The following vendors are for the post part not really "endorsed", and in no case am I responsible if you use one of them and have a poor experience.
Some of these vendors I do have direct experience with. Others have just contacted me and asked to be added to the list, and I've done so (without even charging them, which is probably slightly insane on my part). Still others have contacted me with rich bribe offers such as tee-shirts, penguins, and coffee mugs or tiny screwdrivers, causing me to fill them in below with a smile.
Clearly I'm a bit of a slut, but I've still got my pride and standards. Truthfully, I'll list almost anyone if they're really and truly quasi-dedicated linux/beowulfish vendors, but (for all of you who read this)...
...USE THEM AT YOUR OWN RISK. I make no warranty whatsoever about any given vendor being suitable, cheap, or reliable even if I've used them before. I could be mistaken, after all, or I could be lying. The latter isn't horribly unreasonable, if the vendor has bribed me heavily with tee shirts, coffee mugs, free palm pilots, or (always useful) money to tell you how great they are. So you shouldn't fully trust even an open endorsement. Who knows how many stuffed penguins stand behind it?
One last remark. If you have used a vendor on this list or do use a vendor on this list and have a bad experience, feel free to let me know and I may add a reference to that to their listing or even remove their listing altogether.
I like these guys and do business with them pretty regularly. They are the sole supplier for the systems in my home beowulf because they are quite cheap and literally two miles away from my house. This allows me to get service "instantly". For example (true story), 12/4/00 I was rebuilding my home beowulf (putting it on a nifty heavy duty steel and particle board shelf unit, actually, to which I had attached rolling casters -- very cool and cheap!) and naturally my primary server/desktop (a dual Celeron on the Abit BP6) refused to come back up -- no power at all. I suspected a blown power supply, but didn't want to mess with the swap game at home.
So, I simply picked up the unit and carried it to the car, and trundled off to their South Square store. I plopped it down on the counter and said "I think the power supply is blown". Twenty five minutes later I was out with a new power supply installed at no charge and no questions asked, as the system was still less than a year old (by around three weeks:-). Of course I also grabbed some newly cheap SDRAM and even popped for a 30 GB disk for all my MP3's while I was there...
This kind of service is why I buy from local vendors if/when I can find a decent one. Intrex is exceptional even in this regard -- their systems come with a lifetime labor warranty, and that's the expensive part of buying ANY system -- hardware (replacement or otherwise) is cheap, but the time required to swap power supplies, motherboards, and so forth around to identify and replace a bad part is very, very expensive. To me -- it is my time. I'll therefore make an exception for Intrex and "endorse" them even though they don't give me coffee mugs or mouse pads for free. Their prices are low enough I can afford to buy my own with what I save.
Oh, and maybe I can get a cool T-shirt out of them for the link. Take it for what it is worth...
Blade solutions generally permit one to achieve the highest possible CPU densities. Transmeta clusters can run cool, although it is cool and relatively slow. However, they are expensive, and hence most likely will be of interest to people with a highly nonlinear cost profile in their physical infrastructure -- extensive renovation required to house, power, cool a more traditional cluster with (otherwise) better cost benefit. Still, worth looking over, and prices can always change.
These guys get some extra kudos from me as they've been extra nice to me over several years. No tee shirt(s), but they've given me the chance to work with certain bleeding edge hardware for free before it even "existed". Very nice folks, good quality hardware.

Through innovative hardware, complete cluster management software, service and support, Linux NetworX provides end-to-end clustering solutions. To date, the company has built some of the largest cluster systems in the world and has developed unique hardware and versatile software to facilitate overall system management. Linux NetworX has offices in Utah, New York, Calif. and Texas and worldwide distributors."
"About ClusterWorX: ClusterWorX allows users of Linux NetworX clusters to control the cluster as a single system, and provides remote monitoring and management capabilities. ClusterWorX can be accessed through an easy-to-use graphical user interface (GUI), command line and HTML. Other management tools include remote access, disk cloning and serial access to nodes, including remote monitoring and resetting of individual nodes without effecting the uptime of the entire system. Disk cloning is a valuable feature for large cluster systems because it allows software and other updates to be installed on one node and automatically distributed to the entire system. All features are architecture independent."
"Connectivity is provided using ethernet, Myrinet or Dolphin interconnect technology. The company was formed in 1982 by Stephen Fried, physicist and coinventor of the HF chemical laser (Star Wars). Microway has provided state of the art products for high speed numeric processing to the university and government marketplaces for over 18 years. Microway is API's largest US customer for UP2000 and 21264DP Alpha motherboards and processors. The company designs proprietary rack chassis for maximum nodes per cubic foot, and has a fine reputation for delivering fully configured clusters that work! Microway has configured Linux based systems since the early days of the Red Hat releases. Today we specialize in large Beowulf clusters for customers with HTPC applications from chemical engineering, mechanical engineering, CFD, molecular modelling, simulations, biogenetic research to designing America's cup racing keels, and jet engines. Our customers also include ISPs and other ecommerce companies."
