  1. A good progression on Open-Source GPU Used For Research (binghamton.edu) · · Score: 1

    I remember a few year back i was a member of the OGP group.

    The group was able to do a development platform for the hardware. Also a demo code was made to support VGA and a first iteration of a fix GPU was made.

    At the end we were a few working on a spec for the Programmable GPU, before starting to code it to test.

    What was released was another project in collaboration with the leader of the OGP. For those who don't get what the news mean :

    -It's a programmable GPU
    -It can be turned into hardware
    -People can thinker with it and improve it
    -It's a working base for hardware test in FPGA and software simulation
    -The available and open code for a GPU.
    -It's not commercial, it's academic
    -Graduate and undergraduate student across the globe now have access to it for student project and thesis work

    What it's not is:
    -A graphic card you can buy

    It is a pretty great news for those into the open hardware community. Albeit a latter one than most wished. But it is a game changing moment.

  3. From windows 7 to xp on Time To Dump XP? · · Score: 1

    Where I work we are doing embedded system development. When we started we were given nice laptop with windows 7.

    After a few month we start to see the limitation. Most software run in windows 7 or linux no problem. But most development kit only have windows XP driver.

    So because of the driver issue we are forced to go back to Windows XP and be limited with the ram we can use on our computer.

    After using W7 for quite some time I must say it work well enough I don't like everything but I prefer linux with kde. But at least Windows7 did support well multicore setup and more than 3G of ram.

    Yes you are spending too much with over the top feminist. Both gender can be stupid and petty it's not the sole province of men or women.

    For the women to try to trap a guy by getting pregnant, I believe it happen fairly often. Why? Because even if the guy quit she can ask and get from the justice system quite a bundle of money from him, because she's having 'his' kid.

    For the opposite, the man trying to trap a woman by having his kid, it could also happen. But there's way to prevent that from happening. If she don't want it to happen, she can prevent it. If she can't stop him it's called rape. And there law for that. After the fact there also a few options : morning after pill, abortion and adoption.

    Megahertz Myth. As far as I can tell, over the last 5 years individual cores have still been getting faster, just not with higher clock speeds.

    They are going faster by shortening the pipeline so you get a shorter execution time if you have branch. Also there are more execution unit. At first there was only 1 alu doing everything. Now in a standard cpu you find multiple dedicated unit for integer, logical and float operation. It allow to execute many operation in parallel, as long as there's no dependency between the data.

  8. Cool battery on High-Temp Superconductors To Connect Power Grids · · Score: 1

    What's nice with a system like that is if they make truly connect each section together you get a inductance that carry 15 GW(3*5GW per section). That's useful for load balancing but you can also store that energy in the system.

    Since it's a superconductor you get one freaking huge battery. It's not a lot to run en entire state but it should give a few moment in case of power failure.

  9. Re:Burnt out on How Does Flash Media Fail? · · Score: 1

    The operation theory for flash is based on that effect. In the insulator layer there is a floating gate who will get charged to make the memory effect. This charging and discharging of the floating gate is made with a higher voltage than the reading voltage. During the write/erase operation the insulating layer get damaged. That's why you have a maximum number of write cycle.

    Sorry but you are wrong. What people from Quebec want is being able to live and experience their culture. Every culture vector is the corresponding language. Most Quebecer consider that other culture bring something new to their culture. Montreal is one of the biggest culture melting pot in North America.

    It may seem that Quebec people are closed on themselves if you read only the laws, but some of those rule are there to force lazy company. Also those laws where passed in reaction to the English-Canadian action in the past to try to destroy the French-Canadian culture.

  11. Neutron source on Fusion-Fission System Burns Hot Radioactive Waste · · Score: 1

    There is a high quality neutron source existing. The fusion reactor that was push by Dr. Bussard a few year ago. For those that don't remember it was a reactor called a polywell.

    Dr.Bussard was believing that it could break even and the remaining question was one of scaling and engineering not physics.

    Depending on the fuel and the scaling you could have your combined fusion-fission reactor probably under a decade if you want to burn fission material. For net power the time frame was somewhat similar for commercial power plant that wouldn't produce neutron.

    There was news of a review of a new set of experiment and the result where interesting enough that the navy is still interested in funding it.

  13. Re:About overclockers: on Overclocked Memory Breaks Core i7 CPUs · · Score: 3, Informative

    Probably because the IO voltage rating of the Intel technology for the transistor is lower than AMD. Intel CPU is on a 45nm process and AMD a 65nm process, usually bigger process are more tolerant. If Intel IO run at 1.5V we can suppose there are 2 reason for the limit of the ram.

    First if the IO go beyond the 1.5V you can either break the protection diode on the cpu pin or inject current on the power line for the IO on the chip. That part is bad because it force the power supply to compensate for that and try to keep the same voltage on the power pin. While you have higher voltage incoming from the digital pins creating a differential on the internal power supply line, who start to carry more current than designed. That cause the line to heat and dissipate a lot of power eventually breaking them.

