# Release Notes for Ocula 4.0v2

# Release Date

September 2016

## Minimum System Requirements

• A version of Nuke 8.0 on:

• Mac OS X 10.7 (Lion), 10.8 (Mountain Lion), or 10.9 (Mavericks)

• Windows 7 64-bit and Windows 8 64-bit

• CentOS/RHEL 5 and CentOS/RHEL 6

• A version of Nuke 9.0 or Nuke 10.0 on:

• Mac OS X 10.9 (Mavericks) and Mac OS X 10.10 (Yosemite)

• Windows 7 64-bit or Windows 8 64-bit

• Linux CentOS/RHEL 5 or CentOS/RHEL 6

• Foundry Licensing Tools (FLT 7.0v2 or later) for floating licences.

## Requirements for GPU Acceleration

To take advantage of GPU acceleration on Nuke 9.0 and Nuke 10.0, you must have, either:

• An NVIDIA GPU with compute capability 2.0 (Fermi) or above. A list of the compute capabilities of NVIDIA GPUs is available at www.nvidia.co.uk/object/cuda_gpus_uk.html

Note: The compute capability is a property of the GPU hardware and can't be altered by a software update.

With graphics drivers capable of running CUDA 4.2 or above.

• On Windows and Linux, CUDA graphics drivers are bundled with the regular drivers for your NVIDIA GPU. Drivers from April 2012 onward support CUDA 4.2.

Go to http://www.nvidia.com/Download/Find.aspx?lang=en-us for more information.

• On Mac, the CUDA driver is separate from the NVIDIA graphics driver and must be installed, if you don't have it already. The minimum requirement for CUDA 4.2 is driver version 4.2.5 which can be downloaded from www.nvidia.com/drivers.

Note: We recommend using the latest graphics drivers, where possible, regardless of operating system.

• an AMD FirePro GPU on late 2013 Mac Pro 6,1 and mid 2015 Mac Pro 11,5, running OS X 10.9.3 (Mavericks), or later (see below and the Blink API documentation for caveats on CPU/GPU result consistency on Mac Pros).

# New Features and Enhancements

• Ocula is now supported on Nuke 10.0 for all platforms.

• Ocula is now supported on Nuke 9.0 for all platforms.

• Ocula now supports OpenCL processing on late 2013 Mac Pro 6.1, running OS X 10.9.3 'Mavericks', or later.

Note: The output between the GPU and CPU is identical on NVIDIA GPUs. With the addition of support for AMD GPUs on late 2013 Mac Pro, the bit-wise equality between OpenCL GPUs and CPUs generally holds, but for some operations there are limitations to the accuracy possible with this configuration.

Note: OpenCL processing is only available for Ocula in Nuke 9.
