Ask Slashdot: Best Use For a New Supercomputing Cluster?

Unknown Lamer posted about 3 years ago | from the reclaim-heat-for-silicon-diner dept.

Networking 387

Supp0rtLinux writes "In about 2 weeks time I will be receiving everything necessary to build the largest x86_64-based supercomputer on the east coast of the U.S. (at least until someone takes the title away from us). It's spec'ed to start with 1200 dual-socket six-core servers. We primarily do life-science/health/biology related tasks on our existing (fairly small) HPC. We intend to continue this usage, but to also open it up for new uses (energy comes to mind). Additionally, we'd like to lease access to recoup some of our costs. So, what's the best Linux distro for something of this size and scale? Any that include a chargeback option/module? Additionally, due to cost contracts, we have to choose either InfiniBand or 10Gb Ethernet for the backend: which would Slashdot readers go with if they had to choose? Either way, all nodes will have four 1Gbps Ethernet ports. Finally, all nodes include only a basic onboard GPU. We intend to put powerful GPUs into the PCI-e slot and open up the new HPC for GPU related crunching. Any suggestions on the most powerful Linux friendly PCI-e GPU available?"

Start with the cheapest backend that'll get the system up and running, then use your supercomputer to mine Bitcoins for a few days, then use all the money you'll make to buy the InfiniBand backend (you'll probably have enough money left over to buy Monster cables to hook everything up).

Re:Lost some funding? (0, Troll)

webmistressrachel (903577) | about 3 years ago | (#37392198)

Monster cables are only worth the investment for speakers and line-level / mic stuff (i.e. analogue signals). Having a Monster-cabled computer network would be no better than having the generics of the same cables.

We all know this - and MP3 and the so called "average listeners" (people who buy Britney Spears) have ruined the hi-fi industry with their cable sarcasm. Yes, MP3 will sound crap on a Monster cable, too. But 44.1KHz 16-bit sound, converted to analogue in the transport and sent to the amp via line leads WILL benefit from Monster / premium cables, as will speaker cables of any kind.

Maybe the mods are a little more aware than you of the engineering and scientific FACTS about Monster Cable. Some things that you said:

Monster cables are only worth the investment for speakers and line-level / mic stuff (i.e. analogue signals). [...] But 44.1KHz 16-bit sound, converted to analogue in the transport and sent to the amp via line leads WILL benefit from Monster / premium cables, as will speaker cables of any kind.

are, I'm afraid, complete nonsense. Counterfactual, in fact. And yes, there's real science to support that. Let me gloss over it...

A 44.1 kHz sample rate before the DAC means the maximum frequency component the cables need to handle is 22 kHz. (This is due to the Nyquist limit, as in the Nyquist-Shannon Sampling Theorem.) 22 kHz is low. Really low. Practically any old piece of wire can carry audio frequencies with perceptually flat response across the audible range and nearly no loss as long as the cable lengths are as short as they are in a typical home stereo system. The only thing you need is large diameter wire for your speaker cables to ensure they're very low resistance so that the higher currents involved in powering a speaker don't cause resistive loss in the cable.

As for low-power line level signals (such as CD player to amp), the most likely source of problems is actually ground loops, where the source equipment has a different ground reference than the destination. (A lesser concern is interference.) The pros don't solve this with stupid Monster Cable, they solve it by using pro equipment with balanced (differential) signaling, which both eliminates the need for the source and destination to have a common ground and provides some noise immunity.

For home stereo systems, however, making sure that everything is grounded to the same point (3 prong plugs all plugged into a single grounded power strip) is generally good enough, and noise is rarely (if ever) a significant problem.

He won't even have GPUs initally.
CPU mining is about as productive as mining for (physical) gold with a toothpick.
GPU mining is slowly becoming less viable since people have rolled out FPGA miners.

And if anyone ever decides to go full-blown ASIC, mining will be dead for 99.9999999% of people.

More on point: This seems like a retarded cluster if you haven't built it with GPU shit initially in mind. It's not like CUDA/STREAM/DirectCompute/OpenCL are hard if you've already got the highly parallel algorithms and workloads in the first place. Dude's got 1200 boxen that could be outdone by 40 GPUs in 10 boxen for the vast vast vast majority of workloads. The time saved in setup and management, as well as the cost with regards to the communication backplane, power delivery, etc., could easily pay for a few programmers to rewrite any legacy code to be GPU-ready.

