Essendo un Intel è già abbastanza messo bene cmq, con i VIA è era necessario un aggiornamento del BIOS per la serie 4xxx e forse pure per la 3xxx (non ricordo bene ora il problema mi si pose con una 4Core Dual SATA2 di ASRock con chipset VIA).

CUDA 3.2 RC2: CUDA Toolkit 3.2 RC (September 2010) Nsight 1.5 RC: NVIDIA Developer Tools Support Center

Per potere puoi, ma come ho detto l'ultimo BIOS è del 2006 (e la scheda del 2004 col primo chipset in assoluto che supportò il PCI-EX) e la scheda del 2010, ovvero non vorrei ci fossero rogne.

Alimentatore a parte sei limitatissimo da quella piattaforma. Domandati se ha senso spendere dei soldi in una VGA e non nel resto del sistema piuttosto Essendo basata sul vecchissimo (ormai) i915 (anno 2004) non vorrei ci fossero cmq problemi di "dialogo" con un scheda nuova come la 5xx0: il bios ad esempio è sicuramente da aggiornare ma non so se basta. http://www.asus.com/product.aspx?P_ID=gxw6071g5eeMSAwX L'ultimo BIOS è del 2006. IO - io - non mischierei mai cose così diverse come età di produzione.

Aggiungo la notizia di oggi (che è presente anche nelle news del sito): RICORDANDO CHE LA ST E' ITALIANA Nvidia and Portland Group Announce CUDA C x86 Compiler - X-bit labs The Portland Group, a wholly-owned subsidiary of STMicroelectronics and a leading independent supplier of compilers for high-performance computing, on Tuesday announced it is developing a CUDA C compiler targeting systems based on the industry-standard general-purpose 64- and 32-bit x86 architectures. The PGI CUDA C compiler for x86 platforms will allow developers using CUDA to compile and optimize CUDA applications to run on x86-based workstations, servers and clusters with or without an Nvidia GPU accelerator. When run on x86-based systems without a GPU, PGI CUDA C applications will use multiple cores and the streaming SIMD (single instruction multiple data) capabilities of Intel and AMD CPUs for parallel execution. "CUDA C for x86 is a perfect complement to CUDA Fortran and PGI’s optimizing parallel Fortran and C compilers for multi-core x86. It is another important element in our on-going strategy of providing HPC programmers with development tools that give PGI users a full range of options for optimizing compute-intensive applications, while allowing them to leverage the latest technical innovations from AMD, Intel and Nvidia," said Douglas Miles, the director of the Portland Group. The announcement by Portland and Nvidia appears to be pretty important for the whole industry in general and the graphics chip designer in particular. On the one hand, it will be possible to recompile almost every software designed for Nvidia CUDA-compliant hardware to run at x86 architectures. On the other hand, it will be possible to easily port a multi-threaded x86 program onto CUDA-compliant platform. As a result, it will be easier for developers to realize benefits of Nvidia's multi-threaded architecture. In addition, with the new compiler it should be easier for software developers to write applications that use both CPUs and GPUs. "With the CUDA for x86 CPU compiler, PGI is responding to the need of developers who want to use a single parallel programming model to target many core GPUs and multi-core CPUs," said Sanford Russell, general manager of GPU Computing software at Nvidia. A big question is how well it is possible to recompile an originally x86 applications for CUDA architecture and vice versa. Intel is currently working on its MIC architecture that will result into explicitly multi-core x86 chips, which can potentially compete against Nvidia's graphics chips with hundreds of stream processors. The new PGI CUDA C compiler for x86 platforms will be demonstrated at the SC10 Supercomputing conference taking place in New Orleans, LA, November 13-15, 2010. Già ora cmq è possibile usare come "target" nella compilazione la CPU, ma probabilmente i nuovi compilatori del PGI permettono una maggiore efficienza!

Pure io, ma il trend ahimè è quello.....e le aziende che producono le GPU non sono certo fondazioni umanitarie :p La cosa a me dispiace 2 volte poi, dato la sopraffina arte ingegneristica che c'è nella creazione di quei "mostri" che sono le GPU attuali, dalla fase di progettazione a quella di realizzazione in silicio.

Intendevo dire che è il gaming su PC che ahimè è destinato a scomparire per i ben noti problemi di impossibilità degli sviluppatori di tenere il passo con tutte le combinazioni di hardware esistenti in un mercato che premia invece console e al massimo su PC casual games (problema della pirateria a parte).

Non lo è infatti, per il semplice fatto che il "gaming" passerà in secondo piano negli anni venturi per il PC ed il nome di fisici sta proprio ad indicare l'importanza data all'uso della GPU per ambiti non ludici ma scientifici. Con penso nostro estremo dispiacere (per il focus sul gaming dico), ma è così.....il PC tornerà ad essere quello per cui è nato cioè una macchina per lavorare.....e che lavoro con questa potenza a disposizione

