is it possible to make a cluster of ALL computers linked by the Internet ?

Question

I mean something like Apple's Xgrid or Seti @ Home

the connection from my Mac to the wireless router goes at 130 Mb , suppose that using Rendezvous aka Bonjour , you're able to connect automatically to nearby laptops ,something like the "Foneros" are doing in Spain,isn't that enough to share unused CPU ?

Answer 1

Theoretically? Possible. Practically? nope. Too much variety of OS and performance, too much overhead in managing the workload across a slow interconnection.

Have a look at Nasa's beowulf clustering... it needs high speed networking (and DSL doesn't cut it as high speed .5 - 2 Mbit download / less upload compared to 100Mbit LAN)... plus you get less and less benefit for each computer you add to the cluster.

Answer 2

Theoretically yes, Realistically no. Do you honestly think everyone out there would install some sort of program on their pc/server/etc to do this?

Answer 3

of course it's possible...as a matter of fact, I am doing it right now and taking control of your computer!
