OSiRIS or MI-OSiRIS (Multi-Institutional Open Storage Research Infrastructure) will combine a number of innovative concepts to provide a distributed, multi-institutional storage infrastructure that will allow researchers at any of our three campuses to read, write, manage and share their data directly from their computing facility locations.
Our goal is to provide transparent, high-performance access to the same storage infrastructure from well-connected locations on any of our campuses. We intend to enable this via a combination of network discovery, monitoring and management tools and through the creative use of CEPH features.
By providing a single data infrastructure that supports computational access on the data "in-place", we can meet many of the data-intensive and collaboration challenges faced by our research communities and enable these communities to easily undertake research collaborations beyond the border of their own Universities.
OSiRIS is a collaboration between University of Michigan, Wayne State University, Michigan State University, and Indiana University funded by the NSF under award number 1541335. Many other institutions will collaborate as scientific users as the project becomes established.
Pythia Network Diagnosis Infrastructure
PuNDIT will integrate and enhance several software tools needed by the High Energy Physics (HEP) community to provide an infrastructure for identifying, diagnosing and localizing network problems. In particular, the core of PuNDIT is the Pythia tool that uses perfSONAR data to detect, identify and locate network performance problems. The Pythia algorithms, originally based on one-way latency and packet loss, will be re-implemented incorporating the lessons learned from its first release and augmenting those algorithms with additional metrics from perfSONAR throughput and traceroute measurements. The PuNDIT infrastructure will build upon other popular open-source tools including smokeping, ESnet's Monitoring and Debugging Dashboard (MaDDash) and the Open Monitoring Distribution (OMD) to provide a user-friendly network diagnosis framework.
At UM in West Hall we have installed a 50" LCD display dedicated to showcasing ATLAS Live video content. ATLAS Live is a project designed to facilitate the communication of current detector and organizational information in real time to the collaboration and beyond. The Live Video project uses professional signage software to create webcasts for viewing in a standard web browser, an iPhone or other portable device, and on HD displays at CERN or anywhere in the world.
perfSONAR is an infrastructure for network performance monitoring, making it easier to solve end-to-end performance problems on paths crossing several networks. It contains a set of services delivering performance measurements in a federated environment. AGLT2 was an early adopter and tester of the pS-Performance Toolkit and we have special interest in the project as a tool in improving network throughput.