Nvidia Unveils Three Years Roadmap: Kepler and Maxwell Architectures Incoming - X-bit labs On Tuesday for the very first time in the history of Nvidia Corp. as well as graphics processors industry in general the company shared at its GPU Technology Conference the names and some of the features of its forthcoming graphics processor architectures. On the first day of the GPU Technology Conference (GTC), Nvidia has unveiled brief details about its next-generation graphics processing units (GPUs). Quite logically, the future processor architectures by the company - code-named Kepler and Maxwell - will be massively focused on general-purpose computing and will offer substantial performance increases compared to existing chips. Next year - sometimes in the second half of 2011 - Nvidia plans to release GPUs based on the Kepler architecture. The chips will be made using 28nm process technology and will bring tangible performance improvements compared to currently shipping graphics chips based on Fermi architecture. According to Nvidia, Fermi architecture is capable of achieving typical double precision (DP) performance of 1.5GFLOPS per watt. Kepler architecture will increase performance per watt by about 3 or 4 times, hence, it is possible to expect something like 1.125TFLOPS - 1.50TFLOPS of DP performance by a chip with 250W thermal design power. Although math performance with DP accuracy does not have a direct correlation with graphics performance it is possible to expect Kepler to be at least two or three times faster than Fermi in games. Nvidia Maxwell will be launched in 2013, according to chief executive of Nvidia Jen-Hsun Huang. Given the timeframe, it is logical to expect 20nm process technology to be used for manufacturing of Maxwell. The architecture due in three years from now will offer whopping 16GFLOPS of DP performance per watt, a massive improvement over current-generation hardware. "Between now and Maxwell, we will introduce virtual memory, pre-emption, enhance the ability of GPU to autonomously process, so that it's non-blocking of the CPU, not waiting for the CPU, relies less on the transfer overheads that we see today. These will take GPU computing to the next level, along with a very large speed up in performance," said Jen-Hsun Huang. It is noteworthy that Nvidia has decided to refresh the GPU architectures every two years, not in twelve - eighteen months as it used to do before and its rival ATI, graphics business unit of Advanced Micro Devices, does nowadays. It looks like Nvidia has faced rather massive limitations with process technologies from contract makers of semiconductors, which seems to slowdown the company's business. Still, even availability of process technologies does not limit Nvidia's abilities to refresh its actual products lineups to stay competitive.

Notiziona! "It's a pity Luca Barbieri or any Mesa / Gallium3D developers are not at Oktoberfest as they are deserving of more than a few Maß of Augustiner. In fact, today a new Gallium3D state tracker was pushed into Mesa and it's perhaps the most interesting state tracker for this open-source graphics driver architecture yet. It's a state tracker that exposes Microsoft's DirectX 10/11 API on Linux! And it's already working and can be hooked into Wine!"Luca Barbieri made a rather significant commit today that adds a state tracker dubbed "d3d1x", which implements the Direct3D 10/11 COM API in Gallium3D. Luca says this is just the initial version, but it's already working and can run a few DirectX 10/11 texturing demos on Linux at the moment. This is not a matter of simply translating the Direct3D calls and converting them to OpenGL like how Wine currently handles it, but is natively implemented within Gallium3D and TGSI to speak directly to the underlying graphics driver and hardware. Thanks to Gallium3D's architecture, this Direct3D support essentially becomes "free" to all Linux drivers with little to no work required." Per chi non sapesse cosa è Gallium3D: Link a Wikipedia

Una Radeon 5770 farebbe al caso tuo, ma siamo un po' oltre le 100 euro Altrimenti sempre per la stessa fascia una GeForce GTS 450.

Pubblico qui la notizia perchè magari a qualche uber-user interessa! Per conto mio erano mesi che aspettavo e non perchè sia fan boy ma perchè per uno sviluppatore il framework offerto da nvidia è moooooooooooolto completo. E con questo step direi che siamo veramente a buon punto. AMD svegliati a fare qualcosa di simile! (non basta l'ATI Stream, ci vuole un framework che invogli gli sviluppatori a lavorarci sopra integrandosi in VS!)

E' inutile A meno che tu ne sfrutti le capacità di GP Computing in applicativi che vogliono una MAREA di memoria. Difficile trovare nel pubblico "domestico" interessati, a meno di tesisti/dottorandi in quest'ambito.

Errore audio? Stai usando l'HDMI via scheda video per caso?

Notizia ancora più interessante: Intel Sandy Bridge many-core secret sauce ? The Register Hanno rivisto profondamente le cose (altro che tick tock, cosa che francamente non ho mai creduto potesse durare come approccio, anche perchè non ha più alcun senso nei system-on-a-chip, dato che il confine fra "CPU" e resto del die scompare pian piano ) nella comunicazione intrachip, e leggete questa frase nella seconda pagina: The ring is an ingenious beast. For one thing, as Kahn explains: "The ring itself is really not a [single] ring: we have four different rings: a 32-byte data ring, so every cache-line transfer — because a cache line is 64 bytes — every cache line is two packets on the ring. We have a separate request ring, and acknowledge ring, and a [cache] snoop ring — they're used, each one of these, for separate phases of a transaction." One nifty element of the design, and one that adds to Sandy Bridge's modularity, is the fact, as Kahn explained: "Each one of our stops on the ring is actually one clock, so we can run at core frequency between each of the cache boxes. Each time we step on the ring it's one clock." What's modulicious and scalariffic about that is "when the cores scale up, and they want high performance and high bandwidth and low latency," he said, "the cache box and the ring scale up with it, running at exactly the same frequency so you get shorter latencies." In other words, if you increase the clock speed of the compute cores, you increase the clock speed of the ring right along with them. While the ring may seem simple in concept, it's silicon-intensive in implementation. "We have massive routing," Kahn says. "The ring itself is more than a thousand wires, but the designers have found a way to route this over the last-level cache in a way that doesn't take up any more space." Cosa ancora più incredibile: The way that the ring interconnect communicates with the chip's various elements adds to Sandy Bridge's modularity and scalability, as well, since it doesn't really care how many cores and cache boxes it's talking to. Quindi aspettiamoci una grandissima moludarità/scalarità nel prodotti che verranno commerciati!

Ne parlavo giusto con delly alle 14.00! Se castrano la L3 (che è già ridotta come quantità tra l'altro ma ipotizziamo pure che la sua gestione sia migliorata, anche se ora deve lavorare anche per la GPU, almeno per chi non la disabilita ) la vedo grama!

E' come Penumbra (ma molto migliorato ), infatti consiglio anche quello Notare che insieme a STALKER è uno dei pochi giochi che supporta ancora la schede DX8! Chapeau!
