What’s new in PowerAI 1.6.0

PowerAI 1.6.0 builds upon the previous releases and includes the following updates and new features:

  • PowerAI is now packaged as Conda packages and no longer as RPM packages.
    • PowerAI Conda packages are available in a Conda channel
    • There is no install package to download, instead connect to the PowerAI Conda channel and install your packages from there
    • Package dependencies are automatically resolved
    • Delivery of packages is open and continuous
  • CUDA, cuDNN, and NCCL are now packaged as Conda packages installed by PowerAI. Only the NVIDIA driver needs to be manually installed.
  • You can now run more than one framework at the same time in the same environment. For example, you can run TensorFlow and PyTorch at the same time.
  • Supported hardware:
    • IBM Power System AC922 with NVIDIA Tesla V100 GPUs

We recommend that you install the most current release of PowerAI, however, if you have an earlier version installed, you can find release information in the IBM Knowledge Center:

Requesting enhancements for IBM PowerAI

The IBM Request for Enhancement (RFE) tool is now available for you to submit formal enhancement requests to the PowerAI development team. One of the benefits of using the RFE tool is that other clients can vote on submitted requirements, which helps IBM to prioritize requests.

Get started

Go here get started: ibm.biz/powerai-rfe

The RFE for PowerAI pages are part of IBM Developer and require that you sign in with an IBM ID to submit or vote on a request. You should make sure that your IBM ID profile includes your current company and your email address to ensure that we can contact you if we have questions.

Search first

Once on the RFE page, click on the “Search” tab to view existing requests before you submit a new request. It is much more useful to vote for a previously submitted request than to submit a duplicate request.
