Nvidia Unveils First Mobile Supercomputer for Embedded Systems
- kailuowang 13y agoI am surprised that no hackernews users has responded to this news yet. It sounds an exciting platform for all kinds of innovations.
- jensnockert 13y agoThe people who were interested probably bought the AMD-powered Gizmo Sphere already? (www.gizmosphere.org)
- maximux 13y agoCould something like this work for a home server?
- amckenna 13y agoYou may be able to use it for a home server but unless you have a particular need for the NVIDIA parallel processor you're better off with other cheaper systems. If you're looking for a tiny home server check out a Raspberry Pi or ODroid: http://hardkernel.com/main/products/prdt_info.php http://hardkernel.com/main/products/prdt_info.php
- sp332 13y agoYou can get the same performance for less money with a normal graphics card. Assuming you need a workstation card (for support or something), http://www.newegg.com/Product/Product.aspx?Item=N82E16814133482 http://www.newegg.com/Product/Product.aspx?Item=N82E16814133... the Quadro K600 also has 192 cores and similar ~330 GFLOPS performance. It will probably use more power, but it's about the same price. If you use gaming cards instead of workstation cards, it gets much cheaper.
- pantalaimon 13y agoWhy would you need a powerful GPU in a home server?
- skrowl 13y agoI've been looking for something to replace my Ouya as an XBMC box, but with enough power to support the incoming 4K content. I'm not sure this does it.
- dublinben 13y agoYou'd probably be better off waiting for a 4K codec to settle out, and for hardware decoding support in new chipsets. As it stands, HDMI is barely capable of pushing 4K to the handful of displays that will accept it.
- rch 13y agoI'm impressed by the price point ($192) and pretty curious to see what I can do with it besides computer vision. Bioinformatics co-processor that works with my laptop? I've wanted that for a long while now.

- pfraze 13y agoAnybody know if the FPGA's branching model has been improved?
- profquail 13y agoWhat FPGA? Do you mean GPU? If so, then - it's improved a bit over the years, but it's still much different than CPU programming, and branching remains relatively expensive.
- pfraze 13y agoI have my terms mixed up. I thought GPUs used FPGAs, but I was wrong. Thanks for clearing that up.
- ramseyymcgrathh 13y agoCould be a great platform for WPA2 key cracking and encryption bruteforcing when paired with tools like Pyrit or HashCat
- boredinballard 13y agoI wonder how many pmks it could get through per second in Pyrit. I imagine it's a bit more power efficient than a bunch of GPUs going through pmks.
- maga 13y agoHere's more technical specification: http://goo.gl/AigVq5 http://goo.gl/AigVq5 Though I can't find its power consumption info anywhere. If anyone happens to stumble upon it, please let me know.
- markhahn 13y ago192 kepler cores: don't bother. this is just a desperate attempt to get someone to take TK1 chips off their hands. coincidentally, I'm sure, but AMD is shipping their AM1 platform.
- hershel 13y agoThis looks pretty similar to the parallela, with better price, nicer software support and better manufacturing horizon. Oh well, that was somewhat predictable: parallela competed with nvidia in something that nvidia cared about and could execute.
- trhway 13y agono, they are very different. NVIDIA is SIMD, a 32 thread warp doing the same instruction in lockstep (in 4 cycles usually on 8 SPs, the 192 SP chip can run 24 warps simultaneously, though specific numbers may change a bit from version to version) and heavily penalized for in-warp divergence. Parallela - i.e. Adapteva (http://www.adapteva.com/epiphanyiv/ http://www.adapteva.com/epiphanyiv/) is 64 independent (execution-wise) RISC cores.
- zemo 13y agothis is very cool. It operates in the "sub-10 watt space", had pretty decent io options for a device of that size, no apparent moving parts, decent graphics capabilities, and a reasonable price point. Seems like a great little device for a media machine or a graphics installation; somewhere between a raspberry pi and a mac mini.
- dman 13y agoI hope Nvidia throws more support behind this than they did with past Tegra developer kits. I bought a Tegra devkit and perpetually got the feeling that the driver support / dev relations was being done by one person in their spare time.
- fidotron 13y agoI wonder if something like this could be the start of a decent key-value appliance. Hardware designed to perform the role of memcached on the network or similar.
- noahl 13y agoHmm. At first I thought this would be a waste, because you couldn't use all of its fast compute capabilities on doing key-value lookups. But these things also have much, much more memory bandwidth than regular CPUs (I can't remember if it's 10x or 100x, but that ballpark), and that might work well for these applications. But I don't know how the GPU's memory caching infrastructure works. If the bandwidth is only for serial reads, that could be a problem.