For what it is worth, I do remember Microway from years of reading PC Magazine and drooling over their co-processor (i810 and other) boards and fancy matching compilers. Although I have no clue as to where they stand in the grand scheme of cost-beneficial turnkey beowulf systems (so you'll have to visit their website and talk to them and find out for yourself, which you'd do anyway with ALL of these vendors if you had any sense) I will say that in one sense, they were a direct philosophical predecessor of beowulfery. They made an attempt to achieve the same goal of providing commodity supercomputing at an affordable price in a readily available platform. Of course, they tried to achieve it by putting 2-4 very high end processors on a single ISA bus card with very much custom and proprietary high end compilers and a unique architecture, but there is nothing wrong with that, especially in the context in which they were working. For a long time, they probably led the world in cost/benefit measured in minimum commercial cost/FLOP in a single platform. And they are sending me a T shirt, so they must be decent folks.
NAG is a software company that specializes in reusable mathematical and statistical software components. We have been in business for 30 years and have been involved in many projects with the Department of Energy, Department of Defense as well as being able to help many NPACI and Alliance partners. (There are about 40 site licenses within the NPACI and Alliance members which makes collaboration and sharing of software containing NAG very easy.) NAG recently released a new version of the NAG Parallel Library that utilizes MPI for Beowulf computers. The product works with either PGI's compiler or the Gnu product.
All of NAG's products are available for "test drives". NAG will also be coming out with a version of our SMP Library for Intel/Linux next year.Best regards, Tony Nilles

"Many will say that `memory is memory'. While that used to be the case, memory today is anything but standard. With the onslaught of new technologies, it has been a challenge for integrators and OEMs to maintain true compatibility. To that end, Ventura Technology Group (VTG) is a tremendous resource, since we design and manufacture the highest quality server class memory. While our products are compatible among a wide range of platforms (SUN, IBM, HP, APPLE, COMPAQ, DELL, HP, IBM, INTEL, TYAN), our focus will always be on higher density modules (128MB, 256MB, 512MB, 1GB). Rounding out vital service offerings, VTG stretches ahead of the competition in the following areas:
Every module design is manufactured to exceed OEM specifications
* Certifications with major OEM's (Tyan, Intel, Supermicro) insures constant compatibility
* All memory technologies are manufactured in our own ISO9001 certified facility
* All memory modules are manufactured using top grade DRAM and SDRAM (Samsung, Micron, NEC, etc...)
* International and Domestic supplier relationships insure competitive pricing and consistent supply
* Lifetime warranty with the benefit of cross shipment where needed
Along with all of the above benefits, VTG continually provides competitive prices."
Powercockpit can deploy and update complete OS and solution stack(apps) to bare metal servers on a complete blank hard drive from a custom repository of saved images to multiple hardware configurations instantly using multicasting. Also, re-purpose servers on the fly throughout your local and remote clusters. Don't waste time on tedious cluster management. Powercockpit is more user friendly and robust than using Kickstart or System Imager. Although they are useful solutions they lack: GUI, cluster mgmt support, no rpm control, no cluster status ability, no multicasting and require tedious hands-on support and effort.
The primary strength of this tool appears to be how it encapsulates a lot of expertise and hides in behind a GUI. As was the case with Aduva's product, I suspect that this product will find a warm reception in a relatively undermanaged corporate environment, but that most University and Government shops will prefer to work with lower level, fully open source tools and "roll their own" cluster, so to speak. Still, worth looking over. They offer a free 30 day demo at the link above, so it is easy to try it out.
Truthfully, this looks like a good place to bookmark for its possible applications in e.g. physics labs as well as in HPC cluster rooms. They have linux-read open C source drivers for reading the devices, and apparently porting their output into various forms is pretty straightforward. Prices (when I looked -- you should obviously check again) seemed to be less than $200 to equip a three-sensor plug that should be able to monitor an entire server room -- chilled air temp at the output ducts, heated air temp at the return duct, ambient air out where the air is mixed. Alternative configurations add humidity sensor information or monitor e.g. door openings and closings with a standard door sensor.
One of these, a TV card, and an X10, and for less than $300 you have the equivalent of a far more costly Netbotz appliance, presuming that you have a node or system in your server room with a bus slot and a tiny bit of attention to spare polling the device(s).
Vendors! Your product could appear in this list if you meet my demanding criteria! To wit:
|1.||The request must be accompanied by unmarked
bills in a brown paper envelope, or tee shirts, toys, or other
good geek gelt as a bribe.
|2.||It must be directly and clearly linux based and linux supported. WinXX-associated vendors need not even ask, unless they also have a linux product. I don' be doin' Windows...|
|3.||It needs to have something to do with beowulfery or high performance cluster computing, as this is a beowulf site. Turnkey beowulf vendors, support/service vendors, distribution vendors, hardware vendors, network vendors, all are welcome.|
|4.||OK, I was kidding. You don't really have to give me anything to get it listed, especially if I find your product intriguing or think that having it represented here might be beneficial to somebody trying to engineer a beowulf solution. On the other hand, modest bribes certainly help to motivate me take my time to make the entry, and if you want a "real" endorsement I really do have to have used the product one way or the other.|
Feel free to send requests for inclusion to my email address below and to send non-monetary bribes to Robert G. Brown at 3209 Annandale Road, Durham NC 27705, USA. Monetary bribes will have to wait until I get my bank account in the Caymans opened...;-)