And with AMDs 7000 series coming out, the energy cost / performance would be a trifle. A trifle! []

Two weeks away and still at the “thinking of cool shit to use it for” and “picking out hardware” stages? How does that even happen? Is this some kind of tax scam to burn as much money as possible?

I get that the submitter already have a primary use... but I imagine if I was ever given that kind of budget I’d probably have to account for every CPU cycle every hour of the day (especially since I’m a programmer and should have no business with something like this ;p). I can’t imagine a budget for something like this comprised of “and hopefully we’ll be able to recoup the millions of dollars by leasing it out to some TBD people”.

Also, the first person to mention bitcoin as an option gets to have their teeth rotated. I’m not joking.. we will find you..

Re:I call Shenanigans!!! (2, Funny)

Anonymous Coward | about 3 years ago | (#37392336)

Yes, it probably is a tax scam. It is now the US Federal Year End. Someone wrote a really good funding proposal and got it approved to get money for a HPC cluster to do *something*. Doesn't really matter. The grant application will have focused on broad ideas like # of cores and what not and not the details. A bit surprising that the network wasn't spec'd because that is such a major cost item, but whatever, maybe the grant application's work loads are not network bound.

So, now that the money is approved the task to build the thing falls to the inexperienced IT group who make all kinds of dumb choices, then will claim they are massively over worked/underfunded trying to get the thing to run and end up with shitty performance and a lot of wasted time and money. Oops. Your Money At Work.

The system you spec'd should be around the 250TF range, if you set it up properly with QDR IB and do all the work to get MPI optimized. If you are good. The correct way to design the network is to match a 36 port IB switch with 18 servers, and then correctly spread the resulting 1200 uplink ports across a pair of 686 port core switches. The cost of IB cables alone will be shocking and you'll regret not using a HPC blade server arrangement for this.

Considering the questions you are asking, you should have gone with an HPC focused integrator that could provide the full system for you. 4 GIGE's on every box? Waste of money. The IB equipped blade designs from SGI/Bull, etc are very nice, space and power efficient and much more cost effective. They even come with a pre-integrated and tested OS ready to go, working boot over IB and other long term cost saving features.

Gosh I hope you bought a few PB of HPC focused storage as well, otherwise you won't find anyone who can even use your machine for their problems.

Re:Ummm two things (2, Interesting)

You clearly have no idea what you're talking about. I was just part of a million-euro EU project consisting of a large partnership of universities and companies. Given the fact that none of them ever did anything, my professor gave up and defined the project on his own.
I coded the entire project on little more than minimum wage while I was also attending classes. I managed a couple of helpers who did web design and documentation, and dealt with the rest of the partners on my own, even interacting with fancypants EU higher-ups at some point. I was also in charge of administrative work such as financial reports. I dealt with the university accounting department directly as well as their administrative staff. I booked flights and physically walked over to the traveling agency. I represented the project at every single conference where it was demo'ed. As part of its end goal of meeting an audience target of a few thousand people, I took the initiative of aggressively promoting the project and was met with huge success.
The vast majority of the cash was spent on people who did absolutely nothing other than throwing one or two opinions in the 18 months the project lasted. Our university's share was used to buy new chairs and tables and repaint the walls etc.

Anubis350 (772791) | about 3 years ago | (#37392426)

1)You haven't been to any computer conference (like, say, SC) have you? or worked on a supercomputer? Most supercomputers these days are clusters, and hell, one of the most common interconnects is still gigE, not even 10gigE, though that's slowly changing (check the top500 stats if you don't believe me, but I've been at SC's top500 announcement every year for the past 4, and it's been mentioned each time. For that manner I run jobs on a gig based cluster everyday, and for many types of work it's not necessarily a hangup).

2)I'm going with "article is fake", no-one commits the resources to spec, build, and power a cluster of that size without a projected use. You should see the hoops you have to go to to spec machines a fraction of the size ::shudders::

Re:Ummm two things (2)

Sycraft-fu (314770) | about 3 years ago | (#37392600)

They may call them "supercomputers" but in my mind that is mislabeling things. They work for cluster operations, where there's not a ton of inter-node communication and no need for access to memory outside your node. Well, that is what supercomputers were made for. So in a real supercomputer, you have the ability to do that. That is also why real supercomputers cost more.

