Korea@Home Project? Maybe, most of you know SETI@Home Folding@Home Distributed. net And many other distributed computing like them 2

Architecture Client/Server Style Partitioning a work into many jobs • Data or Computational Intensively Distributing the jobs into available PCs Aggregating back the computing results 3

Design Goals For customers with application Easy to use General enough to support a variety of applications Correctness For PC resource providers Transparent not to bother Secure and privacy-guarantee Compensation For Server Scalable Adaptable 4

Status in 2002 Construct a platform 4 components of servers • • Main Control server Authentication server Scheduling and distribution server Database Agent for PCs Experiment on the platform Virtual Screening for New Drug Design 5

2003 and Future Plan Architecture Hybrid P 2 P For more scalable, data sharing Complementary Studies Fault-tolerance Security More subscribers up to 50, 000 New applications Explore compatibilities with GRID Variety of resources 6

Virtual Screening Target Protein Chemical DB Share Clinical Test Analysis A protein CDK 2 for cancer Developing Manufacturing new drug 50, 000 chemical molecules Virtual High-Throughput Screening + + Client 1 + Calculating Protein Active Site PMI + Client 2 Calculating ligand PMI Server + Searching for a new drug-candidates + Client 3 Internet Calculating the initial structure of PMI 7

Experiments and Results 4 days in Aug. 2002 1, 217 PCs of anonymous volunteers About 2 hours and 40 minutes Performance Peak time 53. 5 Gflops / Average 31. 78 Gflops 320 hours with one PC of Pentium III 550 MHz United Devices (http: //www. ud. com) 1. 7 million subscribers: 39. 1 Tflops Converting the result as 1. 7 million subscribers: 46. 7 Tflops (current fastest supercomputer NEC Earth Simulator 40. 96 Tflops) 8

Opportunities in Korea Over 10 million x. DSL users Advanced Network Infrastructure More rapid cycle of purchasing new PCs 9
