1. Distributed Data Storage and Parallel Processing Engine Sector & Sphere Yunhong Gu Univ. of Illinois at Chicago

4. Motivation Super-computer model: Expensive, data IO bottleneck Sector/Sphere model: Inexpensive, parallel data IO, data locality

5. Motivation Parallel/Distributed Programming with MPI, etc.: Flexible and powerful. But too complicated Sector/Sphere model (cloud model): Clusters are a unity to the developer, simplified programming interface. Limited to certain data parallel applications.

6. Motivation Systems for single data centers: Requires additional effort to locate and move data. Sector/Sphere model: Support wide-area data collection and distribution.

7. Sector Distributed File System Security Server Masters slaves slaves SSL SSL Clients User account Data protection System Security Metadata Scheduling Service provider System access tools App. Programming Interfaces Storage and Processing Data UDT Encryption optional

Sphere: Simplified Data Processing for each file F in (SDSS datasets) for each image I in F findBrownDwarf(I, …); SphereStream sdss; sdss.init("sdss files"); SphereProcess myproc; myproc->run(sdss," findBrownDwarf ", …); myproc->read(result); findBrownDwarf(char* image, int isize, char* result, int rsize);
