Nvidia CUDA 1.0 now available   Posted on 26/06/2007 at 17:56 by Damien

	Nvidia just updated its CUDA to version 1.0. Since the beta version 0.8 was arrived 4 months ago, the CUDA driver, compiler, and available tools have strongly evolved. Most of these evolutions were integrated in the version 0.9, which however wasn’t public. Amongst the main additions, there is asynchronous functioning of CUDA, which now frees up the CPU while the program is executed on the GPU. CUDA 1.0 also supports atomic functions but only on the GeForce 8600 and 8500. Interactions between CUDA and graphic APIs have slightly gained in flexibility, even if this isn’t a current priority for CUDA. The SDK also has evolved and has several new demos. All of this is available on the Nvidia development website.

Hybrid SLI: at least it’s a good idea   Posted on 26/06/2007 at 00:22 by Nicolas - source: X-bit labs

	Our colleagues at X-bit labs published some information involving Nvidia’s future Hybrid SLI technology, which consists of using an integrated graphic core and a graphic card. Two functioning modes are planned. The Power Saving mode, which will permit deactivation when graphic cards use only the motherboard’s IGP, is of interest in terms of power consumption, heat dissipation or noise levels. On the other hand, the « Max » Performance mode, which will allow the IGP to help graphic cards with the Californian manufacturer’s inexpensive GPUs (entry or mid level) in order to accelerate rendering speeds, makes us smile when we think of the overall power of the GPUs and IGPs in question.

Seagate’s Barracuda 7200.11 & ES.2 1TB   Posted on 26/06/2007 at 00:09 by Nicolas - source: Seagate

	Today, Seagate unveiled two hard drives with 1 TB capacity, with large volumes arriving in the third quarter. They each have four platters with a density of 250 GB. This is real progress compared to the Hitachi 7K1000 with its five 200 GB platters, however, it’s still below the Spintpoint F1 1TB from Samsung, which has three 333GB platters. The maximum sequential rates of the new Seagate 7200 Rpm discs are a respectable 105 MB /s. There is minimal information on the Barracuda 7200.11; it functions with the SATA-II standard, has a 32 MB cache, and an average latency time of 4.16 ms, without anymore information on its performances in practice. The noise level is announced at 27 dBA in stand-by and 29 dBA in rotation. The recommended retail price should be around 360 € (tax included). Seagate was a little more talkative about the Barracuda ES.2 destined for the professional market. The American manufacturer announced average access times in reading/writing of 8.5ms and 9.5ms respectively. Average latency is at 4.16 ms. The SATA version can have either a 16 or 32 MB cache, while the one using the SAS interface is limited to 16MBo. The noise level in stand-by is 27 dBA.
