OSG resources at PACE

The Buzzard is an NSF funded cluster through a CC* award 1925541. This cluster represents a centralized OSG service support structure at Georgia Tech that provides researchers an opportunity to invest their research funding directly into OSG resources, and the currently deployed cluster has already a faculty contribution of 25 nodes to the Buzzard cluster.

At present, the Buzzard cluster supports the computational needs of the CRA as they investigate multi-messenger physics through several experiments/projects, including - Laser Interferometer Gravitational-Wave Observatory (LIGO), - IceCube Neutrino Observatory, - Cherenkov Telescope Array (CTA), and - Very Energetic Radiation Imaging Telescope Array System (VERITAS).

In addition, 10% of the CC* funded part of the Buzzard cluster (or 3% of the overall cluster) is allocated to the OSP.
