing a make -j 128 kernel_image is quite fun.

This seems quite similar to the concept of Inferno (http://www.vitanuova.com/ [vitanuova.com] from Vita Nuova Limited, except Inferno runs hosted on the operating system (it can run natively). Similar concept, different implementation. I'll stick with Plan 9, though :)

dario_moreno (263767) | more than 9 years ago | (#12174326)

you don't want swap whenyou perform hours-long scientific computations : if the program ever swaps, the perfomance goes down, and since the computer is unattended, the hard disks burns downs in a few hours (happened to me). Many Beowulf clusters are diskless and headless for cost and maintenance reasons anyways.

Converting my old MPEG2 encoded porno movie collection into DivX could really benefit from this.

My ol' PII 300 takes a night per movie basically.

Been going for 60 nights now, only 300 to go.

Could this be a way to get the hole shebang done in a night?

What a wonderous time we live in.

This is approximately how desktop systems should work... As standard in the daytime.

The typical user only makes use of around 1-5% of the power of their machine. That's 95% of your investment sitting doing sweet FA.

So, your OS should have network load balancing built in and when you start a process or sub process it should run on the fastest kit available.

It's very simple to tack this kind of functionality on to Unix (including Linux here). Mozix does it in a rather nicely integrated fashion, but you can add something like SGE and some wrappers to make any network of Unix boxes act as a coherent system with *very* serious horsepower, or Wattage since we're in the 21st century.

billysara (264) | more than 9 years ago | (#12174374)

There is a package called Condor [wisc.edu] which runs as a job-schedular under windows or linux. It can either run on dedicated machines or as a seti-at-home screensaver type idea to use idle machines. Works very nicely and can really harvest a lot of idle PC's across companies or campuses...

Sure, leave your entire network wide open... (0)

Anonymous Coward | more than 9 years ago | (#12174295)

Most clustering software provides little or no security -- its not like OpenMOSIX is going to switch to an AES network protocol at the cost of a 90% performance hit. So now imagine every workstation on your network, from HR to the executive staff, completely accessible to remote jobs, and each of these "jobs" could easily access the drive in the standard fashion. You might as well share out the system partition read/write to the network...

ajs318 (655362) | more than 9 years ago | (#12174486)

I was thinking about "cheaper than free" software -- a Linux distro that turned your broadband-equipped computer into a cluster node while idle -- a couple of years ago. All that computing power going to waste ..... But I couldn't find a way to build a business model around it -- it was just too hit-and-miss for any task I could think of. What data is there that can be batch-processed in a completely non-time-critical fashion, and is so non-security-critical that it can potentially be shown to thousands of strangers?

You could encrypt everything {and that would go some way to prevent tampering with the returned results}; but then, if you're going to process encrypted input and return encrypted results, that will eat a lot of your processing power. It's a bit like putting a V8 engine through a three-speed automatic transmission ..... in the end, it won't really do anything an old transverse four and man-tran can't, apart from drink fuel and leave you wondering why you bothered.

There is a possibility of "inter-cycling" in certain, limited settings {using corporate desktop machines which typically have only a few gigs of apps and data for RAID-like backups of servers springs immediately to mind}. But outside of these circumstances, switching off when not in use and recycling when done with are the best ways of avoiding waste. There is often plenty of life in a used machine if it doesn't have to run a bloated graphical desktop environment and numerous accessories {wanted and otherwise}. And at least used PCs are something you can store up till you have enough of them to do the task you want to do ..... remote CPU time and bandwidth are only available for fleeting moments.
