pScheduler API Workshop available in YouTube Channel

Posted September 20, 2017 - permalink

The perfSONAR Project team is pleased to announce the release of pScheduler API Workshop's recording on Project's YouTube channel.

pScheduler is the new test scheduler introduced in perfSONAR 4.0. One of its features is a REST API, which turns perfSONAR nodes into building blocks for other systems, reducing the need to build up additional remote measurement infrastructure, and ensuring more-accurate results by working cooperatively around other measurement activities. From a practical standpoint, this feature allows the user to give pScheduler measurement tasks, retrieve the results, and analyze important information about the system and the tasks it's performing.

Topics covered in this workshop include: reviewing the basic concepts, generation of tasks, the task lifecycle, retrieval and formatting of results, enumeration of installed plug-ins, and examination of pScheduler’s timeline.

Posted April 17, 2017 - permalink

perfSONAR 4.0 is now available! perfSONAR 4.0 is a significant update to the perfSONAR software and brings about many changes we hope will strengthen the foundation on which the project is built going forward. Thank you to all those in the community that helped test and provide feedback over the past few months. We would also like to thank everyone for their patience. This release incorporates possibly the largest single change in perfSONAR’s 15-year history, and we spent considerable time making sure it was right.

Changes in 4.0 include:

  • New scheduling software called pScheduler that provides increased visibility, extensibility and control in the measurement process.
  • CentOS 7 support
  • Debian perfsonar-toolkit bundle support
  • Updated graphs
  • Support for email alerting in MaDDash

For a complete list of changes and important upgrade notes see

If you are running auto-updates you should get perfSONAR 4.0 automatically. For others see our documentation on how to get the software. Also, please review our hardware requirements, in particular with respect to CPU, as there have been some changes, specifically for those hosts planning to run and store a large number of tests.