I think it is an important distinction for that reason. While a supercomputer can do all a cluster can, the reverse is not true. Same with distributed computing vs a cloud. If you have something that takes basically no inter node communication, just occasional communication with a server, then you can distribute it all over the net, using low bandwidth links, unreliable nodes, and so on. A cluster can do that stuff too, but there are things a cluster can do that cannot.

Re:Ummm two things (1)

blair1q (305137) | about 3 years ago | (#37392666)

I think 2) is not seeing the whole story there.

They do have a continual use for mass quantities of computation. But it looks like it's not a 24/7 workload. And with $/core dropping like a rock, this iteration of the "biggest" may be cheaper than the last, and therefore not the sort of budgetary lightning rod that building-sized supercomputers used to be.

Re:Uh oh.. (1)

CUDA programmatically has far more limitations than MPI running on a cluster like this guy is describing... however, for things like gene sequencing, and various cancer research CUDA is the better choice. That is neither here nor their though. TACC uses CentOS on Ranger I believe... and they do lease cycles on it, and/or let people pay to run with batches. You could also contact xsede at TACC is part of XSEDE, but they operate somewhat autonomously and neither generally knows what the other is doing... TACC is also generally far more accommodating toward things like what you are asking...

We have this exact same setup (20% the size though) we use infiniband, we have not had good luck with 10Gige though we do use it for globus end points. 40Gig IB has better MPI performance and higher bandwidth at a lower cost. You can also get ethernet->IB gateways to help with any issues if you need to use IP over IB.
Also make sure your MPI library support OFED (open fabrics or you won't get the performance you want.

Anonymous Coward | about 3 years ago | (#37392166)

LFTR modelling? It's one of the main things holding back the tech.

Re:How about (1)

drwho (4190) | about 3 years ago | (#37392562)

OK, LFTR (Liquid Fluoride Thorium Reactor) development would be useful. Can you explain what modeling needs to be done? Is this merely a provisioning problem (you haven't got the computational resources), or it is also a programming problem, and perhaps even an algorithm problem (do you know what you want to compute)?

Another question is, who would own the results?

Yeah, I think we need more specific info here. I can't see any way a group would attract funding without spelling out all these items... however the submitter doesn't actually refer to funding, he states "I will be receiving everything necessary to build ...". What does that mean, exactly? Did he just buy hundreds of 386-based machines off the scrap heap? And, more importantly, does this person's supervisor know he apparently seems to think this is his own personal playground rather than a professionally run system?

Or maybe we have it all wrong. Reading between the lines, I immediately assumed he worked for an educational institution or a pharma company - but he doesn't say anything like that. For all we know this guy works for one of those rich pseudo-scientists... the kind of dabbler who has an "institute" with his own name in the title, and the mention of whose name makes real scientists roll their eyes. We just don't know enough.

Multiple super-computers instead of a single one? (1)

sisukapalli1 (471175) | about 3 years ago | (#37392228)

You need to specify additional information:

1) What about the data and storage? Many complex applications require vast amounts of data (e.g. climate change models, CFD models, GIS data sets that can complement or take advantage of modeling). Many end users may not be very adept at accessing these data.
2) What about the software? For example, CFD modeling software is very expensive. In some cases, open source software may not make the cut.
3) Does it have to be a single supercomputer? Why not split into multiple supercomputers and merge them as needed? That way, some groups have a more dedicated resource for themselves. The "biggest X ever" isn't as cool as it appears to be.
4) I presume the funds came in as a result of some proposal (using the word informally here, it could even be a one-pager that was sent to the university). The costs should be at least 5k per sever (based on what I've seen recently), so it's 6 million [I'd say 10 million even, unless my weak math is catching up with me]? So, that proposal would have some intended uses already.
5) Leasing it internally (to other groups in the university) may be reasonable -- it may even be a sweeter deal if you allocate a set of 10 or 20 servers for a group, instead of having it as part of a broader account access. You can tell them it is their "own machine".

I say this with no offense meant... I've noticed way too many people for whom the tool or technology seems to be the primary purpose (e.g. I do it using *EJB* or *distributed cluster* or *high availability database*). I spoke to someone that was working on app infrastructure for first responders, and was focusing on IDEs and integration, and his killer app was a download link to a weather channel app! When I mentioned that he needs some apps that really differentiate the system from others, his response was that we can run a contest for the apps. So, please avoid going that route -- in general, the tools are there to solve problems and not the other way round [with all caveats, sometimes the tools have to come first before we even realize what we had before that was very bad].

