Network Performance with PerfSONAR Checker

Note: This blog post has been updated in January 2023 after moving the perfsonar-checker app from development to production.

PerfSONAR is a popular tool to measure network bandwidth and latency between between hosts in a network. We’ve built an application that can be easily deployed on a SLATE cluster to check connectivity against production endpoints we operate on the SLATE platform. This should be a handy tool that cluster administrators can use to check out a newly installed cluster.

Update Root Certificate (Let's Encrypt)

After the Let’s Encrypt root certificate expired at the end of September 2021, a few people are still experiencing a certificate expired warning on our websites. We have updated our websites with the current certificate; however, some users may need to update the certificate on their computers. Specifically, we have seen this issue with Mac OS.


Using SLATE to Enable Remote Desktop in Open OnDemand

Open OnDemand is a web application enabling easy access to high-performance computing resources. Open OnDemand, through a plugin system, provides many different ways to interact with these resources. Most simply, OnDemand can launch a shell to remote resources in one’s web browser. Additionally, OnDemand can provide several ways of submitting batch jobs and launching interactive computing sessions. It is also able to serve as a portal to computationally expensive software running on remote HPC nodes. For example, users can launch remote Jupyter Notebooks or Matlab instances.

The SLATE platform provides a simple way to deploy this application with a batch job scheduler in a containerized environment, with remote desktop and shell access to any desired backend compute resources.
