Announcing Multi-GPU Support with Elemental Accelerator 2.2
Elemental is pleased to announce the release of Elemental Accelerator 2.2 for Windows, an important update to its GPU-accelerated video processing plug-in for Adobe® Premiere® Pro CS4. With the release of 2.2, Elemental Accelerator provides support for video encoding using multiple NVIDIA Quadro FX GPUs. Multi-GPU functionality efficiently divides the encoding workload among all supported GPUs in a system, radically increasing overall export speed and performance. A multi-GPU implementation is well-suited to platforms with multiple PCI-E slots available to accommodate more than one NVIDIA Quadro FX graphics card, such as Z Series workstations from HP and ThinkStation workstations from Lenovo.
Supported multi-GPU configurations are:
• 2 x NVIDIA Quadro FX 4800
• 2 x NVIDIA Quadro FX 3800
• 2 x NVIDIA Quadro FX 1800
Although performance improvements will vary depending on GPU(s), video source and export settings, Elemental Accelerator provides a dramatic speed increase over the standard CPU-only encoder when leveraging multiple GPUs. In the following test case, encoding AVCHD 1080p source video to H.264 720p output can be performed nearly six times faster with Elemental Accelerator than with the standard encoder available with Adobe Premiere Pro.

Release 2.2 also expands the lineup of GPUs supported by Elemental Accelerator. The NVIDIA Quadro FX 3700 graphics card and the NVIDIA Quadro FX 3800M, 2800M and 1800M mobile GPUs have been added to the suite of NVIDIA GPUs that will run with Elemental Accelerator, giving more options than ever to video professionals, particularly those creating content on-the-go. For a complete list of supported GPUs, please visit the Elemental Accelerator specifications page on the Elemental website.
In addition, release 2.2 of Elemental Accelerator offers new H.264 and MPEG-2 presets for a variety of target applications, including presets designed specifically for the iPhone and for Blu-ray.
If you are an existing Accelerator customer, be sure and visit the Elemental updates site to download and install release 2.2. Customers installing from a CD or web package for the first time can elect to update immediately after an initial install.
For users who already own RapiHD or Elemental Accelerator, you can easily upgrade to the newest version. To access an update:
1. Launch Adobe Premiere Pro CS4
2. Navigate to the Export Settings dialog box
3. Select the More Info tab
4. Press the Check for updates button
This will automatically direct you to the Elemental Accelerator update site.
Elemental Accelerator 2.2 is made exclusively for NVIDIA Quadro GPUs. On the desktop, Elemental Accelerator works with the Quadro CX as well as the Quadro FX 5800, 4800, 3800, 3700 and 1800. On mobile platforms, Elemental Accelerator works with the Quadro FX 3800M, 2800M, 1800M, 3700M and 2700M. Elemental Accelerator is available for purchase as a standalone package from NVIDIA’s Adobe plug-in store or bundled with supported Quadro FX graphics cards from a variety of resellers.
