Use of (idle) computer interconnected by Internet for processing large throughput applications

• Use of (idle) computer interconnected by Internet for processing large throughput applications

• Ex: SETI@HOME

• 5M+ users since launching
• 20013/10: 1,4M users, 3,5M computers; 135k active users, 190k active computers
• 625 Tflops (average 505 Tflops)!
• 233 « countries »
• 2M years of CPU time since 1999;
• BOINC infrastructure (Décrypthon, RSA-155…)
• much less active than it used to be (:2 since 2011)

• Programmer view: a single master, n servants
