Science Drivers

Here are some of the many scientific research projects that have motivated CHERuB and that will take advantage of its expanded research Internet bandwidth:

GORDON

Gordon is a unique data-intensive computational resource operated by the San Diego Supercomputer Center (SDSC) and funded by the NSF under a cooperative agreement OCI-0910847 with UCSD. Professor Michael Norman is the PI of the project. Gordon entered production in early 2012, and is accessible to national academic researchers with data-intensive computing applications through the NSF Extreme Science and Engineering Discovery Environment (XSEDE) program.

CMMAP

CMMAP takes advantage of rapidly increasing computer speed to achieve major advances in our ability to understand and predict the effects of clouds on weather and climate.  To do this, ~3.5PB/year of data needs to be moved from various high performance computing centers to our GORDON supercomputer here at SDSC for analysis. John Helly is the local lead on this project.

POLARBEAR

Polarbear is an observational cosmology project funded by the NSF and conducted by an international consortium of universities to detect the signatures of inflation in the cosmic microwave background. UCSD's team, led by co-PI Brian Keating, is responsible for analysis of all the cosmological and calibration data. Some 10 PB of data will need to be moved to SDSC over the life of the project.

Experimental Particle Physics

UCSD (PI Frank Würthwein) supports one of seven U.S. Tier Two distribution site for data from the CMS project at the Large Hadron Collider (LHC), accepting data from FNAL and distributing it to scientists across the U.S. In addition to this data distribution role, Gordon and other future supercomputers will process CMS data. When the LHC turns back on in 2015, we expect to be processing up a Petabyte of data twice a year at SDSC.

The Open Science Grid

UCSD (PI Frank Würthwein) is co-PI of the OSG Project, a grant jointly funded by NSF and DOE. The new connection between UCSD and CENIC/Pacific Wave will dramatically improve the bandwidth between UCSD HEP and the numerous users served by the networks connected through Pacific Wave (including Internet2 and ESnet) and at the many California universities that are part of CENIC.

Prism@UCSD

Dr. Phil Papadopoulos is developing the NSF-supported Prism@UCSD at UCSD.  Prism@UCSD is an intra-campus multi-terabit-class Nx40G research network at UCSD with layer 1 and layer 2 endpoints offering dedicated service to researchers in a variety of fields, including the High-Energy Physics experimental particle physics and Open Science Grid projects of Dr. Frank Würthwein described above; the NSF-funded Ocean Observatories Initiative (OOI); high resolution electron microscopy imaging at the National Center for Microscopy Imaging Research (NCMIR); high-definition video and digital media (CineGrid); 3D virtual reality (StarCave); marine microbial metagenomics (CAMERA) and other data-intensive areas.

Prism@UCSD is designed to provide high-burst-rate bandwidth for large cross-campus data streams beyond that which is available on the campus production network. Designed in a star configuration with a high-performance Arista switch at its core, its “big data freeway system” of high-bandwidth end-to-end optical connections will support interdepartmental collaboration, big data storage and computation on centralized Research Cyberinfrastructure resources, and allow researchers in one part of campus to transmit large data sets for analysis by researchers on another part of campus.
