CNTK v.2.0 Beta 5 Release Notes

This is a summary of new features delivered with the Beta 5 release of CNTK V.2.0.

Windows: The Microsoft Cognitive Toolkit and NVIDIA Cuda 8

With this Beta release the Windows version of the Cognitive Toolkit supports NVIDIA Cuda 8. The binary beta 5 packages are built using the NVidia Cuda 8 toolkit. If you are a developer and building CNTK on your own system you can still continue using Cuda 7.5. This will change soon, please read details here.

Linux: The Microsoft Cognitive Toolkit and NVIDIA Cuda 8

In this Beta the Microsoft Cognitive Toolkit is only supporting NVIDIA Cuda 7.5 on Linux. We expect to move the Linux version of the toolkit to Cuda 8 shortly.

CNTK Evalaluation Library / Nuget Package

A new Nuget package with the latest eval DLL (managed and native) is available. The EvaluateRgbImage function in the managed Eval API improves speed of image evaluation.

Performance

In the CNTK Text Format deserializer the memory footprint is reduced significantly. This will improve performance and scalability.
