A first look at the upcoming AIXPRT learning tool

Last month, we announced that we’re working on a new AIXPRT learning tool. Because we want tech journalists, OEM lab engineers, and everyone who is interested in AIXPRT to be able to find the answers they need in as little time as possible, we’re designing this tool to serve as an information hub for common AIXPRT topics and questions.

We’re still finalizing aspects of the tool’s content and design, so some details may change, but we can now share a sneak peak of the main landing page. In the screenshot below, you can see that the tool will feature four primary areas of content:

  • The FAQ section will provide quick answers to the questions we receive most from testers and the tech press.
  • The AIXPRT basics section will describe specific topics such as the benchmark’s toolkits, networks, workloads, and hardware and software requirements.
  • The testing and results section will cover the testing process, the metrics the benchmark produces, and how to publish results.
  • The AI/ML primer will provide brief, easy-to-understand definitions of key AI and ML terms and concepts for those who want to learn more about the subject.

We’re excited about the new AIXPRT learning tool, and will share more information here in the blog as we get closer to a release date. If you have any questions about the tool, please let us know!

Following up with MobileXPRT 3 on Android 11

As we discussed last week, we’ve learned that MobileXPRT 3 is crashing after installation on some Android 11 phones. We now know what is causing this behavior: changes to the storage strategy and permissions requirements in Android 11. The new file storage strategy is called scoped storage. By default, scoped storage restricts an app’s storage access to app-specific directories and media, and prohibits general access to external or public directories. This default setting requires an opt-in permissions prompt that MobileXPRT 3 does not currently have. It also prevents third-party apps such as email clients or file managers from being accessing MobileXPRT 3 results files.

To fix this, we are planning to rebuild MobileXPRT 3 to (1) point all of the benchmark’s file references to its private directory, and (2) allow users to zip results files and attach them to results submission emails. While we do not expect that either of these changes will affect performance results, we’ll perform testing to confirm this before we publish the new build.

We don’t expect these changes to take too long, and will keep you updated here in the blog. If you have any questions about the update process or MobileXPRT 3, please let us know!

New MobileXPRT 3 installations may crash on Android 11

We recently received a tech support inquiry about problems with new MobileXPRT 3 installations on some Android 11 phones. The tester installed MobileXPRT 3 on a selection of phones running Android 11, and the app crashed immediately upon opening. We were able to reproduce the issue on multiple phones in our lab, and currently know that the issue may happen on the Google Pixel 3, Google Pixel 4a 5G, Google Pixel 4XL, Google Pixel 5, and the OnePlus 8T (running Android 11 with an Oxygen OS skin).

MobileXPRT 3 continues to run without issues on Android 9 and 10 phones. When we updated an Android 10 phone with an existing MobileXPRT 3 installation to Android 11, we found that the benchmark ran successfully. This suggests a lack of fundamental incompatibilities between MobileXPRT 3 and current versions of Android 11. Because some of our lab techs experienced crashes immediately after the app asked for permissions, we think it’s possible that new permissions-setting requirements in Android 11 are causing the problem.

We’re currently working to isolate the problem and identify a course of action. We’ll share more information here in the blog as soon as possible. If you’ve encountered this problem in your testing, we apologize for the inconvenience, and we’re thankful for your patience as we work towards a solution.

If you have any information you’d like to share about running MobileXPRT 3 on Android 11, please let us know!

Next up: a white paper about the CloudXPRT data analytics workload

Soon, we’ll be publishing a CloudXPRT white paper that focuses on the benchmark’s data analytics workload. We summarized the workload in the Introduction to CloudXPRT white paper, but in the same way that the Overview of the CloudXPRT Web Microservices Workload paper did, the new paper will discuss the workload in much greater detail.

In addition to providing practical information about the installation package and minimum system requirements for the data analytics workload, the paper will describe test configuration variables, structural components, task workflows, and test metrics. It will also include guidance on interpreting test results and submitting them for publication.

As we’ve noted, CloudXPRT is one of the more complex tools in the XPRT family, with no shortage of topics to explore. Possible future topics include the impact of adjusting specific test configuration options, recommendations for results reporting, and methods for results analysis. If there are specific topics that you’d like us to address in future white papers, please feel free to send us your ideas!

We hope that the upcoming Overview of the CloudXPRT Data Analytics Workload paper will serve as a go-to resource for CloudXPRT testers, and will answer any questions you have about the workload. Once it goes live, we’ll provide links in the Helpful Info box on CloudXPRT.com and the CloudXPRT section of our XPRT white papers page.

If you have any questions, please let us know!

Following up

This week, we’re sharing news on two topics that we’ve discussed here in the blog over the past several months: CloudXPRT v1.01 and a potential AIXPRT OpenVINO update.

CloudXPRT v1.01

Last week, we announced that we were very close to releasing an updated CloudXPRT build (v1.01) with two minor bug fixes, an improved post-test results processing script, and an adjustment to one of our test configuration recommendations. Our testing and prep is complete, and the new version is live in the CloudXPRT GitHub repository and on our site!

None of the v1.01 changes affect performance or test results, so scores from the new build are comparable to those from previous CloudXPRT builds. If you’d like to know more about the changes, take a look at last week’s blog post.

The AIXPRT OpenVINO update

In late July, we discussed our plans to update the AIXPRT OpenVINO packages with OpenVINO 2020.3 Long-Term Support (LTS). While there are no known problems with the existing AIXPRT OpenVINO package, the LTS version targets environments that benefit from maximum stability and don’t require a constant stream of new tools and feature changes, so we thought it would be well suited for a benchmark like AIXPRT.

We initially believed that the update process would be relatively simple, and we’d be able to release a new AIXPRT OpenVINO package in September. However, we’ve discovered that the process is involved enough to require substantial low-level recoding. At this time, it’s difficult to estimate when the updated build will be ready for release. For any testers looking forward to the update, we apologize for the delay.

If you have any questions or comments about these or any other XPRT-related topics, please let us know!