Well, congratulations on getting to play with 10M. I think I was rambling a bit, but the bottom line is: (a) don't make it one computer unless you can find a reason, and (b) approach different groups and offer the tool/service -- you need to do that till you get some traction.

Ethernet / Infiniband Tradeoff (1)

Rhalin (791665) | about 3 years ago | (#37392274)

Pros and Cons for each link, and it depends on -which- speed of infiniband / how they are bonded. Infiniband can get quite fast in the right configuration, if you want to spend the money on it, and even then, you could do similar setups with 10GB bonded ethernet, that might be cheaper.

One advantage I think ethernet has over infiniband (and correct me if I'm wrong here, someone) is that infiniband requires a specialized network protocol to use, where ethernet can use standard TCP/IP sockets. This is perfectly fine, since many cluster libraries can use infiniband...but using ethernet would open up your cluster to situations and use-cases where things like MPI may not be appropriate architectures - for instance, some types of cognitive modeling can benefit from the CPU resources available on the cluster, but their architectures don't always bind well to MPI metaphors (and for some programming languages / cognitive architectures, getting MPI to work is non-trivial in a cluster environment).

security (0)

Anonymous Coward | about 3 years ago | (#37392276)

Security with the GPU will be impossible.

They rarely have their own IOMMU due to the speed limit they put on DMA, and that opens up the system to major security disasters.

All of the systems I know of have no protection to prevent malicious/buggy GPU code from corrupting system memory and either taking over the node, or (better) just crashing the node.

And they are going to let you administer it? (0)

As a cluster admin myself.... infiniband!!! (2)

Fallen Kell (165468) | about 3 years ago | (#37392328)

I can not stress this enough. As good as 10gb ethernet is, the latency is still horrible compared to infiniband.

As for distributions, really, that depends on what you are doing and how your current applications are built/designed. Rocks cluster is fairly nice. Unfortunately we have not been able to deploy that due to our FOSS policies, which have really been hurting this project. So we have a mixed Red Hat and Solaris cluster using Grid Engine.

Anonymous Coward | about 3 years ago | (#37392338)

- Check if the Ultimate answer is really 42. Will take some time.

- Simulate the evolution of the US economy with and without stimulus. Ideal for Dem and Rep (depending of the result)

- Simulate the evolution of the US if the military budget were use for public health and education.

- Simulate some earthquakes and damages. (for insurance companies)

- Simulate a black hole. (for some astrophysics research)

- Simulate the chances of a non-educated young teen becoming a new rich rapper.

- Crunch numbers for SETI like projects.

- Look for patterns in NYSE.

- Estimate the public debt in 2020 if the politicians keep spending exponentially with some never ending wars in between.

- Calculate the mandelbrot set with super precision.

- Program a chess game.

Total BS (1)

friedmud (512466) | about 3 years ago | (#37392366)

I work with some of the largest supercomputers in the world... and I can tell you that this is BS. There is no way this guy got someone to give him enough cash to put this together without:

1. A Plan of what to buy / build
2. A sound reasoning behind what would be done with the machine.

Beyond that... that isn't even that large of a cluster. There are numerous computers on the east coast larger than that... at universities and government research labs (i.e. [] although maybe he doesn't consider Oak Ridge to be on the "East Coast").

Giving the benefit of doubt, I'm assuming that you mean that you have a purpose, but have spare processing power and would like to put it to use. In that case I would recommend maybe seeing if you could help out with Folding@home, SETI@home or CERN distributed computing.

rish87 (2460742) | about 3 years ago | (#37392580)

As somehow who works with supercomputers, I have serious suspicion about this . You do not get the funding for a supercomputer of this size without knowing these basic specifications. How can he be getting "everything necessary" in two weeks when he doesn't have a planned network, GPU's, OS or application? There is so much effort that goes into speccing these clusters, building them and then installing and configuring all of the administrative software such a queuing systems. Hell, if you're doing HPC work on supercomputers, you need an equally impressive storage solution to contain all of the data. It isn't a matter of sticking a sata hdd on each node and calling it a day.