- wmf 13y agoK1 has about the same memory bandwidth as every other mobile SoC, which is to say not all that much. Don't compare it to discrete GPUs.
- fidotron 13y agoTrue, but in my experience if you can avoid hitting the memory the amount of computation you can do per thing is absolutely terrifying. The main thing I had in mind here was hashing for bloom filters. i.e. do the different algos in parallel on a GPU, then pass those values for the main lookup to be done by the CPU.
- jjoonathan 13y agoLike Content-addressable memory (CAM)? I've heard routers have used the stuff to do fast table lookups since forever, but I don't know if anyone has tried implementing a data cache with it. http://en.wikipedia.org/wiki/Content-addressable_memory http://en.wikipedia.org/wiki/Content-addressable_memory
- MertsA 13y agoIf you wanted raw memcached performance there was an awesome paper on using an FPGA tied to 24GBs of regular DDR3 RAM and a 10G ethernet port. The result was a memcached server with 3.5 to 4.5 microsecond response time, capable of saturating the 10G port even with tiny key-value pairs, and 13 million requests per second while using 50W of power to do so. http://0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f.r43.cf2.rackcdn.com/11566-hotcloud13-blott.pdf http://0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f...
- sharpneli 13y agoIf they would only stop hating OpenCL (read: Actually support it) I'd purchase one in a heartbeat as a testing rig and experimentation rig. Having a board which works only with a certain vendor specific API is not really that useful unless I'd specifically want to develop a full fledged product using exactly that particular board.
- madeye 13y agoThis SDK will have fully support of OpenCL 2.0
- thomasjames 13y agoDo you have a link for that? I would be super excited to see them get back on top of their OpenCL support. They have been a 1.1 for a long while now.
- jxjdjr 13y agoSo many posters here do not have a clue. Can I use it as a media server? So its similar to parellela! Xyz is better, cheaper, faster... People - This is the beginning of an epic shift in focus. We are at beginning of an exciting new period for computing. The focus is shifting to function - out there in the real world. The goal behind this nvidia drive is no less than the creation of useful real world robotics. This marks the very beginning of a curve that will take us all the way to west world. As long as the semiconductor industry keeps cranking out the production nodes, this story will remove humanity from the process of production -forever. You are here at the beginning, you are here to bear witness, don't let the gravity of this moment escape you.
- zackmorris 13y agoI totally agree. This is so long overdue! My only gripe is that I decided to look at OpenCL and CUDA today and felt kind of.. underwhelmed. I have a lot of OpenGL experience and I guess it's not surprising that they are so similar to framebuffers and shaders. But I was really hoping for true general purpose computing, more like a hybrid between VHDL and say MATLAB. Ideally it would work like Go, where you would send a C-style function off to an execution unit or refer to other units by id, and use something like fork/join to tabulate the results, and maybe just give up on the notion of a global memory space. Instead it looked more like image processing kernels for doing convolutions and stuff, and I mean that's great, but didn't exactly wow me. Maybe I'm missing something fundamental? Does anyone know of a site with more of a computer science approach, say like http://golang.org http://golang.org, instead of so much emphasis on graphics? Or possibly a compiler that would convert Go/MATLAB/Python to OpenCL/CUDA? Am I alone in feeling a little mystified here?
- robomartin 13y agoIs this for processing USB webcam data? I'd like to use industrial or broadcast-level cameras but the board seems to be lacking support for these kinds of inputs. Also, in both of those domains cameras can deliver true 10 to 12 bits per color channel uncompressed performance. Webcams don't come close, as far as I know. Am I wrong?
- wmf 13y agoTegra 4 has a MIPI-CSI interface for image sensors and I would assume K1 is similar. Supposedly you can combine the ISP and GPU for image/video processing.
- rhoads 13y agoWhat about using this for bit/alt coin mining? Do you guys think it is a good ratio of performance / power consumption?
- jmpe 13y agoNotice they use the GigaFLOPs metric, which is a (maximum) floating point measure. Bitcoin hashing (it's been a while for me) is compute intensive on integer math. For a good ratio of performance/power you'd want to look at architectures like the GreenArray devices. But the world of bitcoin hashing is now firmly positioned in ASICs. You can't cut architecture fat beyond that so you'd have to look at (general purpose) architectures built on a faster silicon technology. Wouldn't count on it. http://www.greenarraychips.com http://www.greenarraychips.com
- wmf 13y agoKepler is fairly useless for mining.
