7. USA-Russia Lightpath for Fast Data Transfer of Terabyte-sized Scientific Datasets National Center for Data Mining (NCDM) at the University of Illinois at Chicago, Geophysical Center RAS and Space Research Institute RAS have successfully moved 1.4 TB of data in 4.5 hours over a 1 Gbps lightpath between Chicago and Moscow as part of the Teraflow Network initiative Using NCDM’s open-source UDP-based Data Transfer protocol (UDT), we were able to transfer the MS SQL database with SDSS astronomy catalog. The 2.5 TB database dump was compressed to 1.4 TB, split into 60 files, transferred over a 1 Gbps lightpath and then decompressed in Moscow and loaded back to MS SQL Server The SkyServer portal and the SDSS database were developed by Jim Gray at MSR and Alex Szalay at JHU. Russian language mirror now resides at www.skyserver.ru in Moscow Direct Lightpath link from IKI in Moscow to NGDC NOAA in Boulder has been successfully tested

9. Past Observations + Predictive Model = Reanalysis 1.Direct observations in the past – including raw and processed data, e.g. meteorological station or satellite, 10 5 observations of atmosphere each 6 h 2.Predictive numerical model – “knows” physics, uses direct observations as boundary values, e.g. Global Circulation Model, 360 lat X 180 lon X 20 levels X 100 parameters= 1.3 X 10 8 data values each 6 hours 3.Reanalysis – accumulated output of the numerical model forecasts each corrected for the available direct observations for a long time period, 50 years at 6 h time step

10. Why OGSA-DAI service container? Standard tool in the Grid community Supports distributed workflow (in version 3.*) Built in support for asynchronous transactions Compatible with Web (Axis) and Grid (OMII, UNICORE, GT4) Looked at alternatives like OpenDap, WCS, … –documentation of our analysis is available Problem 1: it is very complex – Solution: REST wrapper Problem 2: supports only File, SQL and XML data types and queries – Solution: implement additional data sources and functions for data in multidimensional arrays

15. Above the Clouds: A Berkeley View of Cloud Computing Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we call a Cloud. When a Cloud is made available in a pay-as-you-go manner to the public, we call it a Public Cloud; the service being sold is Utility Computing: AmazonWeb Services, Google AppEngine, and Microsoft Azure. http://www.eecs.berkeley.edu/Pubs/TechRpts/2009/EECS-2009-28.html

17. How to deploy SPIDR in Cloud? Single instance: S3 EBS EC2 SPIDR webapp & web services MySQL databases Database dump File system snapshot VM snapshot bundle VM image

18. Can we support multiple SPIDRs? In different Amazon cloud regions? Yes! Launch several instances of the SPIDR VM Configure DNS round-robin for load balancing Run MySQL master on the first instance, and MySQL slaves on others or Use third-party high-availability products for Amazon cloud, such as RightScale