    Second option is that having a higher voltage the transistor aren't made to support, is going to cause more electron leaking trough the gate and eventually breaking the isolation layer. If the isolator become to cracked by the electron a pinhole could form creating a contact between the gate and the substrate. Transistor gate are in reality small capacitor so contact between the 2 side it become a wire. That would cause the transistor to stop working. It also would inject changing voltage on the power line inside of the chip. Worse than the previous problem because now if a pinhole is created you can inject either a positive voltage or ground level on both power line and at different rate everywhere. That would effectively assure the destruction of the IO bank.

  14. Re:Or until we invent... on Breakthrough In Use of Graphene For Ultracapacitors · · Score: 1

    What is of interest with the ultra capacitor, when they get their voltage rating up, is going for short term charge. Battery are more strained rapid charge and discharge than would be an ultracapacitor. The best thing would be to have both.

    The capacitor could charge from the battery slowly and not strain it and then discharge fast for the initial current requirement for starting the motor. The capacitor could also be used to hold the charge for when the car brake and the motor become generator after use the energy recuperated for the next start. Also when the car get parked to hold the charge and feed it back slowly in the battery, unless the capacitor leakage current is minimal in that case keeping the charge in the capacitor is interesting.

  15. Re:I think not on Open Source Graphics Card Available For Advance Orders · · Score: 3, Informative

    The FPGA performance with the basic GPU would be enough to have a glitch free experience when using a 3Ddesktop in linux using the card acceleration or playing some old game. The thing is,the FPGA is probably going to run near 100MHz with 1 or 2 fixed pipeline so the performance will be ok for a desktop and stuff. For the latest game the framerate isn't going to be acceptable.

    Once the design is finalized it's going to be ported as a chip. The initial production cost for fabbing a chip is near 1 or 2 million for about 100k unit. Once the chip is fabbed the unit cost drop dramatically. Using that final chip you can save a lot because you need a simpler board and less component than the development board.

    Also once fabbed the chip is going to have more pixel pipeline and will be running a lot faster.Why more pixel pipeline and faster? A fabbed chip is more efficient than a FPGA both in term of surface usage and performance because of the way the circuit is made. So it allow the developer to use a maximum of surface. Since rendering graphics is a highly parallel task the graphics pipeline is easy to duplicate. Also usually in most design today the chip size is more dictated by the IO density than the core so there always space to add more pipeline.

  16. Re:There is no such thing as an all-purpose CPU on IBM Ships Fastest CPU on Earth · · Score: 1

    Most program are hard to write in parallel because the language is not made to write parallel code. Some language that are used to write hardware like VHDL and Verilog are quite easy and are defined to produce parallel code. Those language are made to be fully parallel, in them writing some sequential code is harder.

    So If you want to make programming multiple thread easy you need new language that support it directly and not by doing some strange stuff to make it possible. Maybe something like C/C++ but who support out of the box something like token to pass between function. When a chunk of code is finished the token is send and the programmer wouldn't need to bother with it since it would be compiler side. The only trouble would be at compile time there would be a need to create a dependency graph to cover the whole dependency graph for each function and see which one can work at the same time without trouble.

    What I don't like in those article is, they don't consider that in Islamic country the best regarded profession are engineering and medicine. If you look at people going to a university most people would be in those 2 domain. Since those 2 profession are well considered you get the most brightest person there. Sometime they are indoctrinated before entering or meet people who make them change their view, even if somebody is smart doesn't mean he can't be stupid.

    So yes it's possible that the people at the top of terrorist group are engineer they are usually smart enough to not explode them self and smart enough to make plan and make them work. I suppose if your a terrorist boss you want people who are able to make damage acting for you and the longest possible time. And that would probably be engineer.

  18. Re:Sorry to be a spoil-sport, but on Researchers Achieve Amazing Memory Density · · Score: 3, Informative

    Actually the technology they present is quite realistic. I did look at the article and the technical paper available on their website. They are talking about building the conducting bridge in an heavily doped material where the conductible material are sphere of approximately 20nm with a spacing of approximately 2nm(approximately 2 atoms diameter).Submitting such a solution even if it a "solid material" to a differential potential will create a field who could cause something like electro migration. Depending of the field applied the particle in the matrix will stretch or contract the conductible material and create/destroy bridge. A movement of a few atom at that scale doesn't require a lot of power and in a matrix atom without a solid crystalline structure it would be made rather easy by the available hole in the structure.

    For the number of cycling the material can do, they rate a rather big number of cycle. For that part I still held my doubt but for the rest they seem ok.

    The way spore is coded with procedural-oriented behavior. It would really simplify the process to also code the physic component of the game for a ppu card.Since it's an open ended game anything can happen. So your best bet is to code a physic engine as open as you can, to cover a maximum of possibility. Since you cannot prerender anything or have an artist define everything.Also it would allow realistic movement for you creature and their interaction with the environnement. From the fluid dynamic when you are a bacteria to planet movement when you are a spacefaring race.

    It wouldn't surprise me if that's one of the first game to use an ageeia ppu card.
