  1. Distributed Tera-Mining R. L. Grossman Laboratory for Advanced Computing University of Illinois & Magnify, Inc.

  2. Trend 1. Explosion of Data …

  3. … All in the Wrong Format With no one to analyze it.

  4. The Data Gap Most data comes a GB and a TB at a time. The Data Gap Total new disk (TB) since 1995 New Ph.D.s

  5. Trend 2. Sonet is dead. Lambda Rules. Gigabytes can be moved in seconds.

  6. Trend 3: Most Data is Distributed • Bush’s Law: The usefulness of a column of data varies as the square of the number of columns it is compared to.

  7. Example 1: ENSO & Cholera El Nino Data at NCAR Cholera Data at WHO

  8. Table 2 Table 1 Example 2: Voting

  9. Correlation: Reform Voters vs Votes for Buchanan Palm Beach

  10. DataSpace – One Approach to Making Data Useful Complementary to the grid, which we view as a distributed computer. • html • http • search by keyword • workstations servers • pmml & dtml • dstp • correlate & mine • data & compute clusters • 16 terabytes of documents • 4 billion documents Today’sMulti-media Web Tomorrow’sData Web • petabytes of data • tens of billions to trillions of records

  11. DSTP Server 2 DSTP Server 1 k[i], y[j] k[i], x[i] Click to obtain graph UCK [uckid] attributes [aid]

  12. Terra Mining Testbed Optical testbed for distributed tera miningof scientific data. Goal also to be testbed forbroadband based business services.

  13. Lessons Learned • It’s the data stupid. Cycles, cylinders & lambdas are all commodities. • The fundamental challenge: lower the cost to make data useful. • The emergence of internet infrastructure for data is inevitable. Opens up possibilities for new types of scientific discoveries.

  17. OC-3 OC-12 OC-48 Trend 2. Bandwidth is a Commodity

  18. El Nina Anomalies

  19. Indonesia Cholera Cases

  20. Cholera Cases

  21. Distributed Exabytes (New Disks) Petabytes 1 Exabyte Source: IDC (1999) "1999 Winchester Disk Drive Market Forecast and Review"

  22. Trend 3: Most Data is Distributed • W’s Law: The usefulness of a column of data varies as the square of the number of columns it is compared to.

  23. Example 2: Voting

  24. Database 1: Total Votes for Buchanan by County

  25. Database 2: Total Registered Reform Voters by County
