I am a research assistant professor at the University of Nebraska-Lincoln.

I program in many languages:

• Profiling the XRootD Monitoring Collector
  The XRootD Monitoring Collector (collector) receives file transfer accounting messages from XRootD servers. This transfer information is parsed by the collector and sent to the GRACC accounting database for visualization. Each transfer will generate multiple messages:
• Dashboards for Learning Data Visualizations
  Creating dashboards and data visualizations are a favorite past time of mine. Also, I jump at any chance to learn a new technology. That is why I have spent the last couple of months building dashboards and data visualizations for various projects while learning several web technologies.
• Improving the Open Science Data Federation’s Cache Selection
  Optimizing data transfers requires tuning many parameters. High latency between the client and a server can decrease data transfer throughput. The Open Science Data Federation (OSDF) attempts to optimize the latency between a client and cache by using GeoIP to locate the nearest cache to the client. But, using GeoIP alone has many flaws. In this post, we utilize Cloudflare Workers to provide GeoIP information during cache selection. During the evaluation, we found that location accuracy grew from 86% accurate with the original GeoIP service to 95% accurate with Cloudflare Workers.
• XRootD Client Manager
  The validation project for XRootD Monitoring is moving to phase 2, scale testing. Phase 1 focused on correctness of single server monitoring. The report is available.
• GRACC Transition Visualization
  The OSG is in the progress of transitioning from an older ElasticSearch (ES) cluster to a new version. Part of this process is reindexing (copying) data from the old to the new. Unfortunately, it’s not easy to capture a status of this transition. For this, I have created the GRACC Transition page.
