Parece ser que hay una nueva criptomoneda dando vueltas, o “minar” volvió a dar resultado, dado el bajo stock de placas de video (más que nada AMD) en el mercado.Para poder satisfacer la demanda y prevenir la escasez de placas de video hechas para “juegos”, ambas compañías están planeando anunciar ediciones especiales de sus populares placas gráficas diseñadas de manera específica para el minado.NVIDIA se prepara para lanzar la GeForce GTX 1060 con un GPU GP106-100, una edición especial para minado.Esta placa no tendría ningún tipo de conector y hasta no soportaría ningún tipo de juego.De acuerdo a varias fuentes, estas placas solo tendrían 90 días de garantía a diferencia de las ediciones clásicas, serían mucho más baratas que los mismos modelos para juegos, y se venderían solamente por partners autorizados (Asus, MSI, Gigabyte, etc.).Por el lado del equipo rojo, AMD también lanzaría modelos basados en Polaris para la minería, aunque los detalles todavía no se revelaron.

Además, quizá con la idea de ganarse un mercado que siempre fue dominado por AMD, Nvidia tambien prepara estaciones mineras en donde serán alojadas hasta 8 de estas ediciones especiales de GTX 1060 junto a un procesador Intel Celeron Mobile, 4GB DDR3, y almacenamiento en SSD de 64GB.Pueden ver el resto de las especificaciones y una foto de las placas en la imagen que dejamos a continuacion.Tecnologia Pubblicatio il 20 marzo 2013 | di bitquotidiano Guida facile Minare Bitcoin – Configurare il portafoglio e minare la moneta Installare il programma Bitcoin  scaricare la versione per il proprio sistema operativo (Linux, MacOs, Windows) e installarla come ogni altro programma.Minare la moneta Per minare la moneta occorre scaricare un altro programma “GuiMiner”./ /downloads/Kiv/poclbm/guiminer-20121203.exe Deepbit richiede di registrarsi sul sito https://deepbit.net/ Eligius è una mining pool che potete usare in alternativa, non richiede registrazione al sito, suhttp://eligius.st potete leggere le faq e la matematica che ci sta dietro, basti sapere adesso che Eligius, come altri gruppi, come Slush, usa sistemi sempre più diffusi, che in breve favoriscono quelli che lasciano il computer a minare tutto il giorno.

I tried setting all privileges in the folders in root - which are used for litecoin mining - to 777 and to change the owner to the usual user, but it didn't work.I copied the file /root/.cgminer/cgminer.conf to /home/user/.cgminer/cgminer.conf, set the user and the right to this file, but this didn't solve the problem too.But why can only root access the OpenCL functions which are used, why can not the normal user do so?bitcoin icevaultlitecoin miner-configuration up vote 0 down vote You should be able to add your current user to the plugdev group in Linux to be able to access the GPU as a standard user.chat bitcoin italiaThis can be accomplished by the following command: sudo usermod -G plugdev -a whoami There may be some additional bits of information that are relevant in the README on the cgminer website.ethereal for linux

up vote down vote I'm not familiar with cgminer -- i hope to learn more about it this year -- but a wild guess would be that it tries to configure some device driver, and that needs root priviledges.If you are worried about using the root user for mining, maybe you can add this device driver priviledge to a common user using sudo.bitcoin to sterling conversionup vote down vote Again, I am not familiar with cgminer but when I attempted to use it, I ran it with sudo cgminer --verbose -T This should work.ubuntu live bitcoinBrowse other questions tagged litecoin miner-configuration or ask your own question.free bitcoin qr codeFor the past year, enthusiasts have been chomping at the bit waiting for the next generation of graphics cards to arrive.bitcoin card vector

The 28nm node has persisted for far longer than any previous generation, and while both AMD and Nvidia have introduced multiple products on that node, customers have clearly wanted the power efficiency and performance improvements that the 14/16nm node could provide.Today, Nvidia showcased the full HPC version of Pascal and detailed what the card would offer compared with its previous Maxwell and Kepler products.When Nvidia designed Maxwell, it made the design to remove much of the double-precision floating point capabilities that were baked into its previous Kepler architecture.The old Tesla K40, based on the GK110 GPU, was capable of up to 1.68 TFLOPS/s, while the Tesla M40, which used the Maxwell GM200, could only reach 213 GFLOPs.The M40 still had an advantage over the K40 in single-precision floating point, but double-precision floating point performance was sharply curtailed.As we discussed last week, when AMD launched its FirePro S9300 x2, this limited the kinds of workloads where the M40 could excel.

Pascal’s current GP100 variant adds back all the double-precision floating point that Maxwell was missing — then stuffs some more in, just for good measure.The chart below compares Kepler, Maxwell, and Pascal.Note that the dev blog post states that Pascal can include up to 60 SMs, while the variant described below has just 56.One interesting aspect of Pascal’s design is that Nvidia has again reduced the number of streaming cores in each processing block, or SM and adopted the same ratio that AMD uses, with each compute block containing 64 processors.The total number of streaming processors has increased 17%, as has the number of texture processors.There’s no word yet on ROP counts, but assuming Nvidia followed its historic pattern, the GP100 should have at least 96 ROPS and possibly 128.Base clock is also up 40% over Maxwell, and while Tesla clocks are typically more conservative than their desktop counterparts, the fact that Nvidia squeezed a 40% clock jump out of this silicon suggests we can look forward to similar gains when Pascal comes to the consumer market.The memory interface is the largest generational upgrade.

HBM2 offers a 4096-bit bus and 720 GB/s of memory bandwidth, compared with 336GB/s of bandwidth available on the highest-end Titan X.Pascal also utilizes a simpler datapath organization, superior scheduling with better power efficiency, overlapped load/store instructions, support for Nvidia’s NVLink interface, support for 16-bit floating point (half precision), and improved atomic functions.GP100 also supports ECC memory natively, meaning there’s no performance or storage penalty for activating the feature.One note on NVLink: There’s been confusion over where and how this bus is used.For the most part, NVLink is a method of connecting multiple GPUs to each other, especially cross-connections in a multi-socket system, where forcing GPUs attached to two different CPUs to talk to each other would significantly degrade performance.NVLink can be used to connect the GPU to the CPU directly, but Nvidia’s blog post specifies that this is only applicable to POWER processors.The diagram above is described as follows: “The [above] figure highlights an example of a four-GPU system with dual NVLink-capable CPUs connected with NVLink.

In this configuration, each GPU has 120 combined GB/s bidirectional bandwidth to the other 3 GPUs in the system, and 40 GB/s bidirectional bandwidth to a CPU.”Nvidia is also claiming that Pascal will offer “Compute Preemption” with a significantly improved computing model.This is one area where Team Green has notably lagged AMD, whose asynchronous compute performance has been much stronger than anything NV has brought to bear.Asynchronous compute and compute pre-emption are not the same thing — we’ll have to wait for shipping hardware to see how this compares with AMD’s implementation and what the differences are.It’s obvious that Pascal will significantly improve Nvidia’s HPC position, and that’s important since the company has huge plans for deep learning, self-driving cars, and other HPC workloads.Pascal looks like it’ll be a potent match for Xeon Phi, Nvidia’s primary competitor in this space.Nvidia has remained mum on consumer launch dates, however, so we’ll have to wait and see when this tech makes it to the mass market.
